Is Your Pet Eating This Toxic Dog Food?

As pet owners, we meticulously choose the best foods for our furry friends, focusing on nutritional value and flavor. But, have we ever considered the packaging of these foods as a potential health hazard? A recent startling revelation has surfaced: most US pet food packaging contains PFAS, or ‘forever chemicals’, known for their persistence in the environment and potential health risks. This article delves into the findings of a study conducted by the Environmental Working Group (EWG), revealing the alarming presence of PFAS in pet food packaging. Not just a concern for our beloved cats and dogs, this issue also poses broader environmental and health implications. As we explore the depths of this issue, let’s understand what PFAS are, how they impact our pets’ health, and what actions we can take as responsible pet owners.

Understanding PFAS: The ‘Forever Chemicals’

PFAS: A Chemical Conundrum

Per- and poly-fluoroalkyl substances, commonly known as PFAS, are a large family of synthetic chemicals that have found their way into numerous consumer products due to their unique properties. These chemicals, often referred to as ‘forever chemicals’, possess an almost indestructible molecular structure that prevents them from breaking down naturally in the environment or in biological systems. This persistent nature is what earned them their ominous nickname.

The Pervasive Use of PFAS

PFAS are valued in the manufacturing world for their ability to resist heat, oil, stains, grease, and water. This makes them ideal for a variety of applications, from non-stick cookware and waterproof clothing to stain-resistant fabrics and fire-fighting foams. Their widespread use, however, comes at a cost. The very properties that make PFAS so useful also make them a persistent environmental contaminant.

Health Concerns Linked to PFAS

Over the years, research has increasingly highlighted the potential health risks associated with PFAS exposure. These chemicals have been linked to a range of health issues, including cancer, liver damage, thyroid disease, decreased fertility, high cholesterol, and developmental issues in children. PFAS can accumulate in the body over time, leading to higher risks of adverse health effects.

Why Should Pet Owners Be Concerned?

For pet owners, the presence of PFAS in pet food packaging is particularly troubling. Pets, much like humans, can accumulate PFAS in their bodies, potentially leading to similar health risks. Given that pets often have shorter lifespans and smaller body sizes compared to humans, their susceptibility to the harmful effects of these chemicals could be even more pronounced.

The Study Findings: Alarming Levels of PFAS in Pet Food Packaging

The recent research by the Environmental Working Group (EWG) has shed new light on the presence of PFAS in pet food packaging, offering detailed insights that are both concerning and informative. This section integrates these specific findings into our earlier discussion on PFAS, highlighting their impact on pet health and household safety.

Startling Statistics from Popular Pet Food Brands

The EWG’s study tested 11 bags of pet food from seven well-known brands found in major retailers like Walmart. The results were alarming: all tested brands contained PFAS, substances linked to serious health concerns such as cancer, harm to fetal development, and reduced vaccine effectiveness in humans.

Breakdown of the Findings: Specific Brands and Concentrations


The Meow Mix Tender Centers Salmon & Chicken Flavors Dry Cat Food showed one of the highest concentrations of total fluorine, over 600 parts per million (ppm). Purina Cat Chow Complete Chicken followed with just over 310 ppm. Other brands like Blue Buffalo, Iams, and Rachael Ray Nutrish had under 100 ppm.


Kibbles n’ Bits Bacon and Steak flavor registered nearly 600 ppm of total fluorine. Blue Buffalo’s Life Protection Formula Puppy Chicken and Brown Rice Recipe was found to have over 150 ppm. Other dog foods from Purina, Iams, and Pedigree showed much lower amounts.
The Specific PFAS Identified

Further analysis revealed individual PFAS compounds in some of the pet food bags, including PFBA, PFPeA, PFHxA, PFHpA, x62FTCA, x62diPAP, and PFPrA. The highest concentration of total PFAS was found in Purina Cat Chow Complete Chicken (245 parts per billion, or ppb), with Kibbles n’ Bits following at almost 15 ppb.

PFAS: A Ubiquitous Threat

The presence of PFAS in almost every American’s blood and their detection in pets underline the widespread nature of these chemicals. They are found in everyday items, shedding PFAS-laced dust that contaminates households and pollutes air and water.

Accelerated Health Risks for Pets

Due to pets’ compressed life spans, which mature and age much faster than humans, their health problems from PFAS exposure develop more rapidly. This factor heightens the urgency of addressing PFAS contamination in pet products.

The Need for Regulatory and Industrial Action

Despite the suggestion of PFAS in pet food bags, direct migration of these chemicals into the pet food itself has not been conclusively determined. However, the potential risk remains a significant concern. The Biden administration has taken steps to address PFAS pollution, but more action is needed, particularly from the FDA, to regulate PFAS in food-related products.

A Call for Comprehensive Measures

This detailed analysis underscores the need for strong state and federal actions to eliminate PFAS pollution sources and end unnecessary uses of PFAS in everyday products, including pet food packaging. It’s imperative for pet food manufacturers and regulatory agencies to take responsibility and act decisively to protect both pets and their owners from the dangers of PFAS.

Health Implications for Pets: The Invisible Threat to Our Furry Friends

Pets are integral members of our families, and their health is a top priority for pet owners. The presence of PFAS in pet food packaging poses an invisible threat to their well-being. Understanding the potential health implications of these chemicals is crucial for responsible pet care.

How PFAS Affects Pets

Similar to humans, pets can accumulate PFAS in their bodies over time. The primary route of exposure is through ingestion, which can occur when PFAS leaches from the packaging into the pet food. Once ingested, these chemicals can persist and accumulate in the pet’s body, potentially leading to various health issues.

Potential Health Risks

The range of health problems associated with PFAS exposure in pets mirrors those in humans, but the risks may be magnified due to pets’ smaller body sizes and different metabolism rates. Potential health effects include:

  • Cancer: Exposure to certain PFAS compounds has been linked to an increased risk of cancer in animals.
  • Liver and Kidney Damage: PFAS can accumulate in these organs, potentially leading to damage and affecting their function.
  • Immune System Disruption: Some studies suggest that PFAS exposure can weaken the immune system, making pets more susceptible to infections.
  • Developmental and Reproductive Issues: Younger animals and those in reproductive stages may be particularly vulnerable to the effects of PFAS.

A Cumulative Concern

It’s important to recognize that the risk associated with PFAS is not only about the levels found in individual products but also about the cumulative exposure over time. Even pet foods with relatively lower levels of PFAS can contribute to the overall body burden of these chemicals in pets.

The Need for More Research

While the current understanding of PFAS toxicity is based on human studies and laboratory animal models, there is a growing need for more pet-specific research. This research could help to better understand the unique risks these chemicals pose to different types of pets and breeds.

Beyond the Bowl: PFAS in the Home Environment

The Wider Reach of ‘Forever Chemicals’

The issue of PFAS contamination extends far beyond pet food packaging. These chemicals have a notorious reputation for their ability to spread and persist in the environment, leading to broader concerns for both pet and human health, as well as environmental sustainability.

PFAS in Our Homes

One of the more insidious aspects of PFAS is their ability to migrate from products like pet food bags into our homes. These chemicals can detach from packaging and accumulate in household dust, air, and surfaces. This means that the potential exposure to PFAS isn’t limited to pets; family members, particularly young children who are prone to putting things in their mouths, can also be at risk.

Environmental Accumulation and Impact

PFAS are not just a household concern; they are a global environmental issue. These chemicals can leach into soil and water systems, persisting for years, if not decades. This widespread contamination affects wildlife and disrupts ecosystems. PFAS have been found in water bodies, impacting aquatic life, and have even been detected in remote areas, indicating their far-reaching impact.

The Vicious Cycle of Contamination

The persistent nature of PFAS creates a vicious cycle of contamination. Once released into the environment, these chemicals can re-enter the food chain, accumulating in animals and plants, and potentially finding their way back onto our plates and into our pets’ food bowls. This cycle of contamination raises significant concerns about the long-term sustainability of our environment and the health of all living beings.

Taking Action at Home

While the broader issue of PFAS contamination requires systemic change and regulatory action, there are steps individuals can take to reduce exposure in their homes:

  • Choosing PFAS-Free Products: Opting for pet food brands that are committed to PFAS-free packaging.
  • Regular Cleaning: Reducing household dust through frequent cleaning can help minimize the accumulation of PFAS in the home.
  • Staying Informed: Keeping abreast of research and regulations related to PFAS can empower consumers to make safer choices.

Regulatory Inaction and the Need for Change

Navigating the Regulatory Landscape

Despite mounting evidence of the dangers posed by PFAS, there remains a significant gap in regulatory actions to address this issue. This gap is particularly evident in the realm of pet food packaging, where PFAS continue to be used without stringent oversight.

The Current State of PFAS Regulation

Currently, there is no comprehensive legal framework in the United States specifically targeting PFAS in pet food packaging. This lack of regulation means that pet food manufacturers are not required to disclose or limit the use of PFAS in their products. Consequently, pet owners are often left in the dark about the potential risks associated with the pet food they purchase.

The Role of the FDA and Legislative Efforts

The Food and Drug Administration (FDA) plays a crucial role in ensuring the safety of pet food. However, to date, the FDA has not taken significant steps to ban or restrict the use of PFAS in food packaging, including pet food. Legislative efforts to address this issue have been introduced but have yet to gain the necessary momentum and support to become law.

The Need for Stronger Actions

The situation calls for stronger state and federal actions to eliminate sources of PFAS pollution and to end the unnecessary use of PFAS in products, including pet food packaging. Public health advocates argue that decisive action is necessary to protect not just pets, but also the wider environment and public health.

The Power of Public Pressure

Public pressure can be a powerful force in driving regulatory change. Consumer awareness and advocacy can push for stricter regulations and encourage manufacturers to adopt safer alternatives. As consumers become more informed about the risks of PFAS, they can demand transparency and safer practices from pet food companies.

Towards a PFAS-Free Future

The journey towards a PFAS-free future requires concerted efforts from regulators, manufacturers, consumers, and advocacy groups. By working together to raise awareness, advocate for change, and support safer alternatives, we can create a healthier and more sustainable environment for our pets and ourselves.

Tackling the PFAS Challenge: A Call to Action for Pet Owners and Society

The insights from the Environmental Working Group’s study, detailing the alarming presence of PFAS in popular pet food brands, serve as a critical call to action. This conclusion revisits the key points of our discussion and emphasizes the steps we must take as responsible pet owners and conscientious members of society.

Understanding the Gravity of the Situation

The ubiquity of PFAS in pet food packaging is more than just a concern for pet health; it’s a symptom of a larger environmental and public health issue. The detailed statistics from the EWG study underscore the widespread nature of this contamination and its potential to affect not only our pets but also our households and the environment.

Our Role as Informed Consumers

As pet owners, our responsibility extends beyond the immediate care of our animals. We must become informed consumers, and vigilant about the products we choose for our pets. This means seeking out brands committed to PFAS-free packaging and advocating for transparency in product labeling.

Advocacy for Change

The fight against PFAS is not one we can wage alone. It requires collective action and pressure on pet food manufacturers, regulatory bodies, and lawmakers. We need to support initiatives that aim to regulate and eventually eliminate PFAS from consumer products, including pet food packaging.

The Power of Collective Voices

The EWG study serves as a reminder that our voices can make a difference. By raising awareness about the dangers of PFAS and demanding safer alternatives, we can drive change in industry practices and regulatory standards. This collective effort can lead to a healthier future for our pets, ourselves, and the planet.

Embracing a Holistic Approach

Addressing the PFAS issue goes beyond just choosing the right pet food; it’s about adopting a holistic approach to our lifestyle choices. From the cookware we use to the cosmetics we apply, every decision counts in reducing our overall exposure to these harmful chemicals.
