(Updated Dec 13, 2016. Valley Milk Products issued recall announcement on FDA website).
Valley Milk Products issued a recall of milk and buttermilk powder after FDA seized product due to the potential for Salmonella contamination. As reported a few days earlier, FDA seized product after an investigation found Salmonella in the environment, the same strains that had been hanging around for years. While FDA had urged the company to recall, they initially refused because they stated that testing had never found Salmonella in product. Well, FDA felt the environmental evidence was strong enough to warrant seizing product.
It is hard to guess the circumstances that were present to have this standoff, however, it does indicate that FDA will take action based upon conditions that might support adulteration, but not necessarily product contamination. In this case, the facility had some ongoing issues that should have been resolved, but the degree of risk is hard to guess.
