According to the website, the FDA
“Requires that all animal foods be safe to eat, produced under sanitary conditions, contain no harmful substances, and be truthfully labeled…There is no requirement that pet foods have pre-market approval by the FDA but the FDA does ensure that the ingredients used in pet food are safe and have an appropriate function in the pet food”
- basically, the FDA has already established that products such as meats, grains and vitamins (common ingredients in pet food) are generally safe and therefore, pet food containing any combination (WNL) of these products do not need to be inspected before going on the market.
The website also says that there has been a significant increase in the importation of pet food from China over the past ten years and a lot of the reported incidences of pet illness due to food (chicken jerky in particular) can be linked to products imported from China. Apparently they have conducted numerous lab tests to find out what is causing illness but as of yet, have been unable to find anything conclusive.
