In many areas of the Southwest, virtually all restaurant cooks are Mexican.
I remember when I first started seeing signs in public restrooms telling restaurant workers that the law required them to wash their hands after using the restroom. My first thought was, “They have to pass laws to get them to wash their hands after using the restroom and preparing food for the public? Gross!”
Well I don’t know why anyone would expect an illegal immigrant from a third world country to obey our laws. And sure enough they don’t. We have e coli recalls all the time and now this new (to me anyway) bacteria, Shigella is coming up. 200 people got sick! I looked up Shigella. It is passed through feces. Of course.
Try to eat at home if you live in the southwest or an area like it. If you have to eat out, try to go to a more expensive place that has White cooks and staff, if such a thing exists anymore. Sometimes the ma and pop shops are pretty good, if ma and pa are cooking.
