The transmission of Salmonella spp. to human through the consumption contaminated food products animal origin, mainly poultry is a significant global public health concern. emerging multidrug resistant (MDR) clones non-typhoidal (NTS) serovars, have spread rapidly worldwide both in humans and chain. In this study NTS strains were isolated from diseased laying hens Iran further studied by whole-genome sequencing (WGS) investigate prevalent multilocus sequence types, antimicrobial resistance virulence genes. Out eight six identified as S. Enteritidis serovar ST11 (n = 5) or ST5824 1), two isolates recognized Kentucky serotype ST198 lineages. aminoglycoside gene aac(6′)-Iaa was most frequently detected being present all but it did not confer phenotypic corresponding agents (tobramycin amikacin). All carried single GyrA D87N/Y substitution. Other genes (ARGs) including tetA, floR, sul1, dfrA1, aph(3′)-Ia double gyrA parC mutations conferring high-level ciprofloxacin (CIPR) (MIC ≥ 16mg/L) only found isolates. comparison genotypic (AMR) profiles revealed inconsistent results for some antibiotics. A total 11 different Pathogenicity Islands (SPIs) SPIs-1, 5, 9, 10, 13, 14, C63PI, CS54 several related type III secretion system, adhesins, iron magnesium uptake, serum peptide among Our reports emergence highly MDR- CIPR clone form associated sources Iran. presence numerous determinants, SPIs ARGs examined poses risk safety. inconsistencies between AMR indicate that WGS data alone may be always sufficient guiding therapeutic strategies.

Impact of Metabolites from Foodborne Pathogens on Cancer

Foods, Journal Year: 2024, Volume and Issue: 13(23), P. 3886 - 3886

Published: Dec. 1, 2024

Foodborne pathogens are microorganisms that cause illness through contamination, presenting significant risks to public health and food safety. This review explores the metabolites produced by these pathogens, including toxins secondary metabolites, their implications for human health, particularly concerning cancer risk. We examine various such as Salmonella sp., Campylobacter Escherichia coli, Listeria monocytogenes, detailing specific of concern carcinogenic mechanisms. study discusses analytical techniques detecting chromatography, spectrometry, immunoassays, along with challenges associated detection. covers effective control strategies, processing techniques, sanitation practices, regulatory measures, emerging technologies in pathogen control. manuscript considers broader highlighting importance robust policies, awareness, education. identifies research gaps innovative approaches, recommending advancements detection methods, preventive policy improvements better manage foodborne metabolites.

Spatial analysis of milk and cottage cheese reveals poor microbial quality and contamination with foodborne pathogens in the central highlands of Ethiopia

Frontiers in Sustainable Food Systems, Journal Year: 2025, Volume and Issue: 8

Published: Jan. 20, 2025

Introduction Foodborne diseases that result from a wide range of illnesses caused by contaminated foods remain challenge in least-developed countries. The objective this study was to evaluate microbial quality and safety milk cottage cheese spatial distribution indicators foodborne pathogens along the dairy value chain three regions country. Methods A cross-sectional conducted December 2020 May 2021. total 912 samples were collected tested for aerobic plate count, coliform Escherichia coli Listeria monocytogenes , Salmonella enterica Campylobacter spp., according standard methods enumerations isolation procedures. Results Microbial found poor quality, as bacteria count estimated be 98% (95% CI 97.2–98.9%), 61.2% 58–64.3%), 28.6% 25.8–31.6%), respectively. load exceeded limits set Ethiopian Standards Agency. overall prevalence at least one pathogen 50.3% 47.1–53.7%), indicating raw collectors predominantly (OR = 2.1, p 0.003), followed processors 1.3, 0.003). Discussion analysis revealls standards concentrated central highlands Ethiopia, within nearly 100 kilometers radius Addis Ababa city surrounding towns. This offers some insight into importance food traceability prevent threats intervention areas.
