Last trip to the grocery store I couldn’t find any non-US salad kits, and Silk NextMilk is made down there now, because I guess our plants were the listeria ones. Chip dip was surprisingly hard to find too, although I did it.
I’m very pleased with how many vegetables actually come from Mexico (definitely via the US though), and there’s even a few things you can get from greenhouses, so that situation is less dire than I’d expected.
