Banned growth chemical remains a problem in beef in central Mexico

Sorry, it's in pig and chickens, too. They don't inject. It's in the feed.

As a former agricultural researcher who used to work part time in Mexico: There are 2 kinds of agriculture in Mexico. One for export to the USA and big chain stores that requires producers to follow all the same residue tolerances as crops grown in the USA. These are usually big professional operations very similar to those in the USA. The little farmers use mostly cheap pesticides. They are cheap because they have been banned from the USA 15-20 years ago for toxicity, ineffectiveness, or environmental issues. I have been very shocked to learn what small farmers use here.
If you want to buy produce on the street without concerns for pesticide residues, pick stuff that is a bit eaten around the edges by worms.
