It is true, BUT, (and this is a big but, almost a baby got back but) the risk is not the same for improperly handled vegetables vs. meats or seafood. Poorly handled veggies generally will give you E. Coli, or a similar sort of nasty stomach/food illness.

Bad seafood can give you parasites.

It’s like the risk of surfing vs. the risk of driving a wave-runner. Both can injure you on the water but a bad wave-runner accident might kill you.
