I heard that too. Suffice it to say a bunch of very dear pets have died due to damned globalization.
Yes...that is the reason why freezing dry food for 24 hours after bringing it home, there are bugs in it that also thrive in flour products while in storage or shipment...its the same bug critters that get in the pet food and flour products. My vet told me this years ago, I have not had problems since...so far no problems with my critters, with this "new" illness' either.
