Check your pantry right now. If you have bags of Zapp's or Dirty brand potato chips sitting around, you might want to double-check the labels before your next snack craving hits. What started as a cautious, quiet move by the manufacturer has turned into a major health warning.
The Food and Drug Administration just upgraded the ongoing recall of nearly 685,000 bags of popular potato chips to a Class I designation. That's the most severe warning level the agency uses. It means the government believes there's a legitimate, reasonable probability that eating these chips could lead to serious health problems or, in extreme cases, death.
If you bought these brands recently, here's exactly what's going on, which flavors are contaminated, and what you need to do next.
Inside the Salmonella Risk
The issue traces back to the seasoning. Utz Quality Foods, the parent company behind both the Zapp's and Dirty brands, actually started pulling these bags back in April and May. They did it because one of their third-party seasoning suppliers used a dry milk powder sourced from California Dairies, Inc.
California Dairies had flagged that specific milk powder for potential Salmonella contamination. Interestingly, subsequent testing on the chip seasoning itself actually came back negative for the bacteria. Utz moved forward with the recall anyway out of an abundance of caution, but the FDA's recent upgrade to a Class I risk level emphasizes that the agency isn't taking any chances with the supply chain trail.
The fallout isn't even contained to the chip aisle. This same problematic milk powder batch triggered recalls for other major brands, including several of Ghirardelli's powdered beverage, hot cocoa, and frappe mixes.
To date, Utz hasn't received any official reports of illness tied to the chips. But with nearly 685,000 bags floating around 35 different states, the risk window remains wide open.
The Recalled Flavors and Batch Codes
This isn't a blanket recall on every single bag of Zapp's or Dirty chips on the market. It impacts specific sizes and flavors, mostly with "Best By" dates stretching across July and August 2026.
The primary products you need to look out for include:
- Zapp’s Bayou Blackened Ranch: Found in 1.5-ounce, 2.5-ounce, and 8-ounce bags. Look for Best By dates of July 27, or August 3, 10, 17, 24, and 31.
- Zapp’s Big Cheezy: Affected in 1.5-ounce, 2.5-ounce, and 8-ounce sizes, with Best By dates running through August 31.
- Zapp’s Salt and Vinegar: Specifically the 1.5-ounce bags included in 60-count variety packs, with Best By dates of August 3 and 10.
- Dirty Brand Salt and Vinegar: Found in 1.5-ounce and 2-ounce bags. Check for UPCs 83791520148, 26030070101, or 26036070102.
- Dirty Brand Maui Onion: Impacting the 2-ounce bags with a Best By date of August 8 (UPC 26052070162).
- Dirty Brand Sour Cream and Onion: Found in 2-ounce bags with an August 31 expiration date.
Distribution hit a massive footprint across the United States. If you live in New Jersey, New York, Pennsylvania, Connecticut, Texas, Florida, or dozens of other states where these brands dominate convenience stores, you're in the distribution zone.
What Salmonella Exposure Actually Means
It's easy to shrug off a food recall notice, but Salmonella isn't something to ignore. For a healthy adult, it usually means a miserable few days of fever, severe stomach cramping, nausea, vomiting, and diarrhea.
But the stakes are much higher for young kids, the elderly, or anyone with a compromised immune system. In those vulnerable groups, the infection can make its way into the bloodstream. Once there, it can cause severe, life-threatening complications like arterial infections, endocarditis, or severe arthritis. Symptoms generally pop up anywhere from six hours to six days after eating the contaminated food.
What You Should Do Now
Don't panic, but don't eat the chips.
Go through your kitchen and look for the specific flavors and bag sizes listed above. If you find a match, throw the bag directly into the trash. Make sure it's sealed or disposed of safely so pets can't get into it. You can also return the product to the store where you bought it for a full refund.
If you have questions about specific batch numbers or want to verify a bag you own, you can call Utz Quality Foods directly at 877-423-0149 to speak with their customer service team.
