No. My insight into mexican-grown produce is from the regional produce manager of a local...
...supermarket here in Phoenix.
He said he would never serve his family any produce grown on the ground in mexico. They irrigate their fields with questionable water. Sometimes it is untreated effluence.
Melons, squash, strawberries, and any root vegetables would be off his list.
If it hangs from a tree or a vine, it is probably alright.
