On 13 May 2020, a COVID-19 cluster was detected in a French processing plant. Infected workers were described. The associations between the SARS-CoV-2 infection and the socio-demographic and occupational characteristics were assessed in order to implement risk management measures targeting workers at increased risk of contamination. Workers were tested by RT-PCR from samples taken during screening campaigns. Workers who tested positive were isolated and their contacts were quarantined. Workers were described and associations with the SARS-CoV-2 infection were assessed through risk ratios using multivariable Poisson regression. Of the 1347 workers, 87.5% were tested: 140 cases were identified; 4 were hospitalised, including 2 admitted to intensive care. In the company, the cluster remained limited to deboning and cutting activities. The attack rate was 11.9% in the company, reaching 16.6% in the cutting department. Being an employee of a subcontractor significantly increased the risk of infection by 2.98 [1.81–4.99]. In the cutting department, an association with virus infection was found for a group of non-French speaking workers from the same Eastern European country (RR = 2.67 [1.76–4.05]). They shared accommodation or carpooled more frequently than the other cases. The outbreak investigation revealed a significantly increased risk of SARS-CoV-2 infection for workers of subcontractors and some foreign-born workers. There are many such populations in meat processing plants; the observed associations and the ways in which these workers are contaminated need to be confirmed by further work. Prevention campaigns should now target these workers. Environmental risk factors in the workplace setting remain to be clarified.

2020 年 5 月,法国一家肉类加工厂爆发 COVID-19 疫情期间,识别感染风险增加的工人



2020 年 5 月 13 日,法国一家加工厂检测到了 COVID-19 集群。描述了受感染的工人。对 SARS-CoV-2 感染与社会人口和职业特征之间的关联进行了评估,以便针对感染风险较高的工人实施风险管理措施。工作人员接受了筛查活动期间采集的样本的 RT-PCR 检测。检测呈阳性的工人被隔离,他们的接触者也被隔离。使用多变量泊松回归对工人进行了描述,并通过风险比评估了与 SARS-CoV-2 感染的关联。 1347名工人中,87.5%接受了检测:确诊140例; 4人住院,其中2人住进重症监护室。在该公司,集群仍然仅限于剔骨和切割活动。公司内的攻击率为11.9%,切割部门达到了16.6%。作为分包商的雇员,感染风险显着增加 2.98 [1.81–4.99]。在切割部门,来自同一东欧国家的一组非法语工人被发现与病毒感染存在关联(RR = 2.67 [1.76–4.05])。他们比其他案例更频繁地合住或拼车。疫情调查显示,分包商工人和一些外国出生的工人感染 SARS-CoV-2 的风险显着增加。肉类加工厂中有很多这样的人群;观察到的关联以及这些工人被污染的方式需要通过进一步的工作来证实。预防活动现在应该针对这些工人。工作场所环境中的环境风险因素仍有待澄清。
