Spycar,
You wrote ” I don’t think is too much to ask that slaughterhouses treat ingredient intended for pet food be treated respectfully and not to become grossly contaminated and spoiled by pathogens” What makes you think this isn’t already occurring? I think it likely in integrated plants but much more challenging to achieve in independent plants do to the types of materials they collect and the transportation involved.
Sure there may not be a law that prevents an integrated facility from accepting random sourced material but it makes no sense to do so and I don’t know that it is occurring at any frequency if at all.
In regards to by products you wrote: “The problem is how “by-products” are treated at slaughterhouses. They are treated as waste, often kept in hot offal trailers where they spoil and become contaminated and unwholesome and are consequently condemned for human use……”
You are painting with a very broad brush and implying by products are treated differently then muscle meat. At least that is how I read it.
In regards to “often kept in hot offal trailers”, have you found data which reports a percentage of material used in pet food is handled in this manner? What do you consider often?
