Food safety is part of public health and disease prevention. Food safety is taught in medical school, typically as part of a microbiology or infectious disease course, and there are entire departments that deal with it at local, national, and international public health agencies. Appropriately, we have a food-safety tag. The tag should probably get some attention and a definition, but it is DEFINITELY a medical science.
The question at issue here doesn't show the best research effort, but but appears to be an honest question, and has a good, accepted answer, and is definitely on topic.
I've nominated the question for re-opening. Please re-open it and don't hammer close food safety questions. Food safety/foodborne illness is on topic according to our definition of medical science.
To clarify, if you are of the very odd opinion (to someone who works in infectious disease and public health) that food safety is somehow not public health, disease prevention, or medical science, you may be interested to know that it is "on topic" at the NHS, CDC, WHO, PHAC, Australian Department of Health, and literally every public health agency I've ever worked with.
