The cause for the association between DCM and some grain-free commercial dog foods has not yet been determined.
Raw meat-based diets are more likely to be contaminated by bacterial pathogens like Salmonella and Listeria.
High pressure processing (HPP) can be an effective non-heating method for reducing bacterial pathogens in commercial raw & freeze-dried foods/treats, IF employed properly.
