Merrick Classic Beef Dry Dog Food
Lower PFAS concern for dry kibble in standard pet food bag, but no brand transparency.
Merrick Classic Beef is packaged in a typical kraft-and-polyethylene dry pet food bag, materials not inherently linked to PFAS use. However, Merrick makes no public disclosure about PFAS testing, supplier vetting, or bag composition.

The full breakdown
What it's made of and why it matters
Merrick Classic Beef is packaged in a multi-layer kraft paper and polyethylene (PE) composite bag, standard across the dry pet food industry. The kraft exterior provides structural rigidity and printable surface; the inner PE layer acts as a moisture and oxygen barrier to preserve kibble freshness and prevent rancidity of the beef fat content. Dry kibble formulations present lower migration risk than wet or canned foods because there is no liquid phase to extract chemicals from packaging, and the low moisture environment discourages leaching of additives from the bag material itself.
The brand's record and disclosure
Merrick is owned by Big Heart Pet Brands (a subsidiary of J.M. Smucker Company) and has no major published safety recalls specific to packaging contaminants in recent years. The brand does not publicly disclose PFAS testing, certification, or mitigation strategies for its packaging, making its stance effectively silent on this hazard class. Merrick has faced recalls for ingredient contamination (salmonella in raw frozen products) but not for packaging chemical hazards in dry kibble lines, suggesting either low contamination or limited third-party scrutiny.
How it compares in its category
Dry dog food bags from mainstream brands (Purina, Royal Canin, Iams, Merrick) typically use identical kraft-PE barrier structures; Merrick does not stand out as safer or riskier on material alone. Brands offering explicit PFAS-free or compostable packaging (such as some smaller premium lines) are rare in this category and may carry higher cost. Merrick's ingredient transparency and sourcing claims (e.g., 'grain-free', named meat proteins) are competitive but do not address packaging safety specifically.
If you buy it
Store bags in a cool, dry place away from direct sunlight to prevent polyethylene degradation and any potential accelerated leaching, though this risk is minimal in dry food. Reseal bags tightly after opening using the printed fold-top closure or a clip to maintain freshness and barrier integrity. Discard bags showing visible damage, punctures, or signs of moisture ingress, as compromised barriers can allow oxidation of fat and potential mold growth. No special handling or heating restrictions apply; polyethylene in pet food bags is not designed to contact hot water or be microwaved.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Polyethylene film degradation and microplastic shedding
Long-term storage or exposure to light and heat can cause PE film to become brittle and shed microparticles. In dry kibble, direct contact is indirect (kibble sits on film, not in liquid), so ingestion risk is lower than with wet food, but not zero over years of storage.
Mineral oil and ink migration from printed bag exterior
Kraft paper bags are printed with food-grade inks; FDA regulations restrict ink composition. No recalls or reports of mineral oil or pigment migration into Merrick dry kibble specifically; the PE barrier layer provides intermediate protection.
Rancidity and oxidation of beef fat in kibble
Beef fat is prone to oxidation over time, especially if bag seals are compromised or storage is warm and humid. This is an ingredient quality issue, not a packaging chemical hazard, but poor bag integrity can accelerate it. No specific rancidity recalls for this product line are on record.
Moisture ingress leading to mold or bacterial growth
If kraft-PE seals fail (punctures, manufacturing defects, or improper reseal by consumer), moisture can enter and create an environment for Aspergillus or Salmonella. This is a use and storage issue rather than an inherent material hazard; Merrick has not reported widespread moldy kibble complaints.
Heavy metals in beef source ingredient
Lead, cadmium, and arsenic can bioaccumulate in cattle feed and tissues. Merrick does not publicly disclose heavy metal testing of beef ingredients. No specific recalls for heavy metal contamination in this product are on record, but ingredient sourcing transparency is limited.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
