Abstract:
Objective To realize the epidemiological and pathogenic characteristics of foodborne illness in Shiyan in 2019 and provide targeted measures for the prevention and control work of the foodborne illness． Methods The active surveillance data of foodborne illness in shiyan in 2019 were collected and analyzed. The Salmonella strains isolated from the patients with foodborne illness were tested with serotyping，PFGE molecular classification and drug sensitivity test respectively according to《National foodborne illness surveillance workbook 2019》. Result A total of 3 191 cases of foodborne illness were analyzed. The pre-school children were the highest-risk group of foodborne diseases. Grain and grain product was the main suspicious contaminated food．The main location of eating place was family. A total of 330 samples were tested. The positive detection rate of foodborne illness was 20.30%（73/330）.The main pathogen were Rotavirus and Salmonella,and the detection rates were 11.21%(37/330) and 4.85%(16/330) respectively. The pre-school children were the group with the highest detection rate, which was 57.27% (63/110). The dominant serotype of the 14 Salmonella strains isolated from patients were Salmonella typhimurium and Salmonella enteritis. 14 different genotypes were obtained through PFGE classification and clustering. 64.29% (9/14) of Salmonella strains were multidrug-resistant strains. The drug resistance rates of ampicillin and tetracycline were the highest, which were 71.43%（11/14）and 64.29%（10/14）respectively. Conclusions The publicity and education of food safety should be strengthened and the surveillance network system of food-borne disease should be further improved according to the epidemiological and pathogenic characteristics of foodborne illness in Shiyan in 2019, and the use of clinical antibiotics should be controlled reasonably as well.
