Two Meanings of Safe Food
Surfing around the internet, I see several links to lists of "safe" peanut products. And we've seen food companies rush to label their peanut butter as "safe." But I think there are two different meanings to that word.
One meaning is 100% guaranteed, no risk whatsoever "safe."
The other meaning I'll illustrate with a little story. Imagine that you are going to hire somebody to drive your elderly parents and their grandchildren -- your children -- to Florida. You want a safe driver. You find a friend who is willing. You have ridden in the car with this friend many times. She has always driven very cautiously. Your friend has never had a ticket. Your friend has a very safe car which is well-maintained. Your friend doesn't drink. Your friend is unaware of any medical conditions that could cause trouble while driving. Anyway, you get the idea -- your friend is a "safe" driver.
So you ask your friend -- Will you guarantee me 100% that you won't get in an accident on the drive to Florida? Of course, the answer to that question is no.
I think most of our food meets the "safe driver" definition of safe. (Not enough, but the overwhelming majority.)
I don't think any of our food meets the 100% no risk definition. Never has. Never will.
