QUESTION:
I’m not sure I trust the big dog food manufacturers when their cans say “Preservative Free”, please can you explain what this means?
ANSWER:
As the law is currently written, manufacturers don't have to list preservatives that they themselves did not add. Many preservatives make their way into pet food at rendering plants before the meat is even sent to the manufacturer.
An analysis of several pet foods labeled "chemical free" or "all natural ingredients" found synthetic antioxidants in all samples. With continued use, low levels of these synthetic antioxidants may build up in the tissues; ingestion of small doses over time may be just as toxic as a single large dose.
About 60 percent of all herbicides, 90 percent of all fungicides, and 30 percent of all insecticides are considered to be cancer-causing in and of themselves – the average Labrador ingests as much as 26 pounds of preservatives from eating commercially-produced canned dog food every year.
