Purpose: Consumption of raw beef infected with multidrug-resistant Salmonella is pertinent to the world public health risk of antimicrobial resistance. Henceforth, this study aimed to investigate the carriage, antimicrobial resistance (AR) patterns, and the revealing risk factors of Salmonella-contaminating beef in abattoirs and butcher shops in Jimma town.
Methods: A cross-sectional study was conducted to investigate the carriage and AR patterns and to reveal the risk factors of beef contaminated by Salmonella spp. Three hundred and forty-eight swab samples were collected from abattoirs (n=210) and butcher shops (n=138) and the conventional cultural methods were employed for identification of Salmonella. Isolates were subjected to 12 antimicrobials using the Kirby-Bauer disk diffusion method for AR patterns.
Results: The occurrence of Salmonella isolates from the abattoir samples was 11.4%, whereas about 6.52% of isolates were recovered from butcher shops. Educational status (abattoir: odds ratio (OR)=8.40, confidence interval (CI)=1.186-59.493; butcher shops: OR=9.17, CI=1.15-73.239), job related training (abattoir: OR=5.50, CI=1.065-28.416), contamination risk perception (abattoir: OR=5.31, CI=1.256-22.489), neatness of knives (abattoir: OR=7.6, CI=0.892-65.376), source of contamination (abattoir: OR=8.44, CI=1.682-42.39), wearing of protective cloth (butcher shops: OR=8.44, CI=1.682-42.39), manner of hand washing (butcher shops: OR=7.25, CI=1.210-43.442), and money handling (butcher shops: OR= 9.69, CI=1.578-59.474) were among the potential risk factors significantly associated with Salmonella carcass contamination in the abattoir and butcher shops. Of the 33 Salmonella isolates, 14 (58.3%) and six (66.7%) of the abattoir and butcher shops isolates, correspondingly, were resistant to two or more antibiotics.
Conclusion: The finding of this investigation exhibited extensive multidrug-resistant Salmonella isolates in the study setting. Hence, establishing standard meat safety requirements and provision of training for meat handlers and prudent use of antimicrobials are recommended.

Background: Meat is a good source of protein in the human diet, and more than three-quarters of the world's population consumes it. It is the most perishable food item since it has enough nutrients to enable microbial growth. In underdeveloped nations, animals are routinely slaughtered and sold in unsanitary conditions, compromising the bacteriological quality and safety of the meat received from the animals.

Background And Aim: subspecies paratuberculosis (MAP) causes Johne's disease (paratuberculosis), which is a chronic wasting disease. No previous study has been found to investigate the coinfection of gastrointestinal parasites with paratuberculosis. This study aimed to investigate the relationship between paratuberculosis and gastrointestinal parasitism in naturally infected local Awassi (AS) and imported Tsurcana (TS) sheep.

non-typhoidal is a major contributor to diarrheal diseases, with over 2600 serovars identified across diverse environments. In Mexico, serovars Newport and Anatum have shown a marked increase, especially in foodborne disease, posing a public health problem. We conducted a cross-sectional study from 2021 to 2023 using active epidemiological surveillance to assess contamination in ground beef and pork at butcher shops nationwide.

Article Synopsis
- The study examines the presence of tigecycline resistant Enterobacterales (TRE) in the gut of healthy birds and in meat samples, revealing a significant prevalence in poultry.
- Out of 960 samples, 19.21% from chicken farms and 13.3% from turkey farms tested positive for TRE, with specific strains of E. coli identified carrying the tet(X4) gene, indicating multi-drug resistance.
- Findings suggest that food-producing animals could be a source of TRE for humans, highlighting the need for active surveillance to mitigate public health risks related to these resistant bacteria.

Article Synopsis
- The study investigated the prevalence of nontyphoidal Salmonella in animal products (beef, chicken, and dairy) from Bejaia, Algeria, finding a 3.5% contamination rate among 1450 samples, with traditional sausages showing the highest occurrence at 14.1%.
- Fifteen serotypes were identified, with Kentucky, Anatum, and Bredeney being the most common, while antimicrobial susceptibility testing revealed notable resistance to antibiotics such as tetracycline and ampicillin.
- Whole-genome sequencing revealed phylogenetic connections between different isolates, indicating early-stage contamination in the food supply chain, along with the presence of antibiotic resistance genes linked to
