Investigation Update: Cyclospora Outbreak, July 2026

For Everyone
July 24, 2026

Key points

• CDC, FDA, and public health officials in several states are investigating a multistate outbreak of Cyclospora infections linked to iceberg lettuce in 9 states.
• Do not eat recalled iceberg lettuce from Taylor Farms de Mexico. If you purchased recalled lettuce, throw it out or return it.
• CDC is also investigating other outbreaks and illnesses of cyclosporiasis nationally that are unrelated to this outbreak.

Latest update

Epidemiologic and traceback data continue to show that iceberg lettuce from Taylor Farms de Mexico was contaminated with Cyclospora and has made people sick.

Epidemiologic data

Since the last update on July 18, 2026, additional confirmed cases of cyclosporiasis related to this multistate outbreak have been reported, and the total case count associated with this multistate outbreak is now 1,947. This includes the addition of 4 states: Illinois, Kansas, Oklahoma, and Pennsylvania.

State and local public health officials are interviewing people about the foods they ate in the two weeks before they got sick. A total of 1,947people infected with Cyclospora and reporting exposure to Taco Bell have been reported by 9 states. Illnesses linked to this outbreak began on June 22 and onset dates have continued through July 20, 2026. There have been at least 98 hospitalizations, and no deaths have been reported. Of note, this number includes sick people who have traveled to states involved in the outbreak in the two weeks before their illness began and ate at Taco Bell.

The true number of sick people in this multistate outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because some people recover without medical care and are not tested for Cyclospora. In addition, recent illnesses may not yet be reported because it can take as long as 6 weeks to determine if a sick person is part of a Cyclospora outbreak. States in this outbreak may report different illness counts on their websites as they may also include probable illnesses. CDC and FDA are only reporting laboratory confirmed cases.

Surveillance of Cyclosporiasis

For Public Health
July 28, 2026

Key points

• Since May 1, 2026, CDC has received reports of 6,707 laboratory-confirmed domestic cases of cyclosporiasis.
• CDC is aware of more than 11,500 additional cases that are not laboratory confirmed or require further investigation and analysis, such as ruling out international travel. Many of the additional cases have been reported by Michigan and Ohio.
• CDC's surveillance updates do not include probable cases. State data may include probable and confirmed cases, resulting in higher case counts than what CDC reports. CDC is working closely with states to update numbers as additional cases are confirmed.
• CDC is publishing weekly surveillance data updates in 2026 due to the increase in cases in multiple states compared to the same period in 2025.
• CDC is investigating multiple clusters of Cyclospora cases, including one multistate outbreak affecting 9 states linked to iceberg lettuce.

Recall alert

On July 17, 2026, Taylor Farms recalled iceberg lettuce sourced from central Mexico. The recall includes iceberg lettuce sold at retail stores and served in restaurants. It also includes other recalled products distributed to food service customers. A list of products is included in the recall notice.

​These people became sick after eating food in the United States and did not report any international travel during the 14 days before they got sick.

They ranged in age from 1 to 98 years, with a median age of 44, and 56% were female. The median illness onset date was July 2, 2026 (range from May 1 to July 25).

These data include the cases reported in the large multistate outbreak in 9 states tied to iceberg lettuce. Multiple jurisdictions have reported an increase of cases compared to the same period in 2025. We estimate a 6-week reporting lag between illness onset and case reporting to CDC, so we anticipate that case counts will continue to rise as data are received.

CDC teams are working diligently to collect, analyze, and provide data at the national level. State health departments may have more timely information about the situation in their jurisdictions.

Notice

CDC is aware of more than 11,500 additional cases of cyclosporiasis that are not laboratory confirmed or require further investigation and analysis. Many of the additional cases have been reported by Michigan and Ohio. CDC is working closely with states to update surveillance data as additional cases are confirmed.

Case locations

This map shows the resident states of the 6,707 people with laboratory-confirmed domestically acquired cyclosporiasis since May 1, 2026. Potential Cyclospora infections are typically investigated by the state or local health department where people live, even if they were exposed to the parasite in another state. Cyclosporiasis cases may not be limited to these states with known cases. The true number of people sick with cyclosporiasis was likely higher than the number reported. This is because some people recover without medical care and are not tested for Cyclospora.
