We were talking about this yesterday, my uncle got it in Texas. They’re pretty sure that they came from Mexico.
We were also talking about a big company in Arizona who can’t get enough workers and are exporting to Mexico and then re-importing to the US but I think it is too early for Arizona to have tomatoes.
Whole Foods is HQ in TX.... they re-called their Roma and “large field grown” tomatoes.
