Feels like you didn't read the article (the NYTimes one is way better).

This is Teflon before 2016. If you were close enough, it was in drinking water... water you would have used for growing your own food. Organics would have provided zero protection.

Unless you happen to live in an off-world colony, growing your own food will not protect you.

Unless you live in a totally closed eco-system, you share the same water, air, fauna and flora as anybody. So you should be concerned as well.

You grow all of your own food? You don't eat any food grown by any person except yourself?
