Iowa regulators attack pet foods, supplements

Des Moines-Pet Food Institute (PFI) officials are, at presstime, scheduled to meet with Iowa regulators in an attempt to squelch a proposed Dec. 1 ban on animal diets containing nutritional supplements such as glucosamine and chondroitin.

The state agriculture department's sudden crackdown on all products sold in Iowa containing nutritional supplements not regulated by the Food and Drug Administration (FDA)has the pet food industry reeling, says Nancy Cook, vice president of technology and regulatory affairs with PFI, a trade group representing at least 30 pet food manufacturers. The attack is aimed at foods containing ingredients that purportedly ease joint problems, boost immune systems or ease digestive ailments. State officials argue there's been no scientific proof concerning these supplements' efficacy. They also threatened to bar animal health supplements, but regulators reached an agreement with the industry to exempt products as long as they are not mixed with feed and make label changes purporting no nutritional claims, says John Whipple, bureau chief with the Iowa Department of Agriculture & Land Stewardship.

"These nutritional supplements come under our jurisdiction because the FDA hasn't addressed the issue," Whipple says. "We never intended to take these products off the market, but we must regulate everything we consider animal feed. If the FDA wished to take the same hands-off approach with animal supplements that it does on the human side, there wouldn't be an issue for us. "

Supplements can be found in several pet food brands sold in Iowa, including Hill's Science Diet for senior dogs and Iams Large Breed formula - two national top sellers often recommended by veterinarians. The Iowa Veterinary Medical Association (IVMA) urges state officials not to make any blanket decisions.

Off the market?

"It's a real thorny issue," IVMA Executive Director Dr. Tom Johnson says. "We understand the state's concerns and we're all for taking off products that are harmful, but we know that some of these products are safe and effective.

"If the FDA would take a stand on this issue, it would make it a lot easier for everyone, but right now it's a bit frustrating. We're just going to have to wait and see what happens."

Industry officials worry the outcome in Iowa could spark a ripple effect nationally.

Going national

"When one state takes it this far, who knows where the others will follow," Cook says.

Whipple acknowledges that at least four other states currently are looking into the issue.
