Bailey…the rosemary ingredient had been tested exclusively (2 ingredient food: ground chicken with rosemary, ground turkey with rosemary, etc.), as well as numerous food brands that contained rosemary. None of the testing foods contained vinegar & the only common denominator was rosemary. After 2 years of testing, it was determined that the cause of the vomiting and diarrhea was the rosemary (several specialty vets concur). Several high quality pet food manufacturers have food rosemary to be a reactive ingredient in their foods and have started to remive it, as well.
