近年来,由于单核细胞增生李斯特菌污染,已经召回了许多冷冻蔬菜产品,导致李斯特菌病.在孕妇中,李斯特菌病会导致流产,死产,和其他严重的并发症。制定制造指南的目的是在食用前煮熟冷冻蔬菜。然而,消费者可以在没有事先烹饪的情况下准备和食用冷冻蔬菜。因此,有必要评估可能对单核细胞增生李斯特菌暴露有风险的行为。对18-54岁的女性进行了10个问题的在线调查,以调查冷冻蔬菜的消费行为。未煮熟的冷冻蔬菜消费的普遍性,阅读准备说明,并评估李斯特菌病知识。使用逻辑和有序logit回归分析数据。在1001份完整的回复中,531(53%)表示他们在过去一周内食用冷冻蔬菜,其中35.6%(n=189)表示他们在没有事先加热的情况下食用冷冻蔬菜。没有听说过李斯特菌病和没有阅读准备说明的女性食用未煮熟的冷冻蔬菜的几率明显更高(赔率比(OR):2.30,95%置信区间(CI):1.48,3.55;OR:1.85,95%CI:1.13,3.01,分别)。这些结果将指导未来对冷冻蔬菜产品的安全食品处理实践的研究。研究结果支持需要更新公共卫生指南,将冷冻蔬菜作为妊娠期李斯特菌病风险的食物。此外,这些发现对未来的研究有意义,以告知食品政策,管理冷冻蔬菜产品的标签法规,以反映当前的消费者行为。
In recent years, there have been numerous recalls of frozen vegetable products due to Listeria monocytogenes contamination, which causes listeriosis. In pregnant women, listeriosis can cause miscarriage, stillbirth, and other serious complications. Manufacturing guidelines are created with the intention that frozen vegetables will be cooked prior to consumption. However, consumers may prepare and eat frozen vegetables without prior cooking. Therefore, it is necessary to assess behaviors that could be risky for L. monocytogenes exposure. A 10-question online survey was distributed to women between the ages of 18-54 to investigate frozen vegetable consumption behaviors. The prevalence of uncooked frozen vegetable consumption, reading preparation instructions, and listeriosis knowledge was assessed. Data were analyzed using logistic and ordered logit regression. Of 1,001 complete responses, 531 (53%) indicated that they consumed frozen vegetables in the past week, and of those 35.6% (n = 189) indicated that they consumed frozen vegetables without prior heating. Women who had not heard of listeriosis and had not read preparation instructions had significantly higher odds of uncooked frozen vegetable consumption (Odds Ratio (OR): 2.30, 95% Confidence Interval (CI): 1.48, 3.55; OR: 1.85, 95% CI: 1.13, 3.01, respectively). These results will guide future research on safe food handling practices for frozen vegetable products. The findings support the need for updating public health guidelines to include frozen vegetables as foods that are risky for listeriosis in pregnancy. Additionally, these findings have implications for future research to inform food policy governing labeling regulation on frozen vegetable products to reflect current consumer behavior.
