Abstract
Food safety encompasses the supply and assurance of safe, high-quality food for consumers. It is a crucial aspect of food security, gaining greater global attention due to the increasing number of widespread foodborne incidents. International trade is expanding as countries increasingly rely on each other to secure a sufficient and diverse food supply. Beyond this, concerns about food safety have become more prevalent due to various factors. Therefore, this review aims to investigate the effects of food safety-associated risks on the international trade of food and related products. A total of 37 published studies retrieved using different search engines were included in this review. This review revealed that because of rapid population growth and rising food demand in developing nations, agricultural intensification is growing. It has been found that foodborne illnesses and associated discrepancies can impede the international trade of food commodities. Trade bans due to the fear of foodborne illnesses are growing. The consequences of foodborne diseases are multifaceted and include financial losses from trade restrictions, medical costs for prevention or control, resource depletion and a decline in food production. The overall effects are increased international trade tensions and livelihood vulnerability to poverty, notably for small-scale livestock producers. Potential food contaminants include microbes, pesticides, pharmaceutical residues, heavy metals and fraudulent such as improper food processing, mislabelling, poor packaging, adulteration and substitution. Hence, countries are encouraged to harmonize the rights and duties set by the World Trade Organization under sanitary and phytosanitarys to maximize their advantages in global markets. Based on this evidence, we recommend that each country develop and integrate regulations that would ensure the safety of both domestic and international food production systems. Furthermore, the global community should either revise the current functioning food regulatory and monitoring body or establish a more genuine collaborative network.

Ghali-Mohammed I, Odetokun IA, Raufu IA, Adetunji VO. Whole genome sequencing analysis of non-O157 Shiga toxin-producing Escherichia coli in milk in Kwara State, Nigeria. IRANIAN JOURNAL OF VETERINARY RESEARCH 2024; 25:92-97. [PMID: 39624192 PMCID: PMC11608529 DOI: 10.22099/ijvr.2024.49643.7307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 06/24/2024] [Indexed: 01/05/2025]
Abstract
BACKGROUND Escherichia coli is a major cause of poor microbial quality of milk, often resulting from unhygienic milk handling. Milk contamination poses public health concerns. Shiga toxin-producing Escherichia coli (STEC) strains in food products, particularly milk, is a critical concern for public health. Limited information exists on the detection of non-O157 E. coli pathotypes in milk sold by local processors in Nigeria. AIMS This study aimed to explore the diversity of non-O157 STEC isolates found in commercially available milk in Kwara State, Nigeria, to find the genetic diversity and potential risks associated with these strains. METHODS A subgroup of 18 representative non-O157 STEC isolated from milk samples (n=1225) was selected for whole genome sequencing (WGS) analysis. RESULTS Four novel sequence types (ST): ST398, ST540, ST1727, and ST9891 of non-O157 E. coli involving five serotypes: O176:H30, O176:H20, O8:H20, O21:H45, and O22:H7, carrying variable proportions of virulence factors, antimicrobial resistance genes, and plasmids, were identified. CONCLUSION This investigation contributes valuable data to the ongoing efforts to ensure food safety and prevent the transmission of E. coli strains through dairy products. The findings have implications for public health policies and food quality standards in Kwara State, Nigeria. Improved hygienic practices during milk handling are recommended.

Multi-Drug Resistant Staphylococcus aureus Carriage in Abattoir Workers in Busia, Kenya. Antibiotics (Basel) 2022; 11:1726. [PMID: 36551383 PMCID: PMC9774130 DOI: 10.3390/antibiotics11121726] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 11/28/2022] [Accepted: 11/29/2022] [Indexed: 12/03/2022] Open
Abstract
Abattoir workers have been identified as high-risk for livestock-associated Staphylococcus aureus carriage. This study investigated S. aureus carriage in abattoir workers in Western Kenya. Nasal swabs were collected once from participants between February-November 2012. S. aureus was isolated using bacterial culture and antibiotic susceptibility testing performed using the VITEK 2 instrument and disc diffusion methods. Isolates underwent whole genome sequencing and Multi Locus Sequence Types were derived from these data. S. aureus (n = 126) was isolated from 118/737 (16.0%) participants. Carriage was higher in HIV-positive (24/89, 27.0%) than HIV−negative participants (94/648, 14.5%; p = 0.003). There were 23 sequence types (STs) identified, and half of the isolates were ST152 (34.1%) or ST8 (15.1%). Many isolates carried the Panton-Valentine leucocidin toxin gene (42.9%). Only three isolates were methicillin resistant S. aureus (MRSA) (3/126, 2.4%) and the prevalence of MRSA carriage was 0.4% (3/737). All MRSA were ST88. Isolates from HIV-positive participants (37.0%) were more frequently resistant to sulfamethoxazole/trimethoprim compared to isolates from HIV-negative participants (6.1%; p < 0.001). Similarly, trimethoprim resistance genes were more frequently detected in isolates from HIV-positive (81.5%) compared to HIV-negative participants (60.6%; p = 0.044). S. aureus in abattoir workers were representative of major sequence types in Africa, with a high proportion being toxigenic isolates. HIV-positive individuals were more frequently colonized by antimicrobial resistant S. aureus which may be explained by prophylactic antimicrobial use.
