Grocery store employees are likely to be at heightened risk of COVID-19 infection, with those in customer-facing roles 5 times as likely to test positive as their colleagues in other positions, suggests the first study of its kind, published in the journal Occupational & Environmental Medicine.

Researchers studied 104 employees of one grocery store in Boston, Massachusetts. Each employee was tested for SARS-CoV-2.

Key Findings:

• One in five (21 out of 104) workers tested positive for SARS-CoV-2, indicating a prevalence of 20% at that point in time. This was significantly higher than the prevalence of the infection in the local community at the time: 0.9-1.3%.

• 3 out of 4 of those testing positive (76%) had no symptoms. And of those testing positive, most (91%) had a customer-facing role compared with 59% of those testing negative.

• Workers in customer-facing roles were five times more likely to test positive than their colleagues in other types of role. Those in supervisory roles were six times more likely to do so.

• Researchers point out: “Once essential workers are infected with SARS-CoV-2, they may become a significant transmission source for the community they serve.”
