Pentobarbital in Pet Food. A dirty little secret is now out in the open

Talula died on New Year’s Day, 2017, a casualty of pentobarbital-adulterated pet food.

Pentobarbital is the active ingredient in the sedative Nembutal. People who rely on this habit-forming drug over a long period of time develop a tolerance to it, requiring ever-higher doses to achieve the desired sedative effect. Veterinarians use pentobarbital both as a sedative and as a humane euthanasia agent.

In the 1990s, several veterinarians contacted the U.S. Food and Drug Administration (FDA) to express concern that some of their companion-animal patients had become less responsive to the drug. They worried that the animals might have developed tolerance to the effects of pentobarbital as a result of chronic exposure to low levels of the drug in pet foods.

The FDA Digs In

Reacting to the red flag raised by the veterinary community, the FDA surveyed a selection of dry dog foods (kibble) for pentobarbital residue in 1998 and again in 2000. The 1998 survey included 90 individual samples from 49 different kibble varieties and 17 different brands. Twenty-nine of the 49 products were found to contain pentobarbital, with nearly 50 percent of the 90 individual samples testing positive for the drug.

In the second survey, which began in December 2000, the FDA screened 60 samples of kibble for pentobarbital, this time also measuring how much of the drug was present in the contaminated samples.

Compared to the 2000 survey, the one done in 1998 included more products with rendered ingredients near the top of the ingredient list, and the proportion of samples containing pentobarbital in the first survey was notably higher than in the second: 49 percent versus 18 percent. This led the FDA to conclude that pet foods containing higher amounts of rendered ingredients were more likely to be contaminated with pentobarbital.

Even a trace amount of pentobarbital is enough to establish that a pet food is adulterated. Nevertheless, the FDA took no regulatory action against the manufacturers of the pentobarbital-contaminated kibble identified in either survey. According to the agency, the level of pentobarbital in even the most highly contaminated sample was far below the amount that might make a dog ill.

In response to persistent rumors that the rendered remains of euthanized companion animals were being recycled into pet food, the FDA also tested pentobarbitalpositive samples from the 2000 survey for the presence of cat or dog DNA. Results were negative, and the agency concluded that the rendered remains of euthanized cattle or horses were the most likely sources of the pentobarbital contamination.

Rendering is the practice of using heat to extract useable fat and protein from animal carcasses, animal by-products and foodprocessing waste (such as used cooking oil). With a few exceptions, products of rendering are not considered fit for human consumption. However, they may be used as ingredients in animal feeds and pet foods as long as they do not contain any poisonous or harmful contaminants, such as pentobarbital.

The Evanger’s Affair: A Tangled Web

Pentobarbital was back in the news in 2017. Evanger’s Hunk of Beef au Jus canned dog food was linked to the death of Talula, and to the illness of four other dogs who had been fed from the same can. A massive quantity of pentobarbital was found in samples of the pet food, and the drug was also recovered from Talula’s stomach contents on necropsy.

Where did the pentobarbital come from? No rendered ingredients were listed on the product labels, and Evanger’s claimed to use “USDA-inspected, human-grade” beef in its products.

Evanger’s label claims were called into question when FDA investigators examined bills of lading and invoices from Bailey Farms, Evanger’s principal supplier of beef. The paperwork described the meat as “Inedible Hand Deboned Beef. For Pet Food Use Only. Not Fit For Human Consumption.” In addition, some samples of Evanger’s canned dog food contained trace quantities of horse meat. (Horse meat is permitted in pet food as long as its presence is disclosed in the list of ingredients.)

Evanger’s management pounced immediately on the horse-meat finding, insisting the company had been misled, and that Bailey Farms must have supplied Evanger’s with meat from chemically euthanized horses, mislabeling it as beef. The horse meat, Evanger’s claimed, was the source of the pentobarbital found in the canned dog food.

In response to urging from the FDA, Evanger’s voluntarily recalled a limited quantity of Hunk of Beef on February 3, 2017. On March 3, citing an “abundance of caution,” Evanger’s expanded its initial recall to include every batch of Hunk of Beef, Braised Beef and Against the Grain Pulled Beef canned dog foods manufactured between December 2015 and January 2017. (The “Against the Grain” brand name is owned by Nutripack LLC. Both Nutripack and Evanger’s are owned by members of the Sher family.)

According to the company, the March recall encompassed all of the products that contained meat supplied by Bailey Farms. By mid-April, this assurance was proved hollow. Pentobarbital was found in two Cocolicious canned dog-food products manufactured in 2015 by Evanger’s for Party Animal, a small California-based company. On April 24, Party Animal announced a recall of both products.

The Beef Tallow Connection

The Evanger’s incident prompted media outlet WJLA to commission a survey of other canned pet-food brands for pentobarbital contamination. The results of that survey rocked pet owners: in 2018, WJLA reported that several Gravy Train canned dog foods were adulterated with pentobarbital.

The Gravy Train name is owned by Big Heart Pet Brands, a subsidiary of the J.M. Smucker Company. After an internal investigation, the company announced that the source of the pentobarbital was beef tallow from a single supplier. At first, Smucker and Big Heart Brands initiated a company-to-company product withdrawal of a range of products from retail stores. Eventually, the company issued a voluntary recall of all the affected products.

Beef tallow was blamed for yet another pentobarbital contamination episode in 2018, this time involving a limited quantity of Orijen and Acana kibbles manufactured by Champion Petfoods. The relatively low level of pentobarbital in the tallow was not considered to be a health hazard. Champion reacted promptly to quarantine the contaminated tallow and retrieve the potentially affected production lots from its distribution chain. Most of the product manufactured with the contaminated tallow never reached the retail market, and there was no formal recall.

Beef tallow, the fat extracted from rendered beef, is usually disclosed on pet food labels as “beef fat” or “animal fat.” By law, tallow intended for use in human food, pet food and animal feed must not be derived from chemically euthanized animals. In practice, the Evanger’s incident exposed a large hole in this regulatory dyke: the food industry and the FDA’s reliance upon an honor system to identify and segregate carcasses of chemically euthanized animals.

When FDA inspectors visited Bailey Farms in 2017, they were told that the company relied on its customers (i.e., the farms from which it picks up dead animals) to tell its drivers whether any of the dead animals had been chemically euthanized. The drivers were instructed to mark those carcasses with orange paint before loading them onto their trucks. The orangemarked carcasses were segregated from the other carcasses upon arrival at the rendering plant.

According to Bailey’s owner, Gregory Schiel, the company would prefer not to pick up chemically euthanized animals at all. However, Schiel expressed concern that some customers might falsely claim that chemically euthanized animals had died from natural causes in order to dispose of the carcasses more easily.

The Legal Fallout

The Evanger’s affair spawned several lawsuits, including at least two class action lawsuits.

Pet owners who purchased Evanger’s products filed a lawsuit against Evanger’s, Against the Grain, Nutripack and the Sher family’s management company, collectively alleging one dog death (Talula) and seven illnesses as a consequence of feeding a product manufactured by the defendants.

A pet owner who purchased the recalled Party Animal products filed a lawsuit against both Party Animal and Evanger’s, alleging that the Party Animal product made her dog seriously ill.

Party Animal sued Evanger’s and Nutripack.

Evanger’s sued Bailey Farms, its meat supplier.

Colony Insurance Company sued Evanger’s, Nutripack and the class representatives in both class action lawsuits. In its filing, Colony Insurance claimed that Evanger’s owners had lied on the insurance policy application, thus voiding the policy.

The Gravy Train incident resulted in a class action lawsuit against Big Heart Brands. Collectively, plaintiffs in that lawsuit alleged 27 pet deaths (26 dogs and one cat) and two illnesses in pets fed one or more Big Heart canned dog foods.

At the time of the pentobarbital revelation, Champion Petfoods was also defending itself from a class action lawsuit based on alleged excessive heavy metal contamination. The plaintiffs added pentobarbital contamination to the existing complaint.

Of the 28 pet deaths alleged by the plaintiffs in the various lawsuits, only Talula’s death was lab-confirmed to have been due to pentobarbital contamination in a commercial dog food. In the other 27 deaths, the reported symptoms matched those associated with pentobarbital, but the food was not tested at the time the pets fell ill, and in most cases, necropsies were not carried out.

All of the lawsuits are still pending.

JBS knowingly distributed pentobarbital-adulterated products

JBS Souderton Inc. continued to distribute pentobarbital-adulterated products to customers even after receiving formal notification of pentobarbital contamination, according to a warning letter issued on April 23 by the Food and Drug Administration.

The warning letter to JBS Souderton Inc., which does business as MOPAC, was sent more than one year after pentobarbital was first discovered in beef tallow from the company’s Souderton, PA, facility.

Pentobarbital is a barbiturate used by veterinarians to euthanize animals, including companion animals, horses and cattle. According to the FDA, pet foods containing even a trace amount of pentobarbital are considered adulterated. It is against federal law to release “adulterated” products into the stream of commerce.

JBS was the supplier of beef tallow to Big Heart Pet Brands Inc. and to Champion PetFoods, among others.

Big Heart is a wholly owned subsidiary of The J.M. Smucker Company Inc. Champion is a Canadian pet food company whose U.S. production facility is in Auburn, KY. It manufactures Acana and Orijen brands of dry dog food.

In February 2018, a media outlet reported having found pentobarbital in several samples of Gravy Train canned, wet dog food. Smucker initiated a product withdrawal of the implicated products pending the outcome of its internal investigation. 

Concurrently, FDA alerted pet owners about the possible presence of pentobarbital in the several dog food brands, including Gravy Train, Kibbles ’N Bits, Ol’ Roy and Skippy.

Smucker converted its withdrawal into a full-blown recall once company officials had confirmation of the presence of pentobarbital in its finished product and in samples of beef tallow supplied by JBS.

As part of its investigation into the Big Heart, FDA and the Pennsylvania Department of Agriculture conducted a joint inspection of JBS beginning March 13, 2018.

According to the warning letter, FDA found pentobarbital in four out of nine samples collected at the JBS facility. Upon further analysis, three of the samples were found to contain pentobarbital at levels ranging from 61.8 +/-19 to 277 +/-70 nanograms per gram (ng/g), well above the minimum detection concentration of 4 ng/g.

The four pentobarbital-contaminated products were delivered to customers from November 2017 through March 2018.

Samples collected from JBS and from its customers’ facilities and analyzed by Pennsylvania officials found levels of pentobarbital as high as 680 ng/g.

The list of Inspectional “Observations” in the FDA’s Form 483, provided to JBS management on Oct. 17, 2018, contained two items:

  1. JBS did not visually verify loads of raw materials with what the hauler stated that they brought in. This led to tallow, manufactured at [the JBS] facility, to be adulterated with pentobarbital.
  2. JBS did not have an effective system for evaluating incoming raw materials to ensure that these ingredients are suitable for use in human products and animal feeds.

JBS officials informed the FDA on April 17, 2018, that the company had completed cleaning all of its conveyances, conduits, cookers and centrifuges, and some of its storage tanks to remove any pentobarbital-contaminated product. In a May 30, 2018, letter, JBS management indicated the company would complete the cleaning process within an additional 30 days.

The company officials also reported having identified and talked with all of its suppliers that may have presented a risk for entry of euthanized animals into the rendering plant, and obtained a guarantee from each supplier that they would not provide euthanized animals. JBS also indicated it would continue to conduct random tests of tallow products for pentobarbital.

On July 27, 2018, the FDA took a follow-up sample from one of the JBS storage tanks. Upon analysis, the sample was found to contain trace amounts of pentobarbital.

On Aug. 8, 2018, the FDA inquired what actions JBS planned to take in response to the pentobarbital finding. 

The company declined to recall the product. Instead, JBS offered to ask animal food producing customers that received animal food products to remove any products deemed positive for pentobarbital and to have their tanks cleaned.

JBS described its product withdrawals and attempted withdrawals of pentobarbital-contaminated product from its customers in a Nov. 26, 2018, letter to the FDA. 

In its warning letter, the FDA noted that it was unable to asses the effectiveness of the corrective actions in the absence of a voluntary recall or other documentation demonstrating all contaminated products were removed from the marketplace.

As reported by Food Safety News in November 2018, Champion PetFoods retrieved pet foods the contaminated tallow from its third-party distributors. The company declined to initiate a retail-level recall, even though some of the product had reached the store/consumer level. The refusal was based on laboratory test results on retained samples of those finished products that did not reveal pentobarbital.

JBS was given fifteen working days to notify the FDA in writing of the specific steps it has taken to correct the violations listed in the warning letter, or to provide a time frame within which the corrections will be completed.

Pentobarbital continues to ‘dog’ pet food industry; beef tallow blamed

This story by Phyllis Entis first appeared in Food Safety News and is reposted here with permission.

On May 8 Champion Petfoods USA Inc. was informed that three shipments of beef tallow delivered by their supplier were contaminated with pentobarbital, a tranquilizer often used to euthanize sick or fatally injured animals.

Ingestion of the barbiturate can cause drowsiness, dizziness, excitement, loss of balance, or nausea, or in extreme cases, possibly death of dogs and cats. Beef tallow is promoted as an inexpensive, palatable, and stable source of energy, with a nutritional profile “sufficient for safe use as a pet food ingredient,” according to an industry website,

Champion, a Canadian pet food company whose U.S. production facility is in Auburn, KY, manufactures Acana and Orijen brands of dry dog food.

The company ceased manufacturing products that require beef tallow, and quarantined the three pentobarbital-contaminated lots of tallow. However, by the time the company learned of the problem, some of the tallow already had been used.

Champion initiated pentobarbital testing on the retained samples from the beginning, middle and end of the affected production lots, and retrieved finished product from its third-party distributors.

The retained samples tested for pentobarbital were found to be negative. Some of the finished products containing contaminated tallow were distributed to the store/consumer level, but no retail-level product recall was initiated.

On May 16 the Food and Drug Administration initiated an inspection of Champion’s facility, according to information contained in the agency’s Establishment Inspection Report (EIR), which was obtained by Food Safety News in response to a Freedom of Information Act request.

During the inspection, the company informed FDA that Champion was no longer doing business with the Pennsylvania supplier of beef tallow and consulted with the agency on how to properly dispose of the pentobarbital-contaminated tallow.

The name of Champion’s tallow supplier was blacked out in the EIR.

Champion advised FDA inspectors that it will require its new supplier of tallow to include test results for pentobarbital on Certificates of Analysis accompanying all shipments of the ingredient. FDA investigators appeared satisfied with Champion’s response to the contaminated tallow episode, classifying the outcome of the investigation as “No Action Indicated.”

Since the beginning of 2017, pentobarbital contamination has triggered the recall of canned pet foods manufactured by Evanger’s Dog and Cat Food Co. and Big Heart Brands.

The source of pentobarbital contamination in the Evanger’s products was never established.

Beef tallow was the apparent source of pentobarbital contamination in Big Heart Brands’ canned pet foods. According to information contained in a class action complaint filed against the manufacturer of Gravy Train and other canned dog foods, Big Heart’s tallow supplier was MOPAC, a Pennsylvania rendering facility belonging to JBS USA Holding Inc.

Big Heart Brands packs several popular brands of pet food that are distributed nationwide. Those brands include Gravy Train, Kibbles ’N Bits, Skippy and Ol’ Roy brands. Big Heart Pet Brands distributed the Gravy Train, Kibbles ’N Bits and Skippy dog food to retailers nationwide. Walmart Stores Inc. distributed the Ol’ Roy dog food.
