were in 4 different municipalities/towns within a single province. Hence, the provincial and federal COVID-19 restrictions and guidelines were the same for all."
The authors state "These results suggest that the risk of exposure from contaminated high-touch surfaces within a food retailer store is low if preventive measures and recommended sanitizing routines are maintained." I am not sure they can go this far in suggesting this. For one, there was no evidence suggested that any shopper was ill with the COVID virus, so it is hard to discuss survival. Two, there was no comparison on the degree of of application of preventive measures, so any conclusion should state that "it may have had an impact."
