Second Nature Keto Crunch Recall Issued Over Undeclared Nuts and Cherries

A recall was announced on May 5, 2026, for Second Nature Keto Crunch Smart Mix after the product was found to potentially contain undeclared cashews, pistachios, and cherries. These ingredients are not listed on the product label, creating a serious health risk for anyone with allergies or sensitivities to tree nuts or cherries.

According to the recall notice, the affected product is sold under the Second Nature brand and is marketed as a keto-friendly snack mix. The specific product is called Keto Crunch Smart Mix. The recall was triggered after it was discovered that the mix may include cashews, pistachios, and cherries that are not declared on the ingredient list.

What is being recalled?

The recall covers Second Nature Keto Crunch Smart Mix. No lot numbers, UPC codes, or sell-by dates were provided in the initial announcement. The company has not yet detailed the specific distribution channels or the number of units affected. The recall notice advises consumers to check their pantries for any bags of this product and to discard them or return them to the place of purchase for a refund.

Why this matters

Undeclared allergens are one of the most common reasons for food recalls in the United States. The Food and Drug Administration (FDA) classifies undeclared allergens as a Class I hazard when there is a reasonable probability that consuming the product could cause serious adverse health consequences or death. Cashews and pistachios are tree nuts, which are among the major food allergens identified by the FDA. For individuals with tree nut allergies, even trace amounts can trigger severe reactions, including anaphylaxis.

Cherries, while not among the top nine allergens, can still cause reactions in some people, particularly those with oral allergy syndrome or fruit allergies. The combination of undeclared tree nuts and cherries in a product labeled as a smart mix means that anyone relying on the ingredient list to make safe choices could be at risk.

The recall applies to a product specifically marketed for the keto diet. Keto products often appeal to people who are managing diabetes, weight loss, or other health conditions. Some consumers with dietary restrictions may have purchased this snack mix trusting that the label accurately represented the ingredients. Finding undeclared allergens in a health-focused product is especially concerning because it suggests a gap in the manufacturer's labeling or quality control processes.

How recalls unfold

When a company discovers that a product may contain an undeclared allergen, it must act quickly. The FDA expects companies to issue a recall and notify both retailers and the public. The company behind Second Nature Keto Crunch has not yet released a statement explaining how the undeclared ingredients entered the product or whether it relates to a supplier issue, a cross-contact event during production, or an error in labeling.

In typical allergen recall cases, the FDA uses social media, press releases, and its enforcement report database to alert consumers. Retailers are asked to remove the product from shelves and post recall notices. Consumers who have bought the product are advised to check the packaging and contact the company for a refund. Because the recall notice did not include lot numbers or expiration dates, it is possible that the affected product was distributed widely under the same retail packaging, making it hard for consumers to distinguish safe bags from unsafe ones without specific codes.

A pattern of allergen-related recalls

Undeclared allergen recalls happen more often than most consumers realize. Tree nuts are a frequent offender. According to FDA recall data, undeclared tree nuts consistently rank among the top causes of food recalls in the United States. In 2025 alone, dozens of products were pulled from shelves for containing undeclared almonds, walnuts, cashews, or pistachios. The reasons vary: mislabeling, cross-contact in shared processing facilities, or supplier substitutions not communicated to the manufacturer.

The Second Nature Keto Crunch recall fits this pattern. A keto snack mix that was presumably designed to be low-carb and nut-friendly — tree nuts are often used in keto products because they are high in fat and low in carbohydrates — now poses a threat to the very customers who might buy it. The presence of cherries is less typical for keto snacks, as dried fruit often contains added sugars that can raise carbohydrate counts.

What consumers should do

If you have purchased Second Nature Keto Crunch Smart Mix, do not eat it. Check the packaging for any indication that it is the recalled product. Since the recall notice did not provide lot-specific information, the safest approach is to assume any bag of this product is affected until the company issues clarified details. You can return the product to the store where you bought it for a full refund. You may also contact the company directly for further instructions.

Consumers with tree nut allergies or cherry allergies should be especially vigilant. If you or someone in your household has a known allergy to cashews, pistachios, or cherries, dispose of the product immediately. Symptoms of an allergic reaction can include hives, swelling, difficulty breathing, nausea, vomiting, and dizziness. If you experience any of these symptoms after eating the product, seek medical attention right away.

The bigger picture for keto products

The recall also raises questions about quality assurance in the keto food space. The ketogenic diet has grown from a niche medical diet to a mainstream eating pattern. Many companies have launched products competing for that market. The products are often marketed as being carefully formulated for people following strict macronutrient targets. When a product labeled as a smart mix contains ingredients that are not listed, it erodes trust in the entire category.

Second Nature is a brand that markets its products as whole-food-based and label-transparent. This recall undercuts that promise. It also puts pressure on the company to explain how the mistake happened and what steps it will take to prevent a recurrence.

What comes next

The recall is active as of May 5, 2026. The company has not announced how long the recall will last or what investigation it is conducting. It is possible that the recall will expand as investigators trace the source of the undeclared ingredients. Consumers should monitor the FDA website and Second Nature’s own recall page for updated information, including lot numbers and UPC codes, which are likely to be published in a follow-up notice.

Until then, the simplest advice is to avoid Second Nature Keto Crunch Smart Mix entirely. Check your pantry, toss any bags you find, and get a refund. For a product that was supposed to be a safe, convenient snack, the presence of hidden allergens is a serious failure. The recall is a reminder that even products marketed as health-conscious require scrutiny, and that labels are only as reliable as the quality controls behind them.
