It's been a year since the mess first started with the pet food recall. The recall lasted several months, and shed light on an industry that was unregulated, and in a lot of ways, didn't care much about the pets they were supposed to feed.
It also showed that the same company which was making the "commercial," i.e., inexpensive brands, was also making the high-priced premium brands that were supposed to help make your pet live a longer, healthier life....so much for that idea!
Unfortunately, there is still more work to be done in order to stop this mess from happening again. For example, the legislation that was passed requires the companies to voluntarily recall contaminated petfood. Voluntary doesn't work quite as well as mandatory.
Here is an interesting article about how things have fallen short.
