Food Contaminators

A certain amount of food contamination is permitted by law: so many rat hairs per 100g of chocolate, so many pieces of insects per 100g of coffee, so many mouse droppings per 100g of peanut butter, etc. Any food maker whose contamination levels are under those of its competitors is at a clear economic disadvantage. After all, if the legal amount of freely produced mouse poo is not in the peanut butter you're selling, the missing portion must be - valuable peanut butter. Meanwhile, your competitors are padding their product with the legal mouse poo maximum.

My idea is to introduce a manufacturing process which would measure the food's contamination level, then add as many rat hairs, weevils, or what have you, as are needed. This would stretch out the commodities involved, perhaps even resulting in savings passed along to us consumers.

[Am posting this in the Food:Packaging section because the contamination would be performed during packaging; sorry, jutta, if this is the wrong place for this idea.]
