Abstract
Salmonella is one of the most common foodborne pathogens. A total of 70–80% of bacterial food poisoning is caused by Salmonella in China. From 2015 to 2023, a total of 1945 samples in 6 food categories were collected in Huzhou for monitoring of Salmonella. Epidemiological analysis, serotyping, and antibiotic sensitivity testing were conducted on isolated Salmonella. Ninety Salmonella strains were detected from 1945 samples, and the total detection rate was 4.63%. Among all kinds of food, the detection rate of Salmonella in raw animal meat (8.93%) and raw poultry meat (8.54%) was the highest. Salmonella had also been detected in ready-to-eat foods (bulk cooked meat, Chinese cold dishes) and emerging food categories (seasoned raw meat and premade dishes). A total of 24 serotypes of Salmonella were detected, of which the dominant serotype was Salmonella Typhimurium. The serotypes of Salmonella detected in different types of food were different. The results showed that the isolates had strong resistance to ampicillin (AMP) and tetracycline (TET).
