Currently browsing posts about: Pet food

t foods are typically made from the by-products of human food production.  These, like offals, are plenty nutritious; we just don’t happen to want to eat them.  Pet foods therefore, reduces food waste.

A reader and friend, Patricia Gadsby, sent me this note:

Never occurred to me to ask this question before. But when the idea occurred I thought of you. What percentage of greenhouse gases are attributable to pet food? I found this.

Here’s the article she refers to:

Pedrinelli, V., Teixeira, F.A., Queiroz, M.R. et al. Environmental impact of diets for dogs and cats. Sci Rep 12, 18510 (2022). https://doi.org/10.1038/s41598-022-22631-0

The chief findings of this analysis of Brazilian pet foodss:

• Pet food has a high environmental impact.
• Wet diets have the highest.
• Dry diets have the least .
• The more animal protein, the higher the impact.
• The more calories, the greater the impact.

Like all environmental impact studies, this one depends on assumptions and tradeoffs.   The analysis does not consider the role of food waste., although the authors discuss this issue.

Several ingredients used in pet food are considered by-products, and this could be considered as a factor that reduces the impact of these foods…approximately 38% of beef, 20% of pork, and 19% of chicken is viscera or blood that is not used for human consumption31. Of all the by-products produced in Brazil, 12.8% are used in the pet food segment, and the rest is used for animal production, biodiesel, hygiene, and
cleaning, among other uses…In the present study, all types of diets contained by-products such as ofal or meat meals, although
dry and wet diets presented by-products more often than homemade diets.

I’m waiting for consensus on the assumptions.

In the meantime, two other items on pet food sustainability:

• Insect protein is a key solution to a sustainable pet food industry:  Government interest and funding are increasing for using insects to help meet climate goals.  .Read more

• Research reveals vegan diets can improve dog health: A study lead by Professor Andrew Knight at the University of Winchester in the UK found fewer cases of health disorders overall in dogs fed vegan diets.

Comment

Thanks to Phyllis Entis, author of TAINTED. From Farm Gate to Dinner Plate, Fifty Years of Food Safety Failures and TOXIC. From Factory to Food Bowl, Pet Food Is a Risky Business for the vegan diet item.  Vegan diets may be more environmentally sustainable, but are they best for a dog or cat’s health?  That question involves assumptions and tradeoffs about health and environmental impact.

The health impact would be easier to address if researchers were studying such questions.  But, as I discussed in my co-authored book about pet food issues, Feed Your Pet Right, remarkably little research is being done on dog and cat diets.  I think there are three reasons for the lack of research:

1. Pet owners do not approve of experimentation on companion animals.
2. The government does not want to bother to invest in research on pet food.
3. No pet food company wants to pay for diet studies that might not help sell pet food.

Personally, I would like to see studies examining the effects of high- and low-end commercial foods on health and sustainability.  Without them, we are left with assumptions and tradeoffs, and personal beliefs about what’s best for our beloved animals.

Two items about pet food this week.  Today: safety.  Tomorrow: environmental sustainability.

I have a long-standing interest in pet food, which I view as an integral—essential—component of our overall food system , not least because pet food uses food components that would otherwise be wasted.  I co-authored a book about pet food issues: Feed Your Pet Right.

If there are problems with the safety of pet food, you can bet those problems will occur in the food supply for humans.  I wrote a book about that too: Pet Food Politics: The Canary in the Coal Mine.

I am not the only one interested in such topics.  Phyllis Entis has written two books crticizing the safety hazards of pet foods.

• TOXIC. From Factory to Food Bowl, Pet Food Is a Risky Business

She keeps me up-to-date on the latest problems that arise.

I don’t know how closely you’re watching the pet food industry these days, but I thought this piece I just posted might interest you: When ‘truths’ collide: Darwin’s, ANSWERS, and the FDA

This was an account of an FDA Advisory and its non-consequences: Do Not Feed Certain Lots of Darwin’s Natural Selections Pet Food Due to Salmonella and Listeria monocytogenes.

The U.S. Food and Drug Administration is cautioning pet owners that FDA samples of five Darwin’s Natural Pet Products raw cat and dog food made by Arrow Reliance, Inc. tested positive for Salmonella and a sixth FDA sample tested positive for Salmonella and Listeria monocytogenes (L. mono)…If you have any of the Darwin’s Natural Selections pet food product listed above, stop feeding the product to your pets and throw it away in a secure container where other animals, including wildlife, cannot access it. Do not donate the food.

The bigger story here, as Phillis Entis explains, is that the FDA did not force the company to recall the products; it asked Darwin to rissue a recall volunarily.

But in this case, the company resisted.  It voluntarily decided not to do the recall.  Pet Food Industry (an essential source of information) tells this story.

In a September 20, 2024, memo from the company to consumers which was sent to Petfood Industry, Darwin’s Natural Pet Products had this to say given the FDA’s public notice regarding the affected lots of cat and dog food.

The memo is worth a look.  It says things like this:

• At Darwin’s, the health and safety of your pets is our absolute top priority, and we take rigorous steps to support their well-being and to foster strong lines of communication with you and our fellow community members.
• It is also very important to know that the FDA has received no consumer complaints regarding any of these lots.
• We find the FDA’s public notice to be wholly unnecessary, and ultimately, based on flawed regulatory decision-making, and we have taken steps to make this position clear to the agency.

Oh.

Food safety lawyer Bill Marler asks: Will the FDA use its Recall Authority to Mandate a Pet Food Recall due to Salmonella and Listeria?   .The FDA has that authority.  It did not use it.

That leaves you on your own to make sure you do not buy Darwin products for your pet.

The FDA provides plenty of information as a basis for you taking responsibility for such things.

Its advisory asks this question: Why is the FDA concerned about Salmonella and L. mono in pet food?

Pet foods contaminated with Salmonella and L. mono are of particular public health importance because they can affect both human and animal health. Pets can get sick from Salmonella and may also be carriers of the bacteria and pass it on to their human companions without appearing to be ill…The Federal Food, Drug, and Cosmetic Act requires that all animal foods, like human foods, be safe to eat, produced under sanitary conditions, contain no harmful substances, and be truthfully labeled. Refrigeration or freezing does not kill Salmonella or L. mono.

It provides  these resources:

• Get the Facts about Salmonella
• Salmonella (Salmonellosis)
• Get the Facts about Listeria
• Listeria (Listeriosis)

Do we need more forceful regulation of pet food?  Of course we do.

I subscribe to Pet Food Industry and greatly admire the superb quality of its reporting.

Here’s an example:

Pet obesity 2023: owners oblivious, vets scared to talk: Pet owners may be largely unaware that there is a problem, especially with their own dogs and cats, despite years of warnings.

Several items in this article got my attention.

A.  It is based on a survey by The Association for Pet Obesity (APOP).  Pet obesity is such a widespread problem that it has induced formation of a society to address it.

B.  Pet owners do not recognize that their pets are overweight.

The survey found only 28% of cat owners and 17% of dog owners to say their pets were overweight.  Instead,  84% of dog owners and 70% of cat owners said their pets’ weights were healthy.

Veterinarians say 59% of dogs and 61% of cats are overweight or obese, and percentages are rising.

C.  Veterinarians are reluctant to discuss obesity with pet owners.

Although the survey found 84% of veterinarians to report encountering “pet owners who appeared embarrassed or angry when told their pet was overweight,” only 4% of owners thought their veterinarian would be uncomfortable discussing the issue.

Comment

None of this should be surprising, as I think about it.  Doctors avoid discussing obesity with human patients (embarrassment, stigma, and lack of time, empathy, or satisfactory treatment approaches).  Obesity has become the “O” word.

An astonishing 75% of U.S. adults are overweight or obese, and children are also getting there.

We, as a society, need to prevent this kind of weight gain for ourselves, our kids, and our pets.

How to do this requires policies, and lots of them, all at once.  Policies require politics.  Politics requires advocacy.

We need all of these, and right away.

Resources

Sunday’s New York Times has an entire section on pets.

Information about my book with Malden Nesheim on pet food issues, Feed Your Pet Right, is here.

I haven’t said anything about pet food in a while, in part because I’m waiting to see what the FDA is planning to do about it, if anything.  The FDA currently regulates pet food the same way it regulates feed for farm animals.  Pet food labels look like feed labels.  They do not have Nutrition Facts or Pet Food Facts labels, making their contents difficult to understand.  There is a push to improve that situation and I .wish it were stronger.

FDA regulation of pet food

The Food and Drug Administration (FDA) regulates pet food similar to that for other animal foods. The Federal Food, Drug, and Cosmetic Act (FD&C Act) requires that all animal foods, like human foods, be safe to eat, produced under sanitary conditions, contain no harmful substances, and be truthfully labeled. In addition, canned pet foods must be processed in conformance with the low acid canned food regulations to ensure the pet food is free of viable microorganisms.

I don’t see much sign that is changing.  Members of Congress introduced the PURR [Pet Food Uniform Regulatory Reform] Act to give the FDA authority over the  labeling and ingredient review process for dog and cat foods, currently up to the states.

As explained by Pet Food Industry,

The Pet Food Institute (PFI) noted in a press statement that the proposed bill language solely impacts pet food label reviews and codifies ingredients and marketing claims in the Association of American Feed Control Officials (AAFCO) Official Publication.

AAFCO sets ingredient definitions, label standards and laboratory standards and everybody uses them.

I wish it would propose Pet Food Facts labeling.

My book with Malden Nesheim, Feed Your Pet Right, has a lot to say about these issues.  It’s still useful for understanding what they are about.  It’s really not a manual for feeding pets (although we did include recipes).  It’s an analysis of the pet food industry, something I still think worth knowing about.

AAFCO, the American Association of Feed Control Officials, says its membership has at last agreed to fix pet food labels so they look more like Nutrition Facts labels.  When this happens, you might possibly be able to understand them.

Here’s what the nutrition information on a pet food label looks like now.

Pet food labels follow the regulations for animal feed, not human food.

This might have made sense when dogs and cats were on their own to hunt or be fed household scraps, but it makes no sense at all now that pets are considered members of the family—fur babies.

The agreed-upon changes have to be incorporated into state regulations, and manufacturers need time to adopt them.  Everybody gets 6 years to do this, although some companies will undoubtedly start using the new rules right away.

The changes will be in four areas of the labels:

1. Nutrition Facts Box – Updated to resemble human-food labeling more closely.  This will be a Pet Nutriton Facts panel.
2. Intended Use Statement – Updated to new location on the lower-third of the front display panel to help consumers easily identify the purpose of the pet food.
3. Ingredient Statement – Updated to clarify the use of consistent terminology and allow parentheticals and common or usual names for vitamins.
4. Handling and Storage Instructions (optional) – Updated and standardized with optional icons for greater consistency.

This is a great step forward.  One reason why I think so is that the new Pet Nutrition Facts label is exactly what Mal Nesheim and I recommended in our book, Feed Your Pet Right.

That book came out in 2010; these rules go into effect in 2029.

It pays to be patient—and to persist!

I’m working on a book chapter on pet food and was interested to hear from Phyllis Entis, author of TAINTED. From Farm Gate to Dinner Plate, Fifty Years of Food Safety Failures, who sent me this.

The study: Isabella Corsato Alvarenga, Amanda N. Dainton & Charles G. Aldrich (2021).  A review: nutrition and process attributes of corn in pet foods, Critical Reviews in Food Science and Nutrition, DOI: 10.1080/10408398.2021.1931020

Background: “Corn is one of the largest cereal crops worldwide and plays an important role in the U.S. economy. The pet food market is growing every year, and although corn is well utilized by dogs, some marketing claims have attributed a negative image to this cereal.”

Purpose:  “the objective of this work was to review the literature regarding corn and its co-products, as well as describe the processing of these ingredients as they pertain to pet foods.”

Findings: “Corn is well digested by both dogs and cats and provides nutrients…In conclusion, the negative perception by some in the pet food market may not be warranted in pet foods using corn and its co-products.”

Conflicted interests: “The authors are with the Department of Grain Science and Industry, Kansas State University, Manhattan, Kansas, USA.”

Funding: “This work was commissioned by the Kansas Corn Commission.”

Comment:  For the record, substantial research supports the ability of dogs and cats to digest and use the nutrients in corn.  This has been documented for a long time.  The purpose of this review is to reassure pet owners that it’s to feed corn-containing products to their dogs and cats.  Corn is the most prevalent ingredient in commercial complete pet foods.   Lots of pet owners believe that grain-free foods are bad for pets and are buying grain-free products.  These must be cutting into sales.  Once again, this is an industry-funded study with predictable results.

Pet food, as I am fond of repeating, is an essential part of the human food supply because it uses the waste from human food production.

Also, whatever is happening with pet food indicates what could well be happening with human food.

That’s why I was fascinated to read this account in Pet Food Industry of finding DNA from endangered sharks in any number of pet food brands.

Researchers identified shark genetic material in cat foods purchased in Singapore, including Fancy Feast, Sheba, Whiskas, Kit Cat and Aixia Yaizu. The scientists suggested that endangered silky sharks and other species ended up in pet foods. However, the study’s authors couldn’t determine the route by which the shark meat made its way into the pet food supply chain. Likewise, they didn’t have easy solutions for how pet food companies could avoid inadvertently allowing endangered sharks into their products.

The evidence comes from a report of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Pet Food Industry further explains:

The silky shark (Carcharhinus falciformis), listed as CITES Appendix II, was the second most frequently encountered species in the pet foods. Silky sharks face tremendous hunting pressure for their fins. The researchers speculated that the presence of the silky sharks may reflect the use of the rest of their carcasses in pet food.

Blue sharks, Prionace glauca, were the most common species in the samples. Blue sharks are not listed in CITES or classified as threatened by the IUCN, but scientists believe it is being overfished and needs regulation.

None of the pet foods’ ingredient decks mentioned sharks. Terms such as “ocean fish,” “white fish” and “white bait” appeared though.

I wrote about the pet food supply chain (particularly as related to melamine contamination) in Pet Food Politics and, with Mal Nesheim, in Feed Your Pet Right.  

The point: If we don’t want to encourage destruction of endangered species, we ought to be checking cans of tuna for people while we are at it.
