That's not to say that they're nonexistent, though. Peanut butter, the snack food with some truly bizarre origins , can be contaminated during its production process.

When the producers who made it or the retailers who sold it found out that their products aren't up to scratch, they can be sent down the rabbit hole of a recall to prevent further harm. The causes of peanut butter recalls are pretty standard, but that doesn't mean that they're any less serious. Salmonella contamination can be a particular problem, and in the past has led to some massive recalls of the spread and associated products, with a few going down in history as being some of the most dangerous ever.
