Any foods not allowed into Mexico

When I drove a truck the California check points were looking for a number of insects - not just fruit flies - it would depend on what part of the country I was coming from - they were particularly concerned about Gypsy Moths from New England and to my knowledge they have still managed to keep that plague out of California. There were other things they would look for from other parts of the country but at this point I can't recall exactly what. As we travel all over North America we do see insects in different parts of the country that we do not see in California - but we are not experts and do not claim to be. Now there is a checkpoint on every road going into California where they stop everyone no matter which state or where you are coming from and have fruit thrown out no matter where it came from. When we came in from Canada to the US last summer they made us throw our eggs away because of some avian flu I think. In Mexico there were checkpoints going into Chetumal where they made us throw away a number of things. I do certainly agree that some of the border requirements are ridiculous and definitely have to do with NAFTA never getting to where they agreed on the things they were suppose to agree on. Mexican trucks were not allowed into the US until recently because trucker unions in the US insisted Mexican trucks are not safe and Mexican truckers do not have the same licensing requirements - it took years to iron that out - but interestingly enough Mexican truckers do not want to enter the US. There are many reasons for border requirements in all directions and some are just nonsense and some are there for reasons only the experts will ever know.
