This I find incomprehensible. Are the people preparing that food wearing masks and gloves? If not, why would you even get it? Seems like a no-brainer to 1) put at least minimal PPE on the food handling employees, and 2) NOT buy it if they don't have that minimal PPE. I got gas this weekend, at a station with an attached fast food restaurant. When I passed by, I saw that at least the counter person, who was handling the outside of all the items (at a minimum), had no gloves on. Then she went over to one side and coughed. As Spock would say, "Fascinating." Or, maybe, "asking for trouble."
As an EE, I have worked in the semiconductor fab portion of my industry. I've worked/been in, oh, three university, two industry, and one military clean room. over the years. If you are doing Class 100 or Class 10, you don't half-ass that stuff and expect good results. I would expect a lot of parallels between medical/germ isolation and PPE, and semi fabs. What I see on a routine basis doesn't even come up to the standards of half-assing.
