OK this is a bit disconcerting if you eat food at any major stadiums around the country. But it is interesting and worth a read.
An Outside the Lines analysis of 16,000 routine food-safety inspection reports covering 111 pro sports venues found that, at about 28 percent of the venues, half or more of their food service outlets incurred one or more high-level food-safety violations.

Without a doubt I think major venues like these need to start thinking about hiring more microbiologists. And maybe they should do more surveys of the microbes living in and on and around their facilities.
