If iceberg lettuce is in your refrigerator, take a minute to check it before serving salad, sandwiches or tacos this week. The Food and Drug Administration says consumers should not eat recalled iceberg lettuce from Taylor Farms de Mexico while a Cyclospora outbreak investigation continues.

The useful question is not whether every salad is unsafe. It is whether the lettuce you bought, received from food service, or ordered at a restaurant could match the recalled products or supplier. FDA says the recall began on July 17, 2026, and covers iceberg lettuce sourced from central Mexico.

The recall includes Marketside-brand Iceberg Salad in 12-ounce and 24-ounce bags with Best if Used By dates from July 18, 2026, to August 3, 2026, and Marketside Shredded Lettuce in 8-ounce and 16-ounce bags with dates from July 18, 2026, to August 3, 2026. FDA says other recalled products went to food-service customers, so restaurants and institutions may need to check the company list rather than a retail bag.

Do this first

Check the bag, box label or purchase record for iceberg lettuce, shredded lettuce, chopped lettuce, salad mix, blend lett/rom or Marketside iceberg products. If it matches the recalled product, do not taste it to see if it seems fine. Throw it away or follow the seller's refund instructions.

If the lettuce came from a restaurant, ask whether the iceberg lettuce came from Taylor Farms de Mexico or from the recalled supply. FDA says any Taco Bell locations that received recalled iceberg lettuce should not serve it, and Taco Bell has said it stopped using lettuce from that supplier as of July 17, 2026.

Clean what it touched

After removing recalled lettuce, clean and sanitize refrigerator drawers, bowls, cutting boards, counters and containers that touched it. Keep the cleanup practical: wash visible debris away first, then use an appropriate kitchen sanitizer or dishwasher cycle for items that can handle it. Wash your hands after handling the recalled food or trash.

Know the symptoms

Cyclospora can cause diarrhea, frequent bowel movements, loss of appetite, weight loss, stomach cramps, bloating, gas, nausea and fatigue. FDA says vomiting, body aches, headache and fever can also occur, and symptoms may appear to improve and then return.

Contact a health care provider if you have symptoms, especially if you ate shredded iceberg lettuce in the two weeks before you became sick. Seek care promptly for dehydration signs, severe symptoms, prolonged diarrhea, high-risk medical conditions or immune-system concerns.

What changed this week

The investigation is still moving. FDA said on July 19, 2026, that a reported positive lettuce sample was later treated as a false positive after re-review. That does not end the advisory: FDA says traceback and outbreak data continue to focus on shredded iceberg lettuce from Taylor Farms de Mexico, and AP reported that federal officials remain focused on that supplier despite the test correction.

The safest move is narrow, not panicked. Check the product details, avoid recalled lettuce, ask restaurants about the source when it matters, clean contact surfaces and watch for symptoms if you may have eaten the affected lettuce.
