is a coagulase-positive pathogen of interest for human health and food safety in particular. It can survive in a wide environmental temperature range (7-48 °C, optimum 37 °C). Its enterotoxins are thermostable, which increases the risk of potential contamination in a variety of food products. Here we investigated the influence of seasonality and food type on bacterial count and presence of enterotoxins. To do this, we analyzed 3604 food samples collected over a 5-year period (2016-2020). Ordinal logistic regression showed an influence of both seasonality and food type on the bacterial count. Regarding bacterial counts, winter was found to be the season with the highest risk, while with regards to enterotoxin production, the highest risk was found in autumn, specifically in October. The risk of contamination with was greatest for dairy products. Our findings may inform food epidemiologists about foodborne illness prevention and risk to human health.
是一种凝固酶阳性病原体，尤其与人类健康和食品安全相关。它可以在很宽的环境温度范围内（7-48°C，最适温度为 37°C）生存。它的肠毒素耐热，这增加了各种食品中潜在污染的风险。在这里，我们研究了季节性和食品类型对细菌计数和肠毒素存在的影响。为此，我们分析了在 5 年期间（2016-2020 年）收集的 3604 个食品样本。有序逻辑回归显示季节性和食品类型对细菌计数都有影响。关于细菌计数，冬季被认为是风险最高的季节，而关于肠毒素产生，风险最高的季节是秋季，特别是 10 月。乳制品受污染的风险最大。我们的研究结果可以为食源性疾病预防和对人类健康的风险提供信息。
