About Mackerel
Mackerel is an oily marine fish added to pet food to supply animal protein and natural EPA and DHA omega-3 fatty acids.
Mackerel is a fatty fish commonly used in pet foods as a high‑quality animal protein and a rich source of omega‑3 fatty acids (EPA and DHA), often added for flavor, palatability and healthy fats. Its omega‑3s support skin and coat condition, immune and joint health in dogs and cats, but owners should be aware of potential heavy‑metal accumulation, food sensitivities, and higher fat or sodium in some preparations, so choose properly processed, deboned sources from reputable suppliers.

Why it's used
As a fatty fish, mackerel concentrates EPA and DHA without needing added fish oil, while its strong aroma also boosts palatability in wet foods and treats. Smaller, shorter-lived species such as Atlantic or Pacific chub mackerel are generally preferred by formulators over large predatory mackerel species.
Common concerns
- Mercury and heavy metals Large predatory mackerel species (such as king or Spanish mackerel) accumulate more mercury and other heavy metals than smaller, shorter-lived mackerel species, and neither AAFCO nor the NRC has set a specific upper limit for mercury in pet food.
- Histamine formation As an oily fish, mackerel can develop histamine (scombrotoxin) if it is not chilled quickly after catch, since the bacterial enzymes that produce histamine work fastest at warmer temperatures and the compound cannot be removed later by cooking or freezing.
- Fish allergy Fish is one of the more commonly reported food allergens in dogs and cats, so mackerel-based diets are sometimes avoided or introduced cautiously in pets with a known fish sensitivity.
Also relevant
Formulators generally favor smaller mackerel species and controlled sourcing partly to limit the contaminant and spoilage concerns described above.
