Royal Canin Canada Recalls Additional Cat and Dog Food Due to New Toxin

UPDATE: The toxin found in these foods is cyanuric acid - not melamine. This is the first recall attributed to cyanuric acid.

Royal Canin has discovered a new contaminant in rice gluten. This contaminant is cyanuric acid, which is chemically related to, but distinct from, melamine.

ORIGINAL POST: Due to contaminated rice protein concentrate, Royal Canin has recalled the following cat and dog products from Canada on Friday:

  • Royal Canin Veterinary Diet Canine EARLY CARDIAC
  • Royal Canin Veterinary Diet Canine SENSITIVITY RC (Rice and Catfish)
  • Royal Canin Veterinary Diet Canine SKIN SUPPORT
  • Royal Canin Veterinary Diet Feline HYPOALLERGENIC HP
  • Royal Canin Veterinary Diet Feline SENSITIVITY RD (Rice and Duck)

These differ from the products pulled from the US. Two products, Feline Sensitivity RD and Canine Sensitivity RC are not currently recalled in the US. We do not know whether the food was made in Canada or the US. Therefore, it is also not clear whether the tainted rice protein went to Canada.

So far, Royal Canin has pulled products due to tainted wheat gluten, corn gluten and rice protein in the US, Canada, and South Africa. And is being sued for Vitamin D overdose.
Full release from Medi-Cal Canada homepage after the jump.

They have also promised to no longer use vegetable protein from China.

    I looked at a vitamin called NU KAT

    Correct me if I’m wrong but isn’t Menadione, which is listed in the vitamin as (a source of Vitamin K activity) . .0.002 mg - bad for cats? And… what is “chicken liver digest”. … which is listed in the liquid form?

    I cant stay & read today & I really need to, but Im hoping the right person will see this & pose this question to those that need to see it :
    This is the U.S.A. WHY are we paying our farmers in this country to NOT grow crops & importing wheat, corn & rice from china???????? Garbage wheat , rice & corn no less!!

  3. connie says:

    gumbi, NO pedigree is NOT recalled. mars makes pedigree. if you go to the pedigee website, the page says none of our products contain melamine, or (the a word) rat poison. Its my belief that pedigree is ok.

  4. connie says:

    last one. I as well get more & more confused every day. this weekend I went shopping for something, anything that was made with domesically grown ingredients. If your feeding dry, the most accessable I seem to have found with .u.s. grown ingredients is dads pet food. read the labels though if you have diabetics. 2 of the dry dog contained corn syrup!. all 21 of my hairy kids are eating dads this week, when they eat dry

    Great question about farming! I’ve been asking that question for years. Whats wrong with growing what we need right here. I can’t figure it out either!

  6. Judy says:

    Fromm manufactures food in China because it is cheaper than making it here! Do really believe that most of these pet food manufactuer’s care two hoots about your pets health? It is all controlled by the Almighty Dollar.
    Do you want your food coming from a place in the world with a seriously toxic environment! No controls on the feed ingredients? The food is grown there also. Kids go to school wearing respirators, because of the toxicity and bad air. I don’t want my pets eating that crap and I don’t want to eat any food coming from China either.

  7. Judy says:

    Pedigree is basically corn. You are better off with the Life’s Abundance.
    It is formulated by a vet who really cares about cats. I think it may be one of the better ones out there. NO gluten of any kind.
    Yes, their canned food was made at a MF plant but not the one that was turning out the bad food. And the canned food doesn’t have any gluten either.
    Canidae/Felidae is also a good choice, as is Chicken Soup. I don’t like all the trendy, unnecessary ingredients in some of them, but at least they are safe.
    Iams and Eukanuba are also safe. High, meat protein, no gluten of any kind.

  8. Gumbi says:

    Thank You very much to the ones who responded! I’ll keep all the furry pets in my prayers…….this whole thing is sad, frustrating and most of all UPSETTING!

    My cat is recovering, I have always fed raw meat (Beef) at night, dry food all the time, and canned twice a day. I now feed some dry, raw grounded turkey, raw beef, same as they feed the greyhound racing dogs, range fed from here in Colorado. And cooked pork. I spoke with my Chinese doctor, who has a 20 year old little dog, and he says he feds him chicken and pork from the Asian markets. The meat is much fresher and costs less. So I went and got two large chunks of pork, cooked it and the cats love it. For $7.00 I have eight feedings and I have over 10 cats. The turkey is from Costco. I lost 50% of my bees this year to all the problems of artifical items being put on grasses in yards and other areas. We must change our pets and our eating habits and go back to natural. Here in Denver, the farm lands are being cut off from water so they can build more houses, we also have one of the highest foreclosure rates in the county. But the builders have no hearts!

    What am I supposed to do with the Nutro 3oz. cans I have that were recalled? Should I bring them back to the store? All my cats seem to be OK at least on the outside except my Tortie so far anyway. I have been holding off but don’t want them hanging around to remind me that even food that wasn’t supposed to have by-products etc. was produced not by Nutro but Menu.

    I posted this elsewhere on Itchmo but not in a Royal Canin thread so here goes… I lost my cat on 07 Jan. He was perfectly healthy (so I thought) until the a.m. of 06 Jan and then throughout the day declined in health to the point where I rushed him to the emergency vet in Montreal. He’d been to another vet in the a.m. who had diagnosed “constipation” (!!!) and sent us home with a bottle of Lactulose. When we got to the emergency vet he was admitted right away but his vitals declined so rapidly that the vet completely freaked out. He died of his own accord 3 hours after being admitted (we didn’t even have time to consider putting him down - we were still trying to find out what was wrong with him). An autopsy and subsequent anticoagulant panel at Michigan Labs in the US showed a large amount of Diphacinone in his liver (yes… rat poison). I’ve been arguing that result ever since, because we don’t have rat poison in our house and my cat was exclusively an indoor cat for the seven years of his short life. Fast forward to the Royal Canin Sensitivity RD recall last week - at that point I sent my cat’s autopsy and emerg vet report to Medi-Cal with a request to get back to me. Within days I had a call from a vet telling me that yes, it was very likely that the food had killed him (he had been eating this dry food for most of his life). As in a similar posting I see here, the vet asked for no proof of purchase (I have it) but said all bills will be paid. I’m planning on billing them for my cat’s cremation as well - at least I was sure he wasn’t making it back into the pet food supply chain - not to mention the emotional comfort it gave me to know he was treated honorably even at the end.

    I also checked the symptoms of cyanuric poisoning in humans (closest I could get) and they mirror exactly what my cat went through, including rapidly advancing hypotension, lesions on the organ, organ failure (esp. kidneys/liver). My question to the Medi-Cal vet (and Medi-Cal is calling Michigan Labs) is whether or not they could have mistaken the Diphacinone result for cyanuric acid… something for which they would not have been checking last January.

    Symptoms of Cyanuric Acid Poisoning in Humans
    · Lungs
    o Breathing difficulty (from inhalation)
    o Throat swelling (which may also cause breathing difficulty) (yes)

    o Severe abdominal pain (yes)
    o Vomiting (may contain blood) (yes)
    o Burns of the esophagus (food pipe)
    o Nausea (yes)
    o Blood in the stool (cannot say – by the time we noticed him he could no longer empty his bowels)
    · Heart and blood
    o Hypotension (low blood pressure) develops rapidly (yes)
    o Collapse (yes)
    · Skin
    o Irritation
    o Burn
    o Necrosis (holes) in the skin or underlying tissues
    · Blood
    o Too much or too little acid in the blood - leads to organ damage (?)

    I do not mean to be insulting, but there are a lot of really, really uninformed comments being made on this site. I doubt most would have a real problem knowing the difference between an HPLC and an ICP-mass spec. People need to understand some of this chemistry is just as tough as rocket science. And there are the Chicken Littles linking this to Monsanto GM corn et al. And those thinking that adding cyanuric acid as an economic way of boosting reported protein levels? Gimmee a break. No wonder some cats are the way they are with owners like this.

    Only the wealthiest of individuals could afford food tested to the levels that would satisfy the readers here. And the science just has not been developed. Just look at the Lance Armstrong and Floyd Landis testing problems where at least the class of drug is known. In the pet food problem, narrowing the class is tough. I challenge those complaining to do their own testing and let the rest of us critique your results. And what happens if this were a viral rather than a chemical adulterant? I doubt this is the case here but what if?? Perhaps then you will begin to appreciate the complexity of the problem. This is not a one hour episode of Miami CSI folks.

    I believe much of the problem rests upon sourcing ingredients from secure, trusted suppliers. The quest for pinching pennies to stay in business has forced mfgs to seek new suppliers. Again, no mfg can viably test for ALL aldulterants.

    Thirty years ago it would be unusual to see a 20 year old cat in a vet’s office. Now it is quite common and they are in good health. I guess this is the result of all of the tainted food.

    as for me:
    pessimistic optimist, sometimes cynic
    chem engr w/o links to industry
    dad is a retired mixed practice vet
    guardian of 4 19 & 20 yr old cats (until recently)

    I have two cats with diarrhea, one also vomiting for 4 days and is currently in the hospital being rehydrated. The second cat began diarrhea 12 hours ago. We noticed a mild garlicky smell from the Medi-Cal Preventive canned food (Exp 2010 JL 17) over the past few days. Has anyone else experienced this situation?
