What is the essential criterion that determines catfish suitability for an animal-only eating plan?

Its suitability hinges on the absence of forbidden ingredients during processing or preparation.

For catfish to maintain its standing as a viable protein source within a diet restricting plant matter, its biological classification as an animal product is not the only factor. The critical determinant for compliance is the preparation and processing history. If non-animal components, such as vegetable-based additives, flavor enhancers, or binders used during commercial processing or seasoning, are present, the food item immediately falls outside the acceptable parameters of the animal-only plan.
