Poultry feed and litter were contaminated with a large number of Salmonella typhimurium cells and then stored at 11, 25, or 38 C. Samples of feed and litter were cultured at daily or weekly intervals. The organisms survived best at the two lower temperatures. Persistence was as follows: at 11 C, at least 18 months in both feed and litter; at 25 C, 16 months in feed and 18 months in litter; and at 38 C, about 40 days in feed and only 13 days in litter. Hence, samples of feed and litter collected for bacteriologic examination should be stored at low temperatures.
家禽饲料和垫料被大量鼠伤寒沙门氏菌细胞污染，然后分别储存在11℃、25℃或38℃。饲料和垫料样本每隔一天或一周进行培养。这些微生物在两个较低温度下存活得最好。其持久性如下：在11℃时，饲料和垫料中至少存活18个月；在25℃时，饲料中存活16个月，垫料中存活18个月；在38℃时，饲料中存活约40天，垫料中仅存活13天。因此，采集用于细菌学检查的饲料和垫料样本应低温保存。
