Even in China, when the corner-cutting that led to the melamine poisoning of milk products was discovered, several managers of the dairies responsible were executed. This is a good idea and should be adopted by Western cultures again. A person who has the potential to cause catastrophic losses of life by their greed or their negligence, should be treated as no less than a mass murderer.
Tie up the manager of that peanut plant and feed him his product until he shits himself to death. It would be poetic, epic, and totally unforgettable. It might even prevent further "economising" and corner cutting in the food industry...
