Poultry feed (mash and pelleted) and meat and bone meal samples were collected from commercial mills. All samples were analyzed for Enterobacteriaceae count (ENT) and Salmonella. The genus and species of the various Enterobacteriaceae present were also determined. The average ENT for mash, pelleted, and meal samples was log 4.1, .8, and 1.8/g, respectively. Enterobacteriaceae were present in 100, 60, and 92% and Salmonella in 58, 0, and 92% of the mash, pelleted, and meal samples, respectively. Overall, the Enterobacteriaceae most frequently isolated from all samples were Enterobacter agglomerans, Enterobacter cloacae, and Klebsiella pneumoniae. Although no Salmonella were found in the pelleted samples, the presence of other Enterobacteriaceae suggests that commercial pelleting may not totally destroy Salmonella since their heat resistance is similar to the other organisms found.
从商业工厂采集了家禽饲料（粉料和颗粒料）以及肉骨粉样本。对所有样本进行了肠杆菌科计数（ENT）和沙门氏菌检测。还确定了所存在的各种肠杆菌科的属和种。粉料、颗粒料和肉骨粉样本的平均ENT分别为每克4.1、0.8和1.8对数。肠杆菌科在粉料、颗粒料和肉骨粉样本中的存在比例分别为100%、60%和92%，沙门氏菌的存在比例分别为58%、0和92%。总体而言，从所有样本中最常分离出的肠杆菌科是成团肠杆菌、阴沟肠杆菌和肺炎克雷伯菌。尽管在颗粒料样本中未发现沙门氏菌，但其他肠杆菌科的存在表明，商业制粒可能无法完全杀灭沙门氏菌，因为它们的耐热性与所发现的其他微生物相似。
