This article presents the surveillance data from the Feed Contaminants Program (2002-2009) and Salmonella Assignment (2007-2009) of the U.S. Food and Drug Administration (FDA), which monitor the trend of Salmonella contamination in animal feeds. A total of 2,058 samples were collected from complete animal feeds, feed ingredients, pet foods, pet treats, and supplements for pets in 2002-2009. These samples were tested for the presence of Salmonella. Those that were positive for Salmonella underwent serotyping and testing for antimicrobial susceptibility. Of the 2,058 samples, 257 were positive for Salmonella (12.5%). The results indicate a significant overall Salmonella reduction (p≤0.05) in animal feeds from 18.2% (187 samples tested) in 2002 to 8.0% (584 samples tested) in 2009. Among these samples, feed ingredients and pet foods/treats had the most significant reduction (p≤0.05). Of the 45 Salmonella serotypes identified, Salmonella Senftenberg and Salmonella Montevideo were the top two common serotypes (8.9%). Of the 257 Salmonella isolates obtained, 54 isolates (21%) were resistant to at least one antimicrobial. The findings provide the animal feed industries with Salmonella prevalence information that can be used to address Salmonella contamination problems. Our findings can also be used to educate pet owners when handling pet foods and treats at home to prevent salmonellosis.
本文呈现了美国食品和药物管理局（FDA）的饲料污染物计划（2002-2009 年）和沙门氏菌分配（2007-2009 年）的监测数据，这些数据监测了动物饲料中沙门氏菌污染的趋势。2002-2009 年期间，共从全价动物饲料、饲料成分、宠物食品、宠物零食和宠物补充剂中采集了 2058 个样本。这些样本经过沙门氏菌检测。对沙门氏菌呈阳性的样本进行血清分型和抗菌药物敏感性检测。在 2058 个样本中，有 257 个样本（12.5%）呈沙门氏菌阳性。结果表明，动物饲料中的沙门氏菌总体显著减少（p≤0.05），从 2002 年的 18.2%（187 个样本检测）降至 2009 年的 8.0%（584 个样本检测）。在这些样本中，饲料成分和宠物食品/零食的减少最为显著（p≤0.05）。在鉴定的 45 种沙门氏菌血清型中，沙门氏菌森滕贝格和沙门氏菌蒙得维的亚是最常见的两种血清型（8.9%）。在获得的 257 个沙门氏菌分离株中，有 54 个分离株（21%）对至少一种抗菌药物具有耐药性。这些发现为动物饲料行业提供了沙门氏菌流行情况信息，可用于解决沙门氏菌污染问题。我们的发现还可以用于在家庭中处理宠物食品和零食时教育宠物主人，以预防沙门氏菌病。
