Major dog food brands recalled over possible euthanasia drug contamination

The U.S. Food and Drug Administration issued an advisory on Friday warning pet owners about the possible presence of pentobarbital — a barbiturate commonly used to euthanize animals — in some canned dog food products.

The J.M. Smucker Company is voluntarily withdrawing shipments of several of its dog food brands, including Gravy Train, Kibbles ’N Bits, Ol’ Roy and Skippy. You can view a full list of the recalled products here.

The announcement comes after a Washington, D.C., news station investigated the company. WJLA-TV sent samples of wet dog food from more than two dozen brands to an independent lab to be tested for pentobarbital.

The investigation found that “one brand repeatedly came back positive for pentobarbital” — Gravy Train.

Gravy Train 13.2 oz. with T-Bone Flavor Chunks is one of the recalled varieties.

“In total, we tested 15 cans of Gravy Train,” WJLA said in its report. “Nine cans — 60-percent of the sample — were positive for pentobarbital. And while the levels detected were not lethal, under federal law they are also not permitted at any concentration.”

The FDA wrote that its own “preliminary evaluation” of Gravy Train samples suggests that the drug is not present at high enough levels to pose a health risk, but food containing any amount of pentobarbital is considered adulterated.

“The presence of this substance at any level is not acceptable to us and not up to our quality standards,” Gravy Train said in a statement. “We sincerely apologize for the concern this has caused.”

Dog flu symptoms

How can you tell if your dog is sick?

Dogs can be stoic and hide symptoms of disease very well, so sometimes it's hard to tell your companion is under the weather. Dr. Heather Dean of Colquitt Animal Hospital in Georgia says, "Infections can cause mild to severe illness in dogs. Some dogs may develop secondary bacterial infections which may lead to more severe illness and pneumonia." And with super common respiratory symptoms, dog flu can look like other, less serious illnesses, so it's important to address any abrupt changes or sudden onset symptoms as soon as possible. Find out the 50 secrets your dog won't tell you.

Dog flu symptom: Nasal discharge

An early symptom of canine influenza is a thick, yellow, or greenish nasal discharge. More than just a sniffle, this mucus can come on quickly and last as long as three weeks.

Dog flu symptom: Lack of appetite

While it may not be uncommon for some dogs to skip a meal, lack of appetite can also be a red flag for a more serious condition. If it's accompanied by any other abnormal behaviors or signs of illness, is unusual for your pet, or goes on for a few days, call the vet.

Dog flu symptom: Trembling or shivering

Often associated with cold, trembling or shivering is also a classic sign of fever and can also be a pain response. If your pooch has a case of the shivers but is not in a cold environment (and is not a chihuahua!), it could mean he or she has a fever.

Dog flu symptom: Lethargy

The flu can make even the most stalwart feel awful, and your dog is no exception. If your normally boisterous puppy is lying around, not interested in normal, day-to-day routines, he might be sick. Keep an eye on him and if you notice any other troubling symptoms or behaviors, it could be a symptom of dog flu.

Dog flu symptom: Increased body temperature

Normal body temperature for a healthy dog can be anywhere from 100 to 102 degrees Fahrenheit, so a temperature of 104 to 105 is notable. They will feel warm to the touch and their gums may be dry and tacky or bright pink. Do not give your dog over the counter human anti-inflammatories for fever, as ibuprofen, acetaminophen, and many other human medicines are deadly for dogs. If you think your dog has a fever, you should call your veterinarian. All dog owners should know these 12 foods that could kill your dog.

Dog flu symptom: Coughing

 The most common of all dog flu symptoms is a persistent cough. This type of cough can last anywhere from 10 to 21 days and is a hallmark symptom of canine influenza. Cough should not be treated with human cough suppressants as they can harm your pooch. Seek treatment from your veterinarian.

Dog flu symptom: Glassy eyes

Similar to humans, dogs can also develop a glassy-eyed stare when they have a fever. If you suspect your pet has a fever, talk to your vet.

Dog flu symptom: Sneezing

Just like in human flu, canine influenza causes upper respiratory symptoms, including sneezing. The accompanying nasal discharge can make sneezing messy and fairly constant through the duration of the illness.

Treatment

If you think your dog may be exhibiting dog flu symptoms, call your vet and schedule and appointment. When you arrive for your appointment, Dr. Dean recommends briefly leaving your dog in the car while you quickly let the receptionist know you're there. "The veterinarian may wish the pet to remain in the car until they can be moved directly into an exam room or take other precautions to prevent contaminating the lobby and infecting any patients who may be waiting to be seen." Ask the receptionist to call your phone when they're ready for you so you can sit with your dog in your car while you wait. Read these 50 secrets veterinarians won't tell you.

Prevention

If your dog is unvaccinated for canine influenza, avoid dog parks and groomers, boarding facilities, and doggie daycares. Clean all leashes and toys. Also, discuss whether the dog flu vaccine is appropriate for your pup. If your dog never leaves home and doesn't come into contact with other dogs, the vaccine might be unnecessary as risk of infection is low.

It's also important to know these warning signs of cancer in dogs.

It’s unclear whether all the recalled brands, or just Gravy Train, have actually tested positive for pentobarbital. HuffPost was unable to immediately reach a representative for The J.M. Smucker Company. 

Pentobarbital is commonly used for euthanasia, as well as for other medical purposes for both animals and humans. It’s also used to execute inmates sentenced to death. Possible harmful effects of pentobarbital in pet food include drowsiness, dizziness, nausea and — and at high levels — coma and death. Last year, a pug in Washington state died after consuming pentobarbital-contaminated dog food made by pet food company Evanger’s.

The issue raises the question, how is any pentobarbital getting into pet food in the first place?

Evanger’s linked its product’s contamination to a beef supplier and subsequently terminated the relationship. Gravy Train also said it traced its own problem to a single source — though the statement did not elaborate on what that source was.

“We have narrowed the focus of our investigation to a single supplier and a single, minor ingredient, used at one manufacturing facility,” the Gravy Train statement said. “We will take the appropriate steps to ensure this does not occur again.”

The brand also explicitly said that its products do not include meat from euthanized animals, including pets.

The company likely felt compelled to address that point, because pentobarbital in pet food often fuels speculation over whether cat and dog food may contain the bodies of euthanized cats and dogs. That’s because some pet food companies source ingredients from rendering plants, which grind up animal carcasses from an array of sources that can include farms, slaughterhouses, veterinary clinics and animal shelters. According to fact-checking site Snopes, the presence of dead cats and dogs in pet food has not been definitively proven.
