This study investigated Salmonella contamination in food of animal origin in different cities of Khuzestan province, Iran. This study was conducted for 6 months a year in slaughterhouses in various cities in Khuzestan province. Sixty-five samples, including red meat, chicken, and shrimp, were sampled and tested. A total bacterial count, identification, and confirmation of Salmonella infection were performed using microbial tests and general and specific culture media. The highest average bacterial load was related to chicken wings in Behbahan city and was higher than the standard. Also, the highest rate of Salmonella infection in fresh chicken in Khorramshahr city and beef (frozen) in Ramshir city was higher than the standard. No Salmonella infection was observed in farmed, frozen, and peeled shrimp in Khorramshahr, Abadan, and Dezful. The high prevalence is often due to poor hygiene measures during transportation from food preparation and distribution centers to the animal feed market and is associated with Salmonella contamination. To reduce the burden of microbial contamination, periodic microbial tests and implementation of monitoring and control plans for critical points from slaughterhouses to supply and distribution centers, especially in cities with higher pollution levels, and improving the level of hygiene in slaughterhouses and food preparation and distribution centers of animal origin

Different species of Salmonella are important pathogenic bacteria in animals and humans that often infect poultry flocks. Most Salmonella infections in humans are caused by eating foods contaminated with this bacterium. The aim of this study was to determine the Salmonella infection status of several poultry farms in Khuzestan province and to determine the serotypes and antimicrobial resistance pattern of isolated Salmonella. In the year 1392 total of 1829 samples including stool swabs, litter samples, feathers and eggshells were collected from a broiler mother farm, two laying mother hen farms and an incubator and cultured in enriching and selective media and detected using biochemical tests according to standard methods. In this study, 10 Salmonella isolates were isolated including serotypes enteritidis (3 cases), corvallis (3 cases), typhimurium (3 cases) and ruzizi (1 case) using Salmonella serum type tests. After performing antibiogram test with standard disk diffusion method, it was determined that 100% of the isolates were resistant to Colistin, Cefalexin and Cefazolin. Isolates were highly resistant to Ceftazidime, Nalidixic acid, Ampicillin, Ciprofloxacin, Nitrofurantoin, Amoxicillin, Neomycin, Streptomycin, Kanamycin, Ceftizoxime, Gentamicin and Tetracycline. All Salmonella isolates in this study were sensitive to Amikacin, Enrofloxacin, Ceftriaxone, Imipenem, Cefixime, Cefotaxime, Ofloxacin, Cefepime, Piperacillin, Florfenicol, Furazolidone, Chloramphenicol and Trimethoprim- Sulfamethoxazole.

Today , salmonella is one of the most important causes of food disease in the world. The purpose of this study was to evaluate the effect washing stages of carcasses and chiller in contamination rate of carcasses to Salmonella in industrial Slaughterhouses. In this study five carcasses were randomly sampled for each stage of the six stages of slaughter of poultry so from every slaughterhouse 30 carcass samples and total 180 samples were taken of 6 slaughterhouses which are active in the Khuzestan Province. After rinsing carcasses with peptone water medium of each carcass was prepared 100 ml sample (carcass rinses solation) which were sent to the laboratory for microbiological tests.In the research was determined Salmonella contamination In 65% (117 samples), tested carcasses were positive and in 35% (63 samples) negative. Salmonella contamination was determined in samples after Scalding 56.6%, after plucking 66.6%, before evisceration 60%, after evisceration 70%, before the chiller 63.3% and after the chiller 73.3%.The results showed significant effect washing carcasses in reduce contamination to Salmonella and the significant effect of the chiller (immersion) stage on increasing the carcass contamination with Salmonella.
