A recent study also found some pet foods contain toxic levels of arsenic, lead, mercury, and even nuclear waste.

This 'raw material' is often then bulked out with a filler, to make the 'meat' go further. This can be anything that is low cost on the world commodity market - sugar, sawdust, newspaper, nut shells, melamine, to mention just a few.

At some stage, preservatives are added, preservatives such as ethoxyquin or formaldehyde. Neither of these preservatives are allowed in human food because of their high toxicity. Sadly, few people care about animals. Animals can't vote. The few laws governing pet food are ineffective and rarely enforced, depending on the country. If the rendering plant adds the preservative, rather than the pet food manufacturer, they can legally claim they did not add it.
