“…Salmonellosis has several clinical signs, such as gastroenteritis, nausea, vomiting, abdominal pain and lead to bacteremia. The bacteria are readily transmitted among humans, animals and environments (Matias et al, 2010;Castro Rosas, 2012;Hur et al, 2012). Infected individuals may carry bacteria asymptomatically.…”

Foodborne disease associated with Salmonella spp. occurs in some parts of the world, including Thailand. The present study aimed to determine prevalence, antimicrobial resistance, and serotypes of Salmonella spp. isolated from chicken meat in upper northeastern Thailand. A total of 326 swab samples of fresh chicken meat were collected from wet markets in Khon Kaen, U-don Thani, Nong Khai, Loei, Kalasin, Maha Sarakham, and Bueng Kan Provinces, northeastern Thailand, between August and November 2019. All samples were analyzed for Salmonella spp. using the ISO 6579:2002/AMD 1:2007 method. The isolates were tested for antimicrobial susceptibility using the Kirby-Bauer method, and the serotypes of isolates positive were identified. The overall prevalence of Salmonella spp. isolated from chicken meat was 36.2% (118/326), and prevalence in the provinces was as follows: U-don Thani, 70.9%; Bueng Kan, 66.67%; Khon Kaen, 45.9%; Kalasin, 31.25%; Nong Khai, 29.8%; Maha Sarakham, 26.42% and Loei, 12.5%. Resistance was highest for nalidixic acid at 31%, followed by ampicillin (24%), tetracycline (19%), sulfamethoxazole trimethoprim (8%), norfloxacin (5%), ciprofloxacin (4%), amoxicillin (4%), and chloramphenicol (1%). However, all isolates were susceptible to ceftazidime. Twenty-seven serotypes were detected, with the Corvallis, Singapore, Kentucky and Agona serotypes being the most common. Salmonella spp. were detected in a large percentage of the swab samples of chicken meat in every city, indicating a high level of contamination of chicken meat. Given the high resistance of Salmonella strains to some antibiotics, it may be beneficial to find other drugs for salmonellosis treatment and to use antibiotics more wisely.

“…are among of the most important foodborne pathogens, causing about 155 000 salmonellosis-related deaths each year worldwide (Majowicz et al, 2010). Salmonellosis is a zoonotic infection transmitted to humans through the fecal-oral route, the primary source of transmission being infected eggs and egg-derived products, meat, poultry, milk and milk-derived products, fruits and vegetables (Gómez-Aldapa et al, 2012). Salmonella enterica serovar Typhimurium (S. Typhimurium) and S. Enteritidis are currently the most usual serotypes related to salmonellosis outbreaks (20.2 and 39.5% of the reported cases, respectively) (EFSA, 2015).…”

The aims of this research study were: (i) to postulate Caenorhabditis elegans (C. elegans) as a useful organism to describe infection by Salmonella enterica serovar Typhimurium (S. Typhimurium), and (ii) to evaluate changes in virulence of S. Typhimurium when subjected repetitively to different antimicrobial treatments. Specifically, cauliflower by-product infusion, High Hydrostatic Pressure (HHP), and Pulsed Electric Fields (PEF). This study was carried out by feeding C. elegans with different microbial populations: E. coli OP50 (optimal conditions), untreated S. Typhimurium, S. Typhimurium treated once and three times with cauliflower by-product infusion, S. Typhimurium treated once and four times with HHP and S. Typhimurium treated once and four times with PEF. Bayesian survival analysis was applied to estimate C. elegans lifespan when fed with the different microbial populations considered. Results showed that C. elegans is a useful organism to describe infection by S. Typhimurium because its lifespan was reduced when it was infected. In addition, the application of antimicrobial treatments repetitively generated different responses: when cauliflower by-product infusion and PEF treatment were applied repetitively the virulence of S. Typhimurium was lower than when the treatment was applied once. In contrast, when HHP treatment was applied repetitively, the virulence of S. Typhimurium was higher than when it was applied once. Nevertheless, in all the populations analyzed treated S. Typhimurium had lower virulence than untreated S. Typhimurium.

Organic and conventional animal products may include residues of veterinary drugs and environmental contaminant. Food contaminants can cause consumer illness such as allergy, immunosuppression, cancer, teratogenicity, mutagenicity and genotoxicity. Therefore, their control is an important issue in terms of public health. In this article, information is given about contaminants such as bacterial, fungal, metal pesticides and veterinary drug that can be found in organic and conventional animal products. In addition, the effects of various cooking and freezing processes on contaminants in animal foods and their legal regulation have been mentioned.
