Summary What is already known about this topic?Salmonella causes acute and chronic diseases in food animals,and infected food animals are one of the most important source of human infection.What does this report contribute?The prevalence of Salmonella was 10.5%in chicken samples,24.4%in pig,23.3%in duck,and 29.4%in milk.Salmonella isolates were highly resistant to ampicillin(59.60%).What are the implications for public health practices?Data on Salmonella infections among food animals in China could help identify sources and factors related to the spread of Salmonella in food animals and food production chains. 展开更多

Antimicrobial resistance poses a significant threat to global public health,and excessive antimicrobial use(AMU)in animals is a major contributing factor.We used national AMU data for food animals to examine the current status and trends for AMU in food animals in China from 2018-2020.In 2020,China used 32,776.30 tons of antimicrobials in food animals,amounting to 165 g of antimicrobials per ton of animal products.AMU in China increased throughout the 2018-2020 study period;however,the data still showed a consistent and notable reduction from those of 2017,coinciding with the implementation of the China National Action Plan for Combating Animal Antimicrobial Resistance.Among the antimicrobials used,tetracyclines,macrolides andβ-lactams(includingβ-lactam inhibitors)were the most commonly used in food animals.Analysis by antimicrobial class revealed shifts in usage patterns,such as decreased tetracycline use and increased macrolide andβ-lactam use.Furthermore,the use of antimicrobial growth promoters decreased sharply,from 51.78%in 2018 to 28.7%in 2020.Compared with AMU data from other countries,China used more antimicrobials,but the values were relatively lower when adjusted for population correction units.These findings highlight China’s remarkable efforts in combating antimicrobial resistance and promoting antimicrobial stewardship,thus contributing significantly to global initiatives. 展开更多
