Although health units have implemented food handler certification to operators of food premises, evidence on its effectiveness to improve premise food safety remains inconclusive. Regression models were constructed using inspection data from a health unit in Ontario, Canada, to measure the effect of certification on premise inspection results. We found that premises without certified food handlers at the time of inspection were significantly more likely to fail inspections. The odds of inspection failure were significantly different depending on the premise's cultural cuisine classification. Independently owned establishments had lower odds of inspection failure versus chain operations. Inspector was a significant random effect explaining a small percentage of data variations. These results support the use of food handler certification to improve food safety outcomes at establishments. Further efforts should ensure training programs are accessible and relatable to premise operators, particularly those serving all types of cultural cuisines.

食品加工商认证对加拿大安大略省食品经营场所的影响。

尽管卫生部门已对食品经营场所的经营者实施了食品处理者认证，但其在改善场所食品安全方面的有效性的证据仍然没有定论。回归模型是使用加拿大安大略省卫生单位的检查数据构建的，以衡量认证对现场检查结果的影响。我们发现在检查时没有经过认证的食品处理人员的场所更容易未通过检查。检查失败的几率因场所的文化美食分类而有显着差异。与连锁经营机构相比，独立拥有的机构检查失败的几率较低。Inspector 是一个显着的随机效应，解释了一小部分数据变化。这些结果支持使用食品处理者认证来改善企业的食品安全结果。进一步的努力应该确保培训计划对经营场所的经营者来说是可访问的和相关的，特别是那些服务于所有类型的文化美食的经营者。
