What caused the issue?

A production and packaging process breakdown

Second Nature Brands confirmed in its recall notice that the undeclared allergens reached consumers as a result of a temporary breakdown in the company’s production and packaging processes. In practical terms, this means the wrong product was placed into the wrong packaging, or a product formulation change was not reflected in the packaging used for a specific production run. The result was that Keto Crunch Smart Mix pouches with a best-by date of February 12, 2027, contained cashews and pistachios, both classified as tree nuts under the Food Allergen Labeling and Consumer Protection Act (FALCPA), along with cherries, without any of those ingredients appearing on the label.

Why tree nut allergens are particularly serious

Cashews and pistachios are among the most common triggers of severe allergic reactions. Both are classified as tree nuts, one of the nine major food allergens the FDA requires manufacturers to disclose on every product label sold in the United States. Tree nut allergies can produce symptoms ranging from mild itching or hives to full anaphylaxis, a rapid and life-threatening immune response that requires immediate emergency treatment. For consumers who avoid tree nuts specifically to protect themselves, an undeclared cashew or pistachio in a snack mix they trusted to be safe represents a direct and serious health risk.

Cherries, while not classified as a major allergen under FALCPA, can trigger reactions in individuals with sensitivities to stone fruits or salicylates. Their inclusion in this recall reflects Second Nature Brands’ commitment to full transparency about what was present in the affected pouches.

The better-for-you snack category and allergen risk

This recall carries a particular editorial note for the better-for-you snack category. Keto Crunch Smart Mix is positioned as a health-conscious product targeting consumers following ketogenic dietary patterns. Those consumers tend to read labels carefully and purchase products based on specific nutritional and ingredient criteria. When a production breakdown places undisclosed ingredients in a product that a health-conscious shopper has chosen with deliberate care, the breach of trust is compounded. The label is not just a regulatory requirement. For that consumer, it is the foundation of every purchasing decision they make.

Behind the brand

Second Nature Brands is a Madison Heights, Michigan-based snack and treats company with roots going back to 1933, when founder Sue Kar began roasting peanuts at home to sell outside Tiger Stadium in Detroit. What started as a home operation grew into Kar Nut Products Company, which the Nicolay family acquired in the 1960s and expanded into a nationwide trail mix business. In 2021, the company rebranded as Second Nature Brands, consolidating Kar’s Nuts, Second Nature Snacks, and Sanders Chocolates under one platform. Today the company also owns Sahale Snacks, Voortman Bakery, and Brownie Brittle, and operates under the ownership of London-based private equity firm CapVest Partners.

Second Nature Snacks, the brand under which Keto Crunch Smart Mix is sold, positions itself as a natural and non-GMO verified premium snack line for health-conscious consumers. Kar’s Nuts and Second Nature Snacks together rank among the top-selling trail mix brands in the United States. The company produces its products at manufacturing facilities in Madison Heights and Clinton Township, Michigan.

Other relevant recalls

Undeclared tree nut allergens in snack and trail mix products represent a recurring pattern across the food industry, and this recall is the latest example from a nationally distributed brand. In April 2026, We R Nuts recalled Uncle Giuseppe’s Milk Chocolate Bridge Mix after three allergens, including cashews, were found missing from the label of a specialty snack product sold in New York and New Jersey. In March 2026, Favorina Chocolate Ladybugs were recalled at Lidl US stores after hazelnut was found undeclared across ten East Coast states. Earlier this year, Schreiber Foods recalled Einstein Bros Honey Almond Cream Cheese Spread after almonds were missing from cream cheese cups distributed to four states. Gregory’s Foods recalled its Bag Full of Cookies frozen cookie dough after peanut-containing dough was placed into the wrong packaging. And Cal Yee Farm recalled multiple snack products after a routine FDA inspection found six undisclosed allergens across a single product line.

A food safety specialist noted the particular vulnerability that high-inclusion snack mixes present:

“Trail mixes and snack mixes by their nature contain multiple ingredients, many of which are major allergens. When a production process breakdown results in the wrong formulation entering the wrong pouch, the label becomes a mismatch. The risk is real for every tree nut-allergic consumer who bought that pouch because they trusted the label.”

A packaging and production consultant added:

“A single-date recall like this one suggests the issue was isolated to a specific production run. That is actually a sign that the company’s traceability systems are working. The question is always what failed upstream to allow the wrong product to enter the right packaging in the first place.”

Eran Mizrahi, CEO of Source86, said the recall highlights the allergen risks that exist even at established national brands:

“Food safety isn’t just about compliance; it’s about trust. Every recall reminds us how vital it is to maintain transparency, rigorous checks, and supplier accountability. A production breakdown can happen at any scale. What matters is how quickly a company catches it and how completely they respond.”

Ensuring safe eats

The Second Nature Brands recall is a timely reminder that production process breakdowns can introduce undeclared allergens into products from nationally recognized brands. For consumers with tree nut allergies, a trusted better-for-you snack brand is not a guarantee of safety if a specific production run was affected by a packaging error.
