Tracy I'm not in Ithaca, but have a ferret friend going to grad school there. I'll forward your her email separately (she has told me before I can have people contact her). Performance Foods had problems with several batches of food last year. I suggest contacting them directly so they can look into this. It could be that the distributer or retailer did not store them properly, or it could be problems with whole batches again. From their web page, their phone number is 303.410.1101.
