Mucosal IFNγ production and potential role in protection in Escherichia coli O157:H7 vaccinated and challenged cattle.

Sci Rep 2021 May 7;11(1):9769. Epub 2021 May 7.

USDA-ARS, National Animal Disease Center, 1920 Dayton Avenue, P.O. Box 70, Ames, IA, 50010, USA.

Shiga-toxin producing Escherichia coli O157:H7 (O157)-based vaccines can provide a potential intervention strategy to limit foodborne zoonotic transmission of O157. While the peripheral antibody response to O157 vaccination has been characterized, O157-specific cellular immunity at the rectoanal junction (RAJ), a preferred site for O157 colonization, remains poorly described. Vaccine induced mucosal O157-specific antibodies likely provide some protection, cellular immune responses at the RAJ may also play a role in protection. Read More

Appl Environ Microbiol 2021 May 7. Epub 2021 May 7.

Department of Biology, Faculty of Medicine, Masaryk University, Kamenice 5, 625 00 Brno, Czech Republic

Enterotoxigenic (ETEC) and Shiga toxin-producing (STEC) strains are the causative agents of severe foodborne diseases in both humans and animals. In this study, porcine pathogenic strains (n = 277) as well as porcine commensal strains (n = 188) were tested for their susceptibility to 34 bacteriocin monoproducers to identify the most suitable bacteriocin types inhibiting porcine pathogens. Under condition, the set of pathogenic was found to be significantly more susceptible to a majority of tested bacteriocins when compared to commensal Based on production of bacteriocins with specific activity against pathogen, three potentially probiotic commensal strains of human origin were selected.

Comparative macrolide use in humans and animals: should macrolides be moved off the World Health Organisation's critically important antimicrobial list?

J Antimicrob Chemother 2021 May 6. Epub 2021 May 6.

Veterinary Medicine Research and Development, Zoetis, Inc, Kalamazoo, MI, USA.

Macrolide antibiotics are categorized by the WHO as Highest Priority, Critically Important Antimicrobials due to their recommendation as treatment for severe cases of campylobacteriosis in humans; a self-limiting, rarely life-threatening, zoonotic foodborne infection. Low rates of macrolide resistance in Campylobacter jejuni and the availability of alternative treatments have prompted some regulatory schemes to assign macrolides to a lower importance category. Apart from rare, specific infections, macrolides largely play a supportive role to other drug classes in human medicine. Read More

Integrating the Food and Drug Administration Office of the Coordinated Outbreak Response and Evaluation Network's foodborne illness outbreak surveillance and response activities with principles of the National Incident Management System.

J Emerg Manag 2021 Mar-Apr;19(2):131-141

Food and Drug Administration, Center for Food Safety and Applied Nutrition, Office of the Coordinated Outbreak Response and Evaluation Network, College Park, Maryland.

The Food Safety Modernization Act mandates building a national Integrated Food Safety System, which represents a seamless partnership among federal, state, local, territorial, and tribal agencies. During multistate foodborne illness outbreak investigations, local and state partners, the Centers for Disease Control and Prevention, the United States Food and Drug Administration (FDA), or the United States Department of Agriculture Food Safety Inspection Service, depending on the regulated food product, become engaged and assist in coordinating the efforts between partners involved and determine the allocation of resources. The FDA Center for Food Safety and Applied Nutrition (CFSAN) Office of the Coordinated Outbreak Response and Evaluation (CORE) Network coordinates foodborne illness outbreak surveillance, response, and post-response activities related to incidents involving multiple illnesses linked to FDA-regulated human food, dietary supplements, and cosmetic products.

Plants (Basel) 2021 Apr 29;10(5). Epub 2021 Apr 29.

Faculty of Engineering, Autonomous University of Guerrero, Chilpancingo, Guerrero 39087, Mexico.

Improper usage of nitrogen in cucumber cultivation causes nitrate accumulation in the fruit and results in food poisoning in humans; therefore, mandatory evaluation of food products becomes inevitable. Hyperspectral imaging has a very good ability to evaluate the quality of fruits and vegetables in a non-destructive manner. The goal of the present paper was to identify excess nitrogen in cucumber plants. Read More

Direct identification and molecular characterization of zoonotic hazards in raw milk by metagenomics using as a model pathogen.

Microb Genom 2021 May;7(5)

Department of Biological Safety, German Federal Institute for Risk Assessment, Berlin, Germany.

Metagenomics is a valuable diagnostic tool for enhancing microbial food safety because (i) it enables the untargeted detection of pathogens, (ii) it is fast since primary isolation of micro-organisms is not required, and (iii) it has high discriminatory power allowing for a detailed molecular characterization of pathogens. For shotgun metagenomics, total nucleic acids (NAs) are isolated from complex samples such as foodstuff. Along with microbial NAs, high amounts of matrix NAs are extracted that might outcompete microbial NAs during next-generation sequencing and compromise sensitivity for the detection of low abundance micro-organisms.
