A new FDA recall notice has put Horizon Organic chocolate milk back in focus after a packaging problem was linked to thousands of shelf-stable milk cartons distributed in several western U.S. states.
The recall involves Horizon Organic Shelf Stable 1% Lowfat DHA Omega-3 Chocolate Milk sold in 8-ounce boxes as part of 6-pack packages. The affected cartons may have a faulty packaging seal, a defect that can allow the boxes to swell, leak, or spoil before the printed best-by date.
According to the U.S. Food and Drug Administration, the recall has been classified as a Class II recall. That classification is used when a product may cause temporary or medically reversible health effects, while the likelihood of serious health consequences is considered remote.
Horizon Organic Dairy, LLC initiated the recall, which covers about 63,396 cartons. The action was first announced on March 11, 2026, before later receiving its FDA classification. The company said the problem was tied to a packaging seal issue and added that corrective and preventive measures had been put in place to reduce the chance of the problem happening again.
How to identify the recalled Horizon Organic chocolate milk
Consumers should check the packaging carefully, especially if the product was purchased for school lunches, pantry storage, travel, or childrenâs snacks. The recalled milk can be identified by the following details:
- Brand: Horizon Organic
- Product: Shelf Stable 1% Lowfat DHA Omega-3 Chocolate Milk
- Package: 8 fl. oz boxes sold in 6-packs
- UPC: 742365004322
- Item Number: 136518
- Best By Dates: Aug. 14, 2026 and Aug. 15, 2026
- Estimated Quantity: 63,396 cartons
The recalled cartons were distributed in Arizona, California, Nevada, and Oregon. Shoppers in those states should compare the UPC, item number, and best-by date before using the product.
The main concern is not the chocolate milk formula itself, but the packaging integrity. Shelf-stable milk depends on sealed packaging to keep the product safe without refrigeration before opening. If that seal fails, the milk may spoil even if the carton still appears unopened.
Warning signs may include swollen packaging, leaking edges, unusual smell, off taste, or visible changes in the product. However, consumers should not taste the milk to test whether it is safe. If the product matches the recalled details, it should be thrown away.
Horizon Organic has advised customers to discard the affected cartons, keep proof of purchase, and contact the company at 1-888-494-3020 to ask about possible refund eligibility.
Packaging-related recalls can be easy to overlook because they may not sound as alarming as contamination alerts. Still, dairy products are sensitive to spoilage once packaging protection is compromised. Families that regularly buy boxed milk or long-life dairy products should monitor recent food recall and consumer safety updates closely as more packaging-related incidents continue appearing across the grocery industry.

The recall is also notable because Horizon Organic is a widely recognized dairy brand, and single-serve chocolate milk boxes are often used by parents because they are convenient and do not require refrigeration before opening. That convenience depends heavily on the package seal remaining intact throughout storage and distribution.
The FDAâs Class II designation does not mean every carton will cause illness. It means the agency sees a possible health risk if the affected product is used, but serious outcomes are not expected in most cases. Consumers with children, older adults, pregnant people, or anyone with a weakened immune system should be especially careful with spoiled dairy products.
Retailers in the affected states may remove recalled items from shelves, but consumers should still check products already purchased. A recall can remain relevant long after the announcement date when shelf-stable products have future best-by dates, as is the case with the recalled Horizon Organic cartons dated August 2026.
Anyone who has the recalled Horizon Organic chocolate milk should not drink it, serve it to children, or donate it. The safest step is to dispose of the product and contact Horizon Organic directly with proof of purchase for refund guidance.
