We've built a society that's so litigious that companies are incentivized to recommend throwing away food even if there's less than a 0.01% chance of food-borne illness. Our waste is in part out of fear of getting sued or sick, but I'm not convinced the waste is the lesser of two evils. Food poisoning sucks, but it's survivable. Unlike starvation.

A good example of this caution is eggs and refrigeration, for which American's and European's have opposite ways of handling things.
