Abstract
BACKGROUND In the United States, buffalofish (Ictiobus spp.) are sporadically associated with sudden onset muscle pain and weakness due to rhabdomyolysis within 24 h of fish consumption (Haff disease). Previous genetic analyses of case-associated samples were unable to distinguish the three species of buffalofish that occur in the US, Ictiobus cyprinellus (bigmouth buffalo), Ictiobus bubalus (smallmouth buffalo), and Ictiobus niger (black buffalo). METHODS Ten events were investigated between 2010 and 2020 and demographic and clinical information was collected for 24 individuals. Meal remnants were collected from 5 of 10 events with additional associated samples (n = 24) collected from another five of 10 events. Low-coverage whole-genome sequencing (genome skimming) was used to identify meal remnants. RESULTS Patients (26-75 years of age) ranged from 1-4 per event, with 90% involving ≥2 individuals. Reported symptoms included muscle tenderness and weakness, nausea/vomiting, and brown/tea-colored urine. Median incubation period was 8 h. Ninety-six percent of cases were hospitalized with a median duration of four days. The most commonly reported laboratory finding was elevated creatine phosphokinase and liver transaminases. Treatment was supportive including intravenous fluids to prevent renal failure. Events occurred in California (1), Illinois (2), Louisiana (1), New York (1), Mississippi (1), Missouri (2), New Jersey (1), and Texas (1) with location of harvest, when known, being Illinois, Louisiana, Mississippi, Missouri, Texas, and Wisconsin. Meal remnants were identified as I. bubalus (n = 4) and I. niger (n = 1). Associated samples were identified as I. bubalus (n = 16), I. cyprinellus (n = 5), and I. niger (n = 3). DISCUSSION Time course, presentation of illness, and clinical findings were all consistent with previous domestic cases of buffalofish-associated Haff disease. In contrast to previous reports that I. cyprinellus is the causative species in US cases, data indicate that all three buffalofish species are harvested but I. bubalus is most often associated with illness.

Abstract
Listeriosis can occur in susceptible populations when products with low-level contamination are distributed widely. The relationship between the number of ingested Listeria monocytogenes cells in food and the likelihood of developing listeriosis is not well understood. Data from an outbreak of listeriosis linked to milkshakes made from ice cream produced in 1 factory showed that contaminated products were distributed widely to the public without any reported cases, except for 4 cases of severe illness in persons who were highly susceptible. The ingestion of high doses of L. monocytogenes by these patients infected through milkshakes was unlikely if possible additional contamination associated with the preparation of the milkshake is ruled out. This outbreak illustrated that the vast majority of the population did not become ill after ingesting a low level of L. monocytogenes but raises the question of listeriosis cases in highly susceptible persons after distribution of low-level contaminated products that did not support the growth of this pathogen.

Abstract
Our findings do not warrant rejecting the hypothesis that outbreak and sporadic illnesses are similar. Comparing Sporadic and Outbreak Foodborne Illness Outbreak data have been used to estimate the proportion of illnesses attributable to different foods. Applying outbreak-based attribution estimates to nonoutbreak foodborne illnesses requires an assumption of similar exposure pathways for outbreak and sporadic illnesses. This assumption cannot be tested, but other comparisons can assess its veracity. Our study compares demographic, clinical, temporal, and geographic characteristics of outbreak and sporadic illnesses from Campylobacter, Escherichia coli O157, Listeria, and Salmonella bacteria ascertained by the Foodborne Diseases Active Surveillance Network (FoodNet). Differences among FoodNet sites in outbreak and sporadic illnesses might reflect differences in surveillance practices. For Campylobacter, Listeria, and Escherichia coli O157, outbreak and sporadic illnesses are similar for severity, sex, and age. For Salmonella, outbreak and sporadic illnesses are similar for severity and sex. Nevertheless, the percentage of outbreak illnesses in the youngest age category was lower. Therefore, we do not reject the assumption that outbreak and sporadic illnesses are similar.

Geospatial Mapping of Early Cases in Multistate Foodborne Disease Outbreaks: A Strategy To Expedite Identification of Contaminated Imported Produce, United States, 2006 to 2013. J Food Prot 2017; 80:1821-1831.

Abstract
From 1998 to 2008, produce-related illness outbreaks accounted for roughly one-half of reported foodborne outbreaks in the United States. In 2013, Mexico accounted for approximately 50 and 30% of the monetary value of all vegetables and fruits, respectively, imported into the United States. We used historical import data to examine the correlation between the port of entry for five implicated produce vehicles from five multistate outbreaks and the geospatial and temporal distribution of illnesses in the corresponding outbreaks in the United States. For comparison, we analyzed the geospatial and temporal distribution of cases from two U.S. multistate outbreaks associated with domestically grown produce. The geospatial distribution of illnesses in the two outbreaks linked to domestic produce differed from that of the import-related produce outbreaks. The results of our pilot study suggest that geospatial distribution of early-onset cases may be used to identify ports of entry for produce likely to be responsible for causing multistate outbreaks in the United States and that targeted sampling of produce items from these ports of entry may expedite identification of an outbreak vehicle.

Abstract
INTRODUCTION Metallosis involving the knee joint most often results from metal-on-metal contact late in the life of a failing implant following polyethylene wear. We report a case of acute metallosis following knee arthroplasty in a previously healthy 59-year old male. CASE REPORT In June 2011, the patient underwent left knee arthroplasty for severe osteoarthritis with necrosis and bone edema in the medial femoral condyle and tibial plateau. Nine months later, because of persistent pain and swelling in the joint, revision arthroplasty was undertaken along with partial synovectomy. Examination revealed pristine prosthetic implants in the absence of loose fragments of bone or glue. Synovial pathology exhibited marked chronic inflammation and hyperplasia with extensive finely granular foreign material resembling metallic debris. Laboratory analysis of synovium revealed a predominance of iron, the principal component of the saw blades. CONCLUSION We hypothesize the patient experienced acute metallosis resulting from deposition of metallic fragments from three saw blades used during arthroplasty. We believe the increased density of the patient's bone that required use of multiple blades may have resulted, in part, from heavy lifting the patient partook in during the two years preceding arthroplasty.

Abstract
OBJECTIVE Liver disease is a potential complication from using dietary supplements. This study investigated an outbreak of non-viral liver disease associated with the use of OxyELITE Pro(TM), a dietary supplement used for weight loss and/or muscle building. METHODS Illness details were ascertained from MedWatch reports submitted to the U.S. Food and Drug Administration (FDA) describing consumers who ingested OxyELITE Pro alone or in combination with other dietary supplements. FDA's Forensic Chemistry Center analyzed samples of OxyELITE Pro. RESULTS From February 2012 to February 2014, FDA received 114 reports of adverse events of all kinds involving consumers who ingested OxyELITE Pro. The onset of illness for the first report was December 2010 and for the last report was January 2014. Thirty-three states, two foreign nations, and Puerto Rico submitted reports. Fifty-five of the reports (48%) described liver disease in the absence of viral infection, gallbladder disease, autoimmune disease, or other known causes of liver damage. A total of 33 (60%) of these patients were hospitalized, and three underwent liver transplantation. In early 2013, OxyELITE Pro products entered the market with a formulation distinct from products sold previously. The new formulation replaced 1,3-dimethylamylamine with aegeline. However, the manufacturer failed to submit to FDA a required "new dietary ingredient" notice for the use of aegeline in OxyELITE Pro products. Laboratory analysis identified no drugs, poisons, pharmaceuticals, toxic metals, usnic acid, N-Nitroso-fenfluramine, pyrrolizidine alkaloids, aristocholic acid, or phenethylamines in the products. CONCLUSIONS Vigilant surveillance is required for adverse events linked to the use of dietary supplements.

Abstract
The present study was conducted to evaluate the level of food safety protection provided to consumers of Grade "A" milk and milk products in the United States by the National Conference on Interstate Milk Shipments (NCIMS) Grade "A" Milk Safety Program through its implementation and enforcement of the U.S. Grade "A" Pasteurized Milk Ordinance (PMO). The number of reported illnesses associated with Grade "A" milk and milk products in the United States was obtained from state and federal agencies and published articles. The consumption of Grade "A" milk and milk products in the United States was estimated from food consumption survey data for individuals. The level of food safety protection was measured quantitatively using the metric of annual illness attack rate. During a 15-year period (1999 through 2013), the estimated annual illness attack rate was 0.41 reported illnesses per 1 billion exposures (estimated using person-day intake data) or 0.52 reported illnesses per 1 billion lb (454 million kg) of Grade "A" milk and milk products consumed. Food safety protection provided to consumers of Grade "A" milk and milk products by the NCIMS through its implementation and enforcement of the PMO is important given the common consumption of Grade "A" milk and milk products in the United States.

Abstract
Recalls of foods contaminated with pathogens help reduce the transmission of infectious diseases. Here, we summarize the number and nature of foods recalled as a result of microbiological contamination, classified by the U.S. Food and Drug Administration for the period 1 October 2002 through 30 September 2011. Microbiological contamination accounted for 1,395 (42%) of 3,360 recalls of food during this period. Nuts and edible seeds, followed by fishery-seafood products and spices, were the types of products most commonly recalled for microbiological contamination. Salmonella contamination accounted for the greatest number of food products recalled due to microbiological contamination, and was the pathogen most often linked to reported outbreaks involving recalled food products.

Abstract
Using data from the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) from 1996 to 2001, we compared the clinical features of diarrhea in patients with stool specimens yielding only A. hydrophila (189 patients; 1.4% of 13,970 patients screened) or P. shigelloides (253 patients) compared to patients with sole V. cholerae non-O1 infection (99 patients) or V. parahaemolyticus infection (126 patients). Patients exhibited similar frequencies of fever (temperature >37.8°C), stools characterized as watery, and stools containing visible mucus. Dehydration was observed more often among patients with V. parahaemolyticus or V. cholerae non-O1 infection. Compared to patients infected with V. parahaemolyticus, those with A. hydrophila, P. shigelloides, or V. cholerae non-O1 infection were less likely to report visible blood in the stool and, on microscopic examination, less likely to exhibit stool red blood cell and white blood cell counts exceeding 20 cells per high power field. The proportion of patients reporting subjective cure at the time of discharge was significantly smaller for those infected with V. parahaemolyticus. These findings suggest that A. hydrophila and P. shigelloides produce diarrheal disease that is less severe than that resulting from infection with V. cholerae non-O1 or V. parahaemolyticus.

Abstract
Case-control studies conducted during a multistate outbreak of Salmonella enterica serotype Saintpaul infections in 2008 revealed associations between illness and the consumption of jalapeño peppers, Serrano peppers, and tomatoes. Traceback investigations of implicated jalapeño and Serrano peppers led to farms in Tamaulipas and Nuevo León, Mexico. We conducted a novel analysis of a U.S. Food and Drug Administration database of tomatoes and jalapeño and Serrano peppers imported from Mexico during the first half of 2008 to describe the temporal and spatial flow of these items into the United States. Shipments of all three produce items followed a south-to-northwest corridor; 87% of peppers and 97% of tomatoes produced in Mexican states located west of the Sierra Madre Occidental were transported to ports in California and Arizona, and 90% of peppers and 100% of tomatoes produced in states east of the Sierra Madre Occidental were transported to ports east of Arizona. We found a significant correlation between state-specific infection rates and quantity of imported Mexican jalapeño and Serrano peppers to U.S. states by the first-level consignee but not for imported Mexican tomatoes. We localized production regions of interest by finding that quantities of both peppers and tomatoes imported from the states of Nuevo León and Tamaulipas were correlated with infection rates. In outbreaks possibly caused by agricultural commodities, analysis of import databases may foster a better understanding of growing seasons, harvest sites, shipment itineraries, and consignee destinations, thereby adding valuable insight into findings derived from epidemiologic studies.

Abstract
OBJECTIVES Muscletech Hydroxycut (Iovate Health Sciences Research, Oakville, Ontario, Canada) was a popular weight-loss supplement that was recalled by the manufacturer in May 2009 on the basis of reports of hepatotoxicity associated with this supplement. We sought to characterize the clinical presentation of Hydroxycut-associated liver injury and to adjudicate these cases for causal association with Hydroxycut. METHODS We assessed the causality and grading of severity of liver injury using methodology developed by the Drug-Induced Liver Injury Network (DILIN) study. RESULTS Eight patients who developed liver injury after taking Hydroxycut treated at different medical centers were identified. All were hospitalized, and three of eight patients required liver transplantation. Nine other cases with adequate clinical information were obtained from the FDA MedWatch database, including one fatal case of acute liver failure. Usual symptoms were jaundice, fatigue, nausea, vomiting, and abdominal pain. Most patients exhibited a hepatocellular pattern of injury. Adjudication for causality revealed eight cases as definite, five highly likely, two probable, and two were considered to be possible. CONCLUSIONS Hydroxycut has been clearly implicated as a cause for severe liver injury that may lead to acute liver failure and death. Weight-loss supplements represent a class of dietary supplements that should be regarded as capable of causing severe hepatic toxicity when the usual causes of identified liver injury cannot be otherwise elucidated.

Abstract
From 1986 to 2006, the incidence of listeriosis in the United States dropped from approximately seven to three cases per million population, a reduction that most likely reflects the joint efforts of industry, government, consumers, and academia. Herein, we describe the U.S. Food and Drug Administration (FDA) strategy over the past three decades to combat listeriosis. Specifically, we discuss early actions taken to address outbreaks during the 1980s, policy decisions regarding the presence of Listeria monocytogenes in FDA-regulated foods, FDA compliance programs with L. monocytogenes components, enforcement actions to remove L. monocytogenes-contaminated products from the market (i.e., recalls) or to prevent entry of such products into the market (i.e., import detentions and refusals), research milestones, outreach and education efforts, and selected special projects. Evolving demographic trends in the United States may pose a challenge to further reduction of the incidence of listeriosis.

Abstract
BACKGROUND Following the marketing ban of ephedra-containing supplements in April 2004, many manufacturers substituted the herb Citrus aurantium for ephedra and marketed the products as "ephedra-free" supplements. Extracts of C. aurantium contain synephrine, a sympathomimetic alkaloid. OBJECTIVE To determine the prevalence of consumption of dietary supplements containing C. aurantium in California during 2004. METHODS We used the 2004 California Behavioral Risk Factor Surveillance Survey to determine the prevalence of consumption of dietary supplements containing C. aurantium in California during 2004. RESULTS Two percent (n = 70) of the 4140 survey respondents reported taking a dietary supplement containing C. aurantium in the previous year. Reasons stated included energy enhancement, weight loss, and appetite suppression. Compared with nonusers, users were more likely to report being single, aged 18-34 years, and Hispanic; consuming 3 or more alcoholic drinks on days that they imbibed; and having a heavier body mass index. Among the 5 users who reported experiencing an adverse event that they attributed to the supplement, 3 indicated that the severity was mild. CONCLUSIONS Given that supplements containing ephedra were banned in April 2004, the results from this study may serve as a baseline estimate against which future studies of the use of C. aurantium products may be compared.

Abstract
From 1980 to 2000, the annual per capita consumption of spices in the United States increased by 60% (from 1.0 to 1.6 kg per person per year). Although spices are known to harbor various molds, fungi, and bacteria, relatively few reports have documented this group of foods as the cause of human illness. In recent years, however, the U.S. Food and Drug Administration (FDA) has noted an increased number of recalls of dried spices due to bacterial contamination. Accordingly, we reviewed spice recalls that took place in the United States from fiscal years 1970 to 2003. During the study period, the FDA monitored 21 recalls involving 12 spice types contaminated with bacterial pathogens; in all but one instance, the recalled spices contained Salmonella. Paprika was the spice most often involved in the recalls. A wide variety of countries were the source of the recalled spices. Using data from the Centers for Disease Control and Prevention National Salmonella Surveillance System, we were unable to discern any increases in the reported incidence of laboratory-confirmed salmonellosis in states that received spices contaminated with selected rare Salmonella serotypes. A variety of effective methods exist to disinfect spices, procedures that have attained increased importance given the frequent use of spices in ready-to-eat foods and the potential for contaminated spices to cause widespread outbreaks.

Abstract
Sulfite-sensitive individuals can experience adverse reactions after consuming foods containing sulfiting agents (sulfites), and some of these reactions may be severe. In the 1980s and 1990s, the U.S. Food and Drug Administration (FDA) acted to reduce the likelihood that sulfite-sensitive individuals would unknowingly consume foods containing sulfites. The FDA prohibited the use of sulfites on fruits and vegetables (except potatoes) to be served or presented fresh to the public and required that the presence of detectable levels of sulfites be declared on food labels, even when these sulfites are used as a processing aid or are a component of another ingredient in the food. In the present study, data from FDA recall records and adverse event reports were used to examine the current status of problems of sensitivity to sulfites in foods. From 1996 through 1999, the FDA processed a total of 59 recalls of foods containing undeclared sulfites; these 59 recalls involved 93 different food products. Fifty (55%) of the recalled products were classified as class I, a designation indicating that a consumer reasonably could have ingested > or = 10 mg of undeclared sulfites on a single occasion, a level that could potentially cause a serious adverse reaction in a susceptible person. From 1996 through mid-1999, the FDA received a total of 34 reports of adverse reactions allegedly due to eating foods containing undeclared sulfites. The average of 10 reports per year, although derived from a passive surveillance system, was lower than the average of 111 reports per year that the FDA received from 1980 to 1987, a decrease that may have resulted in part from FDA regulatory action.

Abstract
BACKGROUND Food recalls can play a role in preventing or reducing the number of allergic reactions that may occur after a product containing an undeclared allergen has been introduced into commerce. OBJECTIVE We sought to summarize the US Food and Drug Administration's records of recalls classified for fiscal year 1999 involving foods containing undeclared allergens. METHODS Food and Drug Administration food recall records were reviewed for fiscal year 1999 to identify recalls that occurred because of the undeclared presence of one or more of the following allergens: milk, eggs, fish, wheat, crustacean shellfish, tree nuts, peanuts, and soy. Each record was reviewed to determine the recalled product, the undeclared allergen present, the reason for recall, and reported adverse events. RESULTS Of 659 total food products classified for recall during fiscal year 1999, 236 (36%) products were recalled because they contained one or more undeclared allergens. Consumers were the party most often responsible for identifying that an undeclared allergen was present in a product (56% of recalled products). A total of 34 consumers reported allergic reactions after consumption of the recalled products. Three principal factors contributed to the presence of undeclared allergens in the recalled products: ingredient-statement omissions and errors (51% of all recalled products); manufacturing equipment cross-contact (40%); and errors by ingredient suppliers or manufacturing firm employees (5%). CONCLUSION The presence of undeclared allergens in food products represents one of the more common reasons for food-product recall in the United States. A number of well-recognized allergens may be introduced into foods as a result of several different factors.

Abstract
OBJECTIVE To study the long-term outcome of adverse effects reported by persons who used a commercial hair-straightening product known as the Rio Hair Naturalizer System (World Rio Corporation). DESIGN Survey of individuals who contacted the Food and Drug Administration in 1994 and 1995 to report adverse effects linked to using the product. SETTING Persons residing in the United States. PATIENTS A total of 464 (59% of 790 eligible) patients who returned a completed questionnaire. MAIN OUTCOME MEASURES Adverse effects associated with using the Rio Hair Naturalizer System products (neutral or color enhancer). RESULTS Ninety percent of respondents were African American women between the ages of 15 and 55 years. The most common complaints associated with the use of the products were hair breakage and/or hair loss, reported by 95% of respondents. Three quarters of those experiencing hair loss reported losing 40% or more of their original hair. The median time between the loss of original hair and the growth of new hair was 8 months; however, 40 (9%) respondents reported having no new growth at the time of completing the survey, some 2 years after using the product. When mixed according to package instructions, the mean pH of a sample of 20 neutral product kits tested was 1.39 (range, 1.1-3.15). For the 21 color-enhancer products tested, the mean pH was 2.82 (range, 2. 29-3.08). CONCLUSIONS A nationwide outbreak of alopecia and scalp injuries involving tens of thousands of women (and some men) occurred following the marketing of a chemical hair-relaxing product. Most of those affected reported substantial hair loss, with a majority indicating growth of new hair that was abnormal in both quantity and quality.

Abstract
In the U.S., food product recalls serve as an important intervention in stemming the consumption of food products contaminated with infectious disease agents. We summarize the number and nature of foods and cosmetics recalled as a result of microbial contamination reported to the U.S. Food and Drug Administration (FDA) for the period 1 October 1993 through 30 September 1998. During this period, microbial contamination of food and cosmetic products was the leading cause for recalls, accounting for a total of 1,370 recalls (36% of all products recalled). Listeria monocytogenes accounted for the greatest number of food products recalled because of microbial contamination, whereas Pseudomonas aeruginosa was the most common microbe associated with recalls of cosmetic products. Dairy products, followed by seafood and pastry items, were the types of products most often associated with recalls due to microbial contamination. The FDA was the entity most often responsible for detecting microbial contamination of foods and cosmetics (33% of all such recalls), followed by state regulatory agencies (24%), and manufacturers/retailers (21%). Nineteen percent of recalls were associated with at least one reported case of illness. Salmonella was the pathogen most often implicated in reports of illness associated with these recalled products.

Abstract
BACKGROUND Raw shellfish-associated Vibrio vulnificus septicemia, with a case-fatality rate of nearly 50%, occurs most commonly in immunocompromised patients or those with liver disease. METHODS Sixty patients with renal disease treated with hemodialysis at The George Washington University and awaiting renal transplantation completed an initial survey that assessed their raw shellfish eating habits and knowledge regarding the pathogen V. vulnificus. Patients were then given educational materials describing the risks of eating raw shellfish and, one month later, completed a second survey that assessed their knowledge retention and intent to eat or not eat raw shellfish in the future. RESULTS Sixty of 68 (88%) eligible patients completed the survey. Forty-eight percent of patients reported having eaten raw shellfish after being diagnosed with kidney disease, with the highest rates reported among subjects < or = 49 years old and subjects with more than a high school education. Prior to receiving the educational materials, no patient had heard of the pathogen V. vulnificus. Three quarters of patients reported never having been advised by a physician to avoid eating raw shellfish. One month after reading the educational materials, 75% of patients said they would refrain from eating raw shellfish in the future. CONCLUSIONS In view of their immunocompromised status, patients with end-stage renal disease should be counseled to abstain from eating raw shellfish.

Abstract
Patients with infected aneurysms discharged from Department of Veterans Affairs hospitals during fiscal years 1986 to 1990 were identified using International Classification of Diseases codes to determine the proportion of patients infected with Salmonella. Twenty-three patients with infected aneurysms were identified. All patients were males; the median age was 63 years. A Gram-positive organism was recovered from 16 patients (70%), a Gram-negative organism from 6 patients (26%), and a fungus from 1 patient. Three patients, all with aneurysms of the abdominal aorta, were infected with Salmonella. Overall, the vessels most often involved included arteries of the extremities (10 patients) and the abdominal or thoracic aorta (9 patients). An increased incidence of nontyphoidal salmonellosis in the United States during the last few decades, along with an aging of the U.S. population, suggests that Salmonella can be expected to maintain a niche in the bacteriology of infected aneurysms.

Abstract
With increasing age there is an increase in both the incidence as well as the mortality due to many infectious illnesses, and foodborne infectious disease is no exception. A review of the pertinent literature identified studies concerning foodborne disease caused by infectious agents in the elderly, as well as those factors that could account for the increase in morbidity and mortality seen in the elderly due to foodborne infections. The published information suggested that the basis for the increased incidence, severity and risk of death of many foodborne infectious diseases in elderly persons is related to factors such as reduced gastric acidity, a higher prevalence of underlying medical disorders (co-morbidity factors), and immune system changes that result in a less effective host defense against infectious agents. The greater risk of foodborne disease experienced by elderly persons results from the contribution of non-immune and immune mediated factors. Due to the growing number of persons over the age of 65 years in the United States, foodborne disease in this age group will continue to be an important source of illness and death in the population.

Abstract
BACKGROUND Although peanuts and peanut butter are well recognized as food allergens, few reports describe allergic reactions associated with eating peanut flour. OBJECTIVE To describe an allergic reaction that occurred in a peanut-sensitive woman who ate undeclared peanut flour that was part of a flavor ingredient contained in a dry soup mixture, and to estimate the amount of peanut protein the patient ingested. METHODS The patient was interviewed, medical records from her emergency room visit were reviewed, and the manufacturer of the soup mix was investigated to ascertain the proportion of the soup mix constituted by the undeclared peanut flour. RESULTS Minutes after ingesting the soup, a 33-year-old woman experienced a systemic allergic reaction. She was treated successfully in the emergency room with intravenous fluids, corticosteroids, and diphenhydramine. Investigation of the soup manufacturer revealed that undeclared peanut flour was a component of a flavoring ingredient in the soup. Based on the concentration of peanut flour in the flavoring, we estimated the patient ate approximately 45 mg of peanut protein. CONCLUSIONS Inadvertent ingestion of peanut flour by peanut-sensitive individuals may lead to systemic allergic reactions.

Abstract
OBJECTIVES The authors sought to determine the prevalence of raw milk consumption in California--the largest producer of certified raw milk in the United States--and to describe the demographic and behavioral characteristics of raw milk consumers in that state. METHODS The authors analyzed responses to questions on the 1994 California Behavioral Risk Factor Surveillance System Survey that asked respondents about whether they drank raw milk, the amount consumed, the reason for drinking raw milk, and where raw milk was most often obtained. RESULTS Among 3999 survey respondents, 3.2% reported drinking raw milk in the previous year. Raw milk drinkers were more likely than nondrinkers to be younger than age 40, male, and Hispanic and to have less than a high school education. CONCLUSIONS Raw milk continues to be consumed by some residents of California despite the documented hazards associated with this dietary practice.

Abstract
Recalls of foods and cosmetics from the marketplace are an expeditious and effective method of removing violative products, particularly those that present a danger to health. Recalls are undertaken through a cooperative effort by industry and the U.S. Food and Drug Administration (FDA). Foods and cosmetics recalled from the period 1 October 1991 through 30 September 1992 were reviewed to determine the kinds of products recalled and the reasons for recall. A total of 230 recalls, involving 569 foods and cosmetics, occurred during the study period. Twenty-eight percent of the recalls were designated class I, defined as a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences. The problems for which foods or cosmetics were most often recalled were misbranding and microbial contamination (37% and 25% of recalls, respectively). A recognized illness or injury was reported to have occurred in association with 32 food products and one cosmetic. This study indicates that recalls of foods and cosmetics are common and that various groups, including industry, consumers, state regulatory agencies, and the FDA, recognize problems leading to recall.

Abstract
The epidemiology of 690 Vibrio infections reported in Florida during 1981-1993 is described. Most infections resulted in one of three clinical syndromes: gastroenteritis (51%), wound infections (24%), or primary septicemia (17%). Case-fatality rates were 1% for gastroenteritis, 5% for wound infections, and 44% for primary septicemia. While gastroenteritis had little seasonal variation, 91% of primary septicemias and 86% of wound infections occurred from April through October, mostly due to the seasonality of Vibrio vulnificus and Vibrio parahaemolyticus infections. Infected wounds were largely a result of occupational activities around seawater. Some 68% of gastroenteritis cases and 83% of the primary septicemias were associated with raw oyster consumption. Preexisting liver disease was present in 48% of patients with primary septicemia and was associated with a fatal outcome in both wound infections (relative risk [RR], 28.3; 95% confidence interval [CI], 6.3-127.5; P < .0001) and primary septicemia (RR, 1.9; 95% CI, 1.2-3.1; P < .01).

Abstract
Although not well quantified, a portion of food-borne illnesses results from voluntary behaviors that are entirely avoidable, such as eating raw foods of animal origin or engaging in unsafe food preparation practices. A telephone survey of 1,620 respondents was conducted to assess the prevalence of selected self-reported food consumption and preparation behaviors associated with increased risks of food-borne illness and the demographic characteristics related to such behaviors. The percentages of survey respondents who reported consuming raw foods of animal origin were 53%, raw eggs; 23%, undercooked hamburgers; 17%, raw clams or oysters; and 8%, raw sushi or ceviche. A fourth of the respondents said that after cutting raw meat or chicken, they use the cutting board again without cleaning it. Safer food consumption and preparation behaviors were consistently reported by persons who were female, were at least 40 years old, and had a high-school education or less. These findings suggest that risky food consumption and preparation behaviors are common in the United States and that educational campaigns aimed at changing these behaviors may need to be targeted to specific groups of persons.

Abstract
We used the 1992 California Behavioral Risk Factor Surveillance System to study the prevalence of raw shellfish consumption in California and the demographic and behavioral characteristics of raw shellfish consumers. We used the logistic regression analysis of the weighted survey data with PC SAS and SUDAAN to adjust for the effects of age and gender. Twenty-three percent of the respondents in the survey reported that they ate raw shellfish; one third of these reported eating raw shellfish once a month. Higher prevalences of raw shellfish consumption were reported by men, persons 18-49 years old, those with income above $25,000 and education beyond high school than by women, individuals older than 49 years, and those with an income of $25,000 or less per year and 12 or fewer years of school. A higher percentage of persons with liver disease, stomach surgery, and a history of chronic alcohol drinking reported consumption of raw shellfish than did individuals without liver disease, previous stomach surgery, or a history of alcohol abuse. After adjustment for gender and age, those who reported acute (P < .01) and chronic (P < .01) drinking and driving while intoxicated (P < .01) were more likely to report consumption of raw shellfish. Two variables (lack of seat belt usage [P = 2] and cigarette smoking [P = .13]) were not significantly associated statistically with raw shellfish consumption.

Abstract
The 1992 Rhode Island Behavioral Risk Factor Surveillance System was used to assess self-reported health behaviors of consumers of finfish and raw shellfish. We hypothesized that consumers of finfish, foods considered to be healthy, were more likely than nonconsumers of finfish to partake in health-promoting behaviors. Similarly, we postulated that consumers of raw molluscan shellfish, foods linked to an elevated risk of acquiring various illnesses, were more likely than nonconsumers of raw-shellfish to partake in risk-taking behaviors. Finfish eaters were significantly more likely than abstainers to report recent exercise, efforts to lose weight, periodic monitoring of serum cholesterol, and not currently being smokers. Raw shellfish eaters were significantly more likely than abstainers to report recent acute and chronic alcohol consumption. The results suggest that inquiry into dietary patterns may be an avenue for exploring other health behaviors.

Abstract
Raw oysters harvested from Apalachicola Bay, FL, and purchased from a retail outlet in Tallahassee, FL, were tested monthly from March 1989 through March 1990 for the presence of Vibrio species. We studied the temporal relationship between Vibrio levels found in these oysters and the incidence of raw oyster-associated Vibrio illnesses with onset dates in 1989-1990 among persons living in counties located adjacent to or near Apalachicola Bay. Five of the six Vibrio species implicated in raw oyster-associated gastroenteritis or septicemia in the study area during 1989-1990 were recovered from the retail raw oysters. With the exception of Vibrio vulnificus , which was recovered during the warmest months, recovery of other Vibrio species from oysters was distributed widely throughout the year. Thirty-seven patients in the study area with 39 Vibrio infections with onset of illness from January 1989 through December 1990 were reported to the Florida Department of Health and Rehabilitative Services. Thirty-three (89%) of these patients reported eating raw oysters during the week before onset of illness and experienced gastroenteritis (32 patients) or septicemia (1 patient).

Abstract
As part of its effort to assure a safe food supply, the Food and Drug Administration maintains a passive surveillance system for the reporting and followup of complaints related to food items. This surveillance system, called the Complaint Reporting System, records and investigates consumer complaints about the quality of a specific food item, its packaging, or unexpected effects following consumption of the food. This study, relying on data gathered from the 2,726 reports of discovery of a foreign object in a food item during fiscal year 1989, develops a profile of consumer complaints, focusing on those associated with resultant injury or illness. Fourteen percent of all reported cases of foreign object exposure cited resultant illness or injury. The most common foreign object reported in food is glass, and the most common injury is a laceration or abrasion of soft tissues of the perioral area, including the throat. There was a disproportionate representation of children younger than age 3 years with documented illness or injury. Only 3 percent of the complaints came from attending health professionals; 82 percent were self-reported. Practitioner awareness of the system is limited primarily because literature in this area is scant. The collection and investigation of reports of foreign objects in food are important because such reports provide early warnings of potential problems with manufacturers' food items. Although data suggest that severe injury from foreign object ingestion is rare, continued monitoring is warranted. Health professionals are encouraged to report such injuries through the existing system.

Abstract
Limited data indicate that drinking alcoholic beverages along with eating food contaminated with Shigella or Salmonella decreases the risk and/or the severity of illness. No such study has been reported following exposure to a viral pathogen. During an oyster-borne outbreak of hepatitis A, we studied the effect of ingestion of alcoholic beverages concomitant with consumption of contaminated oysters. The analysis was restricted to 51 cases and 33 controls who had consumed the implicated raw oysters. After controlling for potential confounders, we found a protective effect for beverages that have an alcohol concentration of greater than or equal to 10% (odds ratio = 0.1, 95% confidence interval = 0.02-0.9), but not for beverages with an alcohol concentration of less than 10% (odds ratio = 0.7, 95% confidence interval = 0.2-2.9).

STUDY OBJECTIVES To determine the incidence of needlestick injury among paramedics working in Florida during 1987, to describe the circumstances surrounding such injuries, and to assess the hepatitis B vaccination status of this group. DESIGN Survey of a systematic random sample of paramedics using a self-administered questionnaire. SETTING Florida. TYPE OF PARTICIPANTS Paramedics. MAIN RESULTS A completed questionnaire was returned by 300 of 500 paramedics (60%) who received the mailed questionnaire. Sixty-nine paramedics (23%) reported a total of 110 needlestick injuries. More than one third of injuries occurred in conjunction with recapping needles. Almost 62% of reported injuries could have been prevented had proper needle disposal technique been used. Sixty-two percent of paramedics reported having had at least one dose of the hepatitis B vaccine. Sixty-five percent of the unvaccinated paramedics said they would take the hepatitis B vaccine if it was offered free. CONCLUSION The majority of needlestick injuries among paramedics in Florida could be prevented with proper needle disposal. Offering the hepatitis B vaccine at no charge to paramedics in Florida could increase the vaccination rate substantially.

We used the 1988 Behavioral Risk Factor Surveillance System in Florida to determine the prevalence of consumption of raw oysters, a vehicle implicated in the transmission of several pathogens. One-third of survey respondents reported ever eating raw oysters. The prevalence was higher for persons 18-49 years old and for males, and, when controlled for age and sex, for persons who reported being cigarette smokers or acute or chronic alcohol drinkers, and driving while intoxicated.

Abstract
BACKGROUND In August 1988 we investigated a multistate outbreak of hepatitis A caused by Panama City, Florida, raw oysters. METHODS Cases of hepatitis A (HA) with onset in July-August 1988 were identified among persons who ate seafoods harvested in the coastal waters of Panama City, Florida. We conducted a case-control study, using eating companions of case-patients, and calculated attack rate (AR) per 1000 dozen raw oysters served. Enzyme immunoassay (EIA) and a polymerase chain reaction (PCR) technique were performed on samples of raw shellfish obtained from Panama City coastal waters. RESULTS Sixty-one case-patients were identified in five states: Alabama (23), Georgia (18), Florida (18), Tennessee (1), and Hawaii (1). We found an increased risk of HA for raw oyster eaters (odds ratio = 24.0; 95% confidence interval = 5.4-215.0; P less than .001). The AR of HA in seafood establishments was 1.9/1000 dozen raw oysters served. The EIA and PCR revealed HA virus antigen and nucleic acid in oysters from both unapproved and approved oyster beds, in confiscated illegally harvested oysters, and in scallops from an approved area. CONCLUSIONS The monitoring of coastal waters and the enforcement of shellfish harvesting regulations were not adequate to protect raw oyster consumers. More emphasis should be placed on increasing public awareness of health hazards associated with eating raw shellfish.

Abstract
In the period 1981-1988, 333 cases of bacteriologically confirmed Vibrio illness were reported in Florida adult residents. A total of 197 patients (59.2%) had consumed raw oysters the week prior to becoming ill, and among those 197, 38 (19.3%) had a liver disease, 13 (6.6%) had past gastric surgery, and 15 (7.6%) were diabetic. To calculate a population-based incidence rate, the authors obtained prevalence estimates of annual raw oyster consumption, liver disease, previous gastric surgery, and diabetes through a random telephone survey of Florida adult residents and applied them to the January 1985 Florida population. The estimated age-standardized annual incidence of Vibrio illness per million was 95.4 for raw oyster eaters with liver disease, 9.2 for raw oyster eaters without liver disease, and 2.2 for non-raw oyster eaters. Those with prior gastric surgery had a moderately increased risk of Vibrio illness. The annual incidence for Vibrio septicemia was 82.8 for raw oyster eaters with liver disease, 2.0 for raw oyster eaters without liver disease, and 0.4 for non-raw oyster eaters. While estimates on which these data are based are subject to a number of potential biases, this is the first study to provide estimates of the risk of Vibrio illness in raw oyster eaters, and it supports the recommendation that raw oyster consumption should be avoided by persons with liver disease.
