Exercise caution when relying on these kinds of reports.
When testing any (human or pet) food, the results can differ significantly from day to day based on the specific farm or batch used as a source for any one individual ingredient.
As with any laboratory study, it is absolutely critical to collect a statistically significant (large) number of test samples from multiple batches to avoid a misleading variable known as sampling error. Read about that here:

In addition, guidelines used for interpreting the results can also be change or manipulated. This can cause certain products to move from one rating category to another — and even from “best” to “worst” lists. Read about that here:

By the way, Champion Petfoods, the maker of Acana and Orijen, has recently (2017) been recognized by the Global Food Safety Initiative (GFSI) for its food safety program at the company’s new Kentucky DogStar facility. You can read about that here:

Hope this helps.
