Abstract
Celiac disease, wheat sensitivity, and allergy represent three different reactions, which may occur in genetically predisposed individuals on the ingestion of wheat and derived products with various manifestations. Improvements in the disease diagnostics and understanding of disease etiology unveiled that these disorders are widespread around the globe affecting about 7% of the population. The only known treatment so far is a life-long gluten-free diet, which is almost impossible to follow because of the contamination of allegedly "gluten-free" products. Accidental contamination of inherently gluten-free products could take place at any level from field to shelf because of the ubiquity of these proteins/grains. Gluten contamination of allegedly "gluten-free" products is a constant threat to celiac patients and a major health concern. Several detection procedures have been proposed to determine the level of contamination in products for celiac patients. The present article aims to review the advantages and disadvantages of different gluten detection methods, with emphasis on the recent technology that allows identification of the immunogenic-gluten peptides without the use of antibodies. The possibility to detect gluten contamination by different approaches with similar or better detection efficiency in different raw and processed foods will guarantee the safety of the foods for celiac patients.

Abstract
Mercury (Hg) in fish and aquatic products is a potential threat to human health and international trade, and guidelines of international advisory bodies are established for assessing Hg in these foods. As fish are the most consumed animal protein in Sri Lanka, this assessment summarises for the first-time total mercury concentrations in Sri Lankan marine and freshwater fish, invertebrates, aquatic plants, and fisheries products. It reveals that Hg levels in fish and other edible aquatic species are mostly below the published safety limits, except for certain top trophic level fish (swordfish, tuna, marlin). The review also highlights gaps in Sri Lankan Hg assessments such as a total lack of data for methyl‑mercury in these aquatic species and food products. This data compilation and assessment will serve as an initial baseline for comparison with results from future monitoring and research studies in Sri Lanka while adding to the world-wide Hg database.

Abstract
High bioavailability of man-made pollutants in marine environments raises serious concern regarding the safety of seafood. In the present study, the presence, trophic transfer, and risks of polycyclic aromatic hydrocarbons (PAHs), and potentially toxic elements (PTEs) in 170 benthic marine organisms (87 prawn; 28 crab; 55 fish) from the Persian Gulf were investigated. Among investigated species, E. coioides displayed the lowest level of metal pollution index (MPI), while P. armatus and P. semisulcatus showed the highest level of MPI and total PAHs, respectively. Principal component biplot exhibited a significant association of PTEs (except Hg) and PAHs in less motile benthic species. The results of trophic transfer investigation revealed that PTEs (except Hg) and PAHs were not biomagnified in the studied organisms through diet. However, Hg biomagnification factors greater than 1 indicated trophic transfer of mercury. In order to gain nutritional benefits of seafood, consumption of two fish/prawn meals/week for adults (except vulnerable groups such as pregnant women) and one fish/prawn meals/week for children is recommended. However, lifelong consumption of crabs (P. armatus) may threaten human health. In addition, the maximum allowable fish consumption rate (CRlim) for studied fish is 120 g fish/day for adults and 30 g fish/day for children. In the case of prawns, the safe dose is 30 and 10 g prawns/day for adults and children, respectively.

Abstract
It is estimated that approximately 200 million people are exposed to arsenic levels above the World Health Organization provisional guideline value, and various agencies have indicated the need to reduce this exposure. In view of the difficulty of removing arsenic from water and food, one alternative is to reduce its bioavailability (the amount that reaches the systemic circulation after ingestion). In this study, dietary components [glutathione, tannic acid, and Fe(III)] were used to achieve this goal. As(III) or As(V) (1 mg/kg body weight) was administered daily to BALB/c mice, along with the dietary components, for 15 days. The results confirm the efficacy of Fe(III) and glutathione as reducers of arsenic bioavailability and tissue accumulation. Also, these treatments did not result in reductions of Ca, K, P, and Fe contents in the liver. These data suggest that use of these two compounds could be part of valid strategies for reducing inorganic arsenic exposure in chronically exposed populations.

Abstract
Production of polychlorinated biphenyls (PCB) was banned in the US in 1970s. However, susceptible populations especially those living at/around the contaminated sites continue to be at a risk of elevated exposure to PCBs because information about the contamination (of the environment) and its associated health risks may not reach these populations. A recent study found the second highest concentration of PCBs ever recorded worldwide in the sediment samples of Guánica Bay, located in the southwestern part of Puerto Rico. PCB levels in fish from the bay were also higher than the tolerance limit of Food and Drug Administration (FDA), which motivated this research to initiate a school-based campaign to bring community awareness about the contamination of the bay and engage students in preventive strategies to reduce their exposure to PCBs. Surveys before and after the campaign were administered in the high school as well as in the communities of Guánica Municipality. The analyses of the survey data suggest that the campaign was effective in bringing awareness among schoolchildren (6.6% before versus 69.7% after the campaign; χ2 ~ 60.4; p < 0.001) and strategies to reduce PCB exposure and its toxicity such as removing adipose tissues from seafood/fish and exercising. In the community, there was a significant decline in the consumption of seafood/fish harvested from the bay after the campaign (54.6% before versus 33% after the campaign; χ2 ~ 10.85; p < 0.001). However, the awareness did not result in significant behavior modifications among schoolchildren, such as avoiding swimming and fishing in the bay. Given hazardous levels of PCBs and some students use the bay for various purposes, including one-third of community members still use seafood/fish harvested from the bay, attention of different stakeholders is warranted for clean-up efforts as well as engaging children and communities in PCB exposure avoidance strategies.

Abstract
Assessing the safety of genetically engineered crops includes evaluating the risk (hazard and exposure) of consuming their newly expressed proteins. The dicamba monooxygenase (DMO) protein, introduced into soybeans to confer tolerance (DT) to dicamba herbicide, was previously characterized and identified to pose no food or feed safety hazards. Most agricultural commodities (e.g., soybeans, maize) enter the food supply after processing methods that can include exposure to high temperatures, harsh solvents or pH extremes that can adversely impact the structure and function of proteins. To understand the likelihood of exposure to DMO in foods from DT soy, enzymatically active and/or immunodetectable forms of DMO were measured in pilot-scale productions of two soy foods (soymilk and tofu), and eight processed fractions (full fat flour, inactivated full fat flour, defatted flour, toasted meal, protein isolate, protein concentrate, crude lecithin, and refined, bleached and deodorized oil). Western blot analysis detected DMO in tofu and in five of the eight processed fractions. DMO activity was not detected in either soymilk or tofu, nor in six of the eight processed fractions. Therefore, many commercial soy processing methods can denature and/or degrade introduced proteins, like DMO. Although the DMO protein has shown no evidence of hazard, this study demonstrates that processing further reduces any food or feed risk by limiting dietary exposure to intact DMO protein.

Abstract
Reutilization of putrescible municipal solid wastes (MSW) in agriculture can provide valuable plant nutrients. However, it may pose serious noncarcinogenic health risks for a human when contaminants, especially the heavy metals in MSW, end up in plants through the waste-soil-plant continuum. This study examined the effects of composting methods viz. aerobically (AC), anaerobically (ANC), and aerobic-anaerobically (AANC) composted MSW material on (i) fertilizer value: vegetable yield, nitrogen (N) mineralization, and apparent N recovery (ANR); and (ii) associated health risks: selected heavy metal concentration, daily intake of metals (DIM), health risk index (HRI), hazard index (HI), and target hazard quotient (THQ) when applied to a loamy soil. All the aforementioned compost materials were incorporated into the sandy loam soil filled in pots and carrot and spinach were cultivated for 85 and 90 days, respectively. After soil application, between 51 and 56% of the applied organic N was mineralized from ANC material, while the values in case of AC and AANC were 26-31% and 34-40%, respectively. Consequently, dry matter yield and vegetable N uptake from composts were in the order ANC > AANC > AC (P < 0.05). Further, vegetable ANR was the highest from ANC (56 and 56%) than AANC (42 and 45%), and AC (30 and 33%) for spinach and carrot, respectively (P < 0.05). Interestingly, plant uptake of lead and cadmium was lowest from ANC as compared to AC or AANC (P < 0.05), irrespective of the vegetable type. Consequently, DIM, HRI, and THQ for these metals were substantially lower in the former as compared to the latter compost materials. Further, HI from ANC material was 50% lower over the unfertilized control indicating the absence of noncarcinogenic human health risks via vegetable intake. This all indicates that from viewpoint of sustainable waste recycling in agriculture, anaerobic composting is superior to the other composting methods.

Abstract
Elevated exposure to arsenic disproportionately affects populations relying on private well water in the United States (US). This includes many American Indian (AI) communities where naturally occurring arsenic is often above 10 µg/L, the current US Environmental Protection Agency safety standard. The Strong Heart Water Study is a randomized controlled trial aiming to reduce arsenic exposure to private well water users in AI communities in North Dakota and South Dakota. In preparation for this intervention, 371 households were included in a community water arsenic testing program to identify households with arsenic ≥10 µg/L by inductively coupled plasma mass spectrometry (ICP-MS). Arsenic ≥10 µg/L was found in 97/371 (26.1%) households; median water arsenic concentration was 6.3 µg/L, ranging from <1-198 µg/L. Silica was identified as a water quality parameter that could impact the efficacy of arsenic removal devices to be installed. A low-range field rapid arsenic testing kit evaluated in a small number of households was found to have low accuracy; therefore, not an option for the screening of affected households in this setting. In a pilot study of the effectiveness of a point-of-use adsorptive media water filtration device for arsenic removal, all devices installed removed arsenic below 1 µg/L at both installation and 9 months post-installation. This study identified a relatively high burden of arsenic in AI study communities as well as an effective water filtration device to reduce arsenic in these communities. The long-term efficacy of a community based arsenic mitigation program in reducing arsenic exposure and preventing arsenic related disease is being tested as part of the Strong Heart Water Study.

Abstract
Since the first report of lathyrism in 1926, the ICMR-National Institute of Nutrition (NIN) at Hyderabad, India, has made tremendous contributions in the field of food toxins/food safety for the benefit of the people. The present article highlights the Institute's work on various food toxins/foodborne diseases since its inception and discusses the important contributions made in the context of public health protection that formed the basis for several national policies on their prevention and control. The investigations on food toxins, in the initial decades, were limited to the description of lathyrism and its endemicity. Subsequently, the horizon was broadened to include the problem of mycotoxins and mycotoxicosis, which had received global attention and variety of other disease outbreaks investigations leading to total food safety transition in the forthcoming decades. Important contributions in epidemiological investigations, reproduction of the disease in experimental animals, surveillance and monitoring studies, development of methods for detection of food toxins and contaminants, evolving strategies for prevention and control and developing the concept of risk assessment and risk management for addressing food safety issues in the country are discussed.

Abstract
The National Institute of Nutrition (NIN) has reached a remarkable milestone of completing 100 years of exemplary service to the nation. The long journey that started in a humble one-room laboratory at Coonoor (now in Tamil Nadu) in 1918 to a colossus of the nutrition research in the country today is dotted with several interesting vignettes. The NIN has always been at the forefront of need-based, pragmatic research. Its large-scale community-based interventions have been of great practical value in the nation's fight against malnutrition. The evolution of nutrition as a modern science almost coincides with the growth of the Institute. Being the oldest in the fraternity of institutes under the Indian Council of Medical Research (ICMR), the NIN has grown from strength to strength due to the sheer relevance of its contributions in furthering nutrition science and promoting public health in the country. This article provides a historical overview of the evolution and contributions of ICMR-NIN in the areas of nutrition, food safety, public health and policy.

Abstract
Efforts to prevent foodborne illnesses in food facilities require sufficient knowledge on hygiene and safety standards from both food processors and customers. However, studies about knowledge, attitude, and practices of customers towards these issues are constrained. This study explored the knowledge, attitude, and practices (KAP) of customers regarding the practices of food facilities as well as potential associated factors. A cross-sectional survey was conducted in Hanoi from September to October 2015. Questions about knowledge, attitude, and practice towards food hygiene and safety were asked, alongside sociodemographic characteristics. Multivariate Tobit regression was used to identify the associated factors with the KAP. Among 1740 customers, the highest mean score of 98.4 (SD = 10.1) was found in knowledge about practices with raw and cooked food, following by knowledge about environmental practices when processing food (mean = 93.1, SD = 17.3), and knowledge about environmental requirements when processing food (mean = 33.3, SD = 33.3). Most of customers considered the processing and selling of hygienic meals without leaving any food overnight as the most important feature for food facilities (73.8%). About 63.2% of participants chose not to report food safety violation by facilities to authorities. The higher score of knowledge was found in groups of people who were not single, had college/university or higher education, and had specific criteria when choosing their places to eat. These findings imply the need for enhancing customers’ protection systems, the capability of inspecting and supervising the food processing progress by local authorities, and the awareness of customers about the environmental requirements of food facilities.

Abstract
Flushing tap water is promoted as a low cost approach to reducing water lead exposures. This study evaluated lead reduction when prevailing flush guidelines (30 s–2 min) are implemented in a city compliant with lead-associated water regulations (New Orleans, LA, USA). Water samples (n = 1497) collected from a convenience sample of 376 residential sites (2015–2017) were analyzed for lead. Samples were collected at (1) first draw (n = 375) and after incremental flushes of (2) 30–45 s (n = 375); (3) 2.5–3 min (n = 373), and (4) 5.5–6 min (n = 218). There was a small but significant increase in water lead after the 30 s flush (vs. first draw lead). There was no significant lead reduction until the 6 min flush (p < 0.05); but of these samples, 52% still had detectable lead (≥1 ppb). Older homes (pre-1950) and low occupancy sites had significantly higher water lead (p < 0.05). Each sample type had health-based standard exceedances in over 50% of sites sampled (max: 58 ppb). While flushing may be an effective short-term approach to remediate high lead, prevailing flush recommendations are an inconsistently effective exposure prevention measure that may inadvertently increase exposures. Public health messages should be modified to ensure appropriate application of flushing, while acknowledging its short-comings and practical limitations.

Abstract
Fish consumption is a major pathway for mercury exposure in humans. Current guidelines and risk assessments assume that 100% of methylmercury (MeHg) in fish is absorbed by the human body after ingestion. However, a growing body of literature suggests that this absorption rate may be overestimated. We used an in vitro digestion method to measure MeHg bioaccessibility in commercially-purchased fish, and investigated the effects of dietary practices on MeHg bioaccessibility. Cooking had the greatest effect, decreasing bioaccessibility on average to 12.5±5.6%. Polyphenol-rich beverages also significantly reduced bioaccessibility to 22.7±3.8% and 28.6±13.9%, for green and black tea respectively. We confirmed the suspected role of polyphenols in tea as being a driver of MeHg's reduced bioaccessibility, and found that epicatechin, epigallocatechin gallate, rutin and cafeic acid could individually decrease MeHg bioaccessibility by up to 55%. When both cooking and polyphenol-rich beverage treatments were combined, only 1% of MeHg remained bioaccessible. These results call for in vivo validation, and suggest that dietary practices should be considered when setting consumer guidelines for MeHg. More realistic risk assessments could promote consumption of fish as a source of fatty acids, which can play a protective role against cardiovascular disease.

Abstract
Domoic Acid (DA) is a marine-based neurotoxin. Dietary exposure to high levels of DA via shellfish consumption has been associated with Amnesic Shellfish Poisoning, with milder memory decrements found in Native Americans (NAs) with repetitive, lower level exposures. Despite its importance for protective action, the clinical relevance of these milder memory problems remains unknown. The purpose of this study was to determine whether repeated, lower-level exposures to DA impact everyday memory (EM), i.e., the frequency of memory failures in everyday life. A cross-sectional sample of 60 NA men and women from the Pacific NW was studied with measures of dietary exposure to DA via razor clam (RC) consumption and EM. Findings indicated an association between problems with EM and elevated consumption of RCs with low levels of DA throughout the previous week and past year after controlling for age, sex, and education. NAs who eat a lot of RCs with presumably safe levels of DA are at risk for clinically significant memory problems. Public health outreach to minimize repetitive exposures are now in place and were facilitated by the use of community-based participatory research methods, with active involvement of state regulatory agencies, tribe leaders, and local physicians.

Abstract
The wide occurrence of Cd-contaminated rice in southern China poses significant public health risk and deserves immediate action, which arises primarily from extensive metal (including Cd) contamination of paddies with the fast expansion of nonferrous metal mining and smelting activities. Accumulation of Cd in rice grains can be reduced by removing Cd from the contaminated paddy soils, reducing its bioavailability, and controlling its uptake by rice plants. Although a range of measures can be taken to rehabilitate Cd-contaminated lands, including soil replacement and turnover, chemical washing, and phytoremediation, they are either too expensive and/or too slow. Various amendment materials, including lime, animal manures, and biochar, can be used to immobilize Cd in soils, but such fixation approach can only temporarily reduce Cd availability to rice uptake. Cultivation of alternative crops with low Cd accumulation in edible plant parts is impractical on large scales due to extensive contamination and food security concerns in southern China. Transgenic techniques can help develop rice cultivars with low Cd accumulation in grains, but little public acceptance is expected for such products. As an alternative, selection and development of low-Cd rice varieties and hybrids through plant biotechnology and breeding, particularly, by integration of marker-assisted selection (MAS) with traditional breeding, could be a practical and acceptable option that would allow continued rice production in soils with high bioavailability of Cd. Plant biotechnology and breeding can also help develop Cd-hyperaccumulating rice varieties, which can greatly facilitate phytoremediation of contaminated paddies. To eliminate the long-term risk of Cd entering the food chain, soils contaminated by Cd should be cleaned up when cost-effective remediation measures are available.

Abstract
There was investigated the impact of chemical substances contained in the public health foodstuffs in eight regions of the Republic of Tatarstan on 11 product groups: meat and meat products, fish and fish products, milk and dairy products, bread and bakery products, sugar and confectionery products, vegetables and melons (excluding potatoes), potatoes, fruits and berries, vegetable oil, eggs and egg products, salt. In total there were analyzed more than 240 thousand samples offood raw materials andfood products over the period offrom 2006 to 2014. The study took place on 27 priority chemicals, including thirteen carcinogens (benzo (a) pyrene, DDT, hexachlorobenzene, hexachloran, heptachlor, alpha-lindane, beta-lindane, lindane, cadmium, arsenic, lead, derivatives of 2,4-D acid, cypermethrin). Exposition load is calculated by the 50 (median), and 90 percentiles of the content ofpollutants in food products. There were calculated carcinogenic risks, HQ coefficients and HI indices for chronic non-cancer exposure. High values of the total cancer risk (3.31*10 at the median level of 1.49*10+ at the 90 percentile) are associated with the exposure to tohexachlorane and alpha-lindane seem to be alarming (from 1.73*10 to 9.68*10) with the effect of lindane, cadmium and lead with dominant contribution to the total risk in the use of meat and meat products, milk and dairy products. The warning value of Hazard ratios (HQ 1.1-3) at 90-percentile were shown on nitrate, lead, beta-lindane, high (HQ >3), for DDT and its metabolites, lindane and arsenic, with the dominant contribution to the exposure of vegetables and melons (excluding potatoes), potato, milk and milk products.
