Abstract Biofilm formation by foodborne pathogens is a serious threat to food safety and public health. Meat processing plants may harbor various microorganisms and occasional foodborne pathogens; thus, the environmental microbial community might impact pathogen survival via mixed biofilm formation. We collected floor drain samples from two beef plants with different E. coli O157:H7 prevalence history and investigated the effects of the environmental microorganisms on pathogen sanitizer tolerance. The results showed that biofilm forming ability and bacterial species composition varied considerably based on the plants and drain locations. E. coli O157:H7 cells obtained significantly higher sanitizer tolerance in mixed biofilms by samples from the plant with recurrent E. coli O157:H7 prevalence than those mixed with samples from the other plant. The mixed biofilm that best protected E. coli O157:H7 also had the highest species diversity. The percentages of the species were altered significantly after sanitization, suggesting that the community composition affects the role and tolerance level of each individual species. Therefore, the unique environmental microbial community, their ability to form biofilms on contact surfaces and the interspecies interactions all play roles in E. coli O157:H7 persistence by either enhancing or reducing pathogen survival within the biofilm community.

This study was carried out to assess the quality of some RTE (ready to eat) chicken meat products collected from different poultry meat processing plants in Menofia and Gharbia governorate. a A total of 60 commercially produced RTE poultry products such as chicken ham, chicken shawarma, chicken with herps, smoked turkey and turkey smoked lobes (12 each) were collected from supermarkets and examined for sensory, deterioration criteria and bacteriological quality. The results revealed that the sensory panel scores of all examined RTE poultry meat products samples were generally low especially in chicken with herps, chicken ham and smoked turkey RTE poultry meat products. Moreover, pH values of most of the examined samples were relatively alkaline whereas the lowest value was recorded in smoked turkey samples and highest value was observed in chicken with herps samples. In addition, higher thiobarbituric acid (smoked turkey) and slightly increases of total volatile basic nitrogen values (chicken with herps) were recorded in most of the examined samples. All investigated bacterial counts were significantly high in all examined RTE poultry meat products samples. Staph. aureus was isolated from chicken ham and E. coli strains were isolated from chicken shawarma, smoked turkey and turkey smoked lobes. However, E. coli O157:H7 and salmonella strains failed to be isolated from all the examined samples. It could be concluded that all the examined RTE poultry meat products were deteriorated in terms of sensory, chemical and bacteriological terms and exceeded the limit described by E.S. (3493/2005) for cooked poultry meat products. In addition, these samples were probably produced and prepared under bad hygienic measures which could be responsible for lowering their quality and reduce shelf life.

The growth in the use of antibiotic and chemical substances in meat processing plants shows the need to search for alternative means of decontamination, the most promising of which are bacteriophages. However, there are a lot of little-studied questions on their use, one of which is the effect of bacteriophages on viable but nonculturable (VBNC) cells of bacteria. In this regard, the article provides data on the analysis of the activity of commercial bacteriophages in relation to bacteriacontaminants of raw materials of animal origin, in particular E. coli and Salmonella enterica typhimurium, as well as their VBNC-cells.

Cattle are asymptomatic carriers of Shiga toxin-producing E. coli (STEC) that can cause serious illness or death in humans. In New Zealand, contact with cattle feces and living near cattle populations are known risk factors for human STEC infection. Contamination of fresh meat with STECs also has the potential for rejection of consignments by importing countries. We used a combination of PCR/MALDI-TOF and whole genome sequencing to evaluate the presence and transmission of STEC on farms and in processing plants to better understand the potential pathways for human exposure and thus mitigate risk. Animal and environmental samples (n=2,580) were collected from six farms and three meat processing plants in New Zealand during multiple sampling sessions in spring of 2015 and 2016. PCR/MALDI-TOF analysis revealed 6.2% were positive for ‘Top 7’ STEC. ‘Top 7’ STEC were identified in all sample sources (n=17) tested. A marked increase in ‘Top 7’ STEC prevalence was observed between calf hides on-farm (6.3% prevalence), and calf hides at processing plants (25.1% prevalence). Whole genome sequencing was performed on ‘Top 7’ STEC bacterial isolates (n=40). Analysis of STEC O26 (n=25 isolates) revealed relatively low genetic diversity on individual farms, consistent with the presence of a resident strain disseminated within the farm environment. Public health efforts should focus on minimizing human contact with fecal material on farms and during handling, transport and slaughter of calves. Meat processing plants should focus on minimizing cross-contamination between the hides of calves in a cohort during transport, lairage and slaughter. Importance Cattle are asymptomatic carriers of Shiga toxin-producing E. coli (STEC), which can cause serious illness or death in humans. Contact with cattle feces and living near cattle are known risk factors for human STEC infection. This study evaluated STEC carriage in young calves and the farm environment with an in-depth evaluation of six farms and three meat processing plants over two years. An advanced molecular detection method and whole genome sequencing were used to provide a detailed evaluation of the transmission of STEC both within and between farms. The study revealed widespread STEC contamination within the farm environment, but no evidence of recent spread between farms. Contamination of young dairy calf hides increased following transport and holding at meat processing plants. The elimination of STEC in farm environments may be very difficult given the multiple transmission routes; interventions should be targeted at decreasing fecal contamination of calf hides during transport, lairage, and processing.

Foodborne pathogens represent one of the major challenges to health systems around the world. This risk is exacerbated by the presence of antimicrobial resistant (AMR) pathogens. Knowledge of the presence of these pathogens in the food supply chain would help in establishing intervention strategies to mitigate their risk. The objective of this study was to detect AMR among serotypes of Escherichia coli (E. coli) food adulterants serotypes of E. coli in the food supply chain and among isolates from gastroenteritis cases. E. coli isolates recovered from animals, meat processing plants, retail, and humans were examined for the presence of AMR using phenotypic and genotypic approaches. AMR to aminoglycosides, β-lactams, and tetracycline were detected in all isolates recovered from these sources at different levels. Similarly, presence of the bla-Tem, bla-SHV, aadA, and strAB genes were detected in isolates from these sources but there was no significant correlation between the genetic detection and phenotypic expression AMR.

SUMMARYSamples of ground beef (225), pork (235) and chicken (200) were randomly selected from meat processing plants in the southwestern Ontario area. Supernatants of broth cultures of the samples were tested for verocytotoxins using a Vero cell assay. Neutralization of cytotoxic activity using antisera specific for three types of verocytotoxin (Verotoxin 1, Verotoxin 2 and Shiga-like toxin II) was performed on positive samples. Isolation of verocytotoxigenicEscherichia coli(VTEC) was attempted from positive samples. VTEC were confirmed asE. colibiochemically, tested for drug resistance, and serotyped. Based on neutralization studies, the prevalance of VTEC in beef and pork was at least 36·4% and 10·6%. respectively. This is much higher than has been reported from a survey of retail meats in which a method designed to detect onlyE. coliO 157.H7 was used. Isolations of VTEC were made from 10·4 % of the beef samples and 3·8 % of the pork samples. No VTEC were recovered from the chicken samples. The majority of VTEC isolates were susceptible to commonly used antimicrobial agents. A number of the serotypes of the VTEC isolates recovered have been associated with human disease; however, no VTEC of serotype O 157.H7 were isolated.
