Updated August 28, 2026: According to Michigan outbreak data, the state now reports 14,510 cyclosporiasis cases, including 356 people who said they were hospitalized. The Michigan Department of Health & Human Services (MDHHS) has also identified two deaths associated with the outbreak.

A defined subset of Michigan illnesses is part of a 20-state federal Cyclospora outbreak linked to recalled Taylor Farms de Mexico shredded iceberg lettuce. CDC and FDA now report 11,458 illnesses and 495 hospitalizations in that outbreak. Federal investigators include people exposed to the lettuce when it was served or purchased at various locations, including people who previously reported eating at Taco Bell.
Michigan’s outbreak is broader than the federally defined lettuce-linked outbreak. MDHHS says lettuce or salad greens may be one source, but investigators have not ruled out other foods. No single produce item, grower or supplier has been identified as the source of every Michigan case.
Michigan residents do not need to avoid all lettuce or salad greens. MDHHS says people may resume routine guidance for eating lettuce and salad greens because new Cyclospora case reports and related emergency department visits are declining. The recalled Taylor Farms lettuce is past its best-by dates and should no longer be in stores or restaurants.

MDHHS cautions that two apparent jumps in the reporting curve partly reflect delayed laboratory reporting rather than sudden increases in new illnesses. The July 19 reporting week includes about 475 cases that had not previously been reported to MDHHS, and the August 2 reporting week includes about 473 delayed reports.
Some Michigan Cases are Part of a 20-State Lettuce Outbreak
Some, but not all, Michigan Cyclospora illnesses are part of a 20-state multistate outbreak linked by federal investigators to recalled shredded iceberg lettuce from Taylor Farms de Mexico. CDC and FDA report 11,458 illnesses in this defined outbreak, including at least 495 hospitalizations and two deaths in Michigan. Illnesses began as early as June 14 and continued through August 11, 2026.
The recalled shredded iceberg lettuce was served or sold through multiple restaurant, retail and foodservice settings. Some people included in the outbreak had previously reported eating at Taco Bell, but Taco Bell is only one documented exposure setting.
The multistate lettuce-linked outbreak does not account for every Cyclospora illness reported in Michigan. Michigan is investigating a much broader statewide increase, and no single food, grower or supplier has been identified as the source of all Michigan cases. CDC is also tracking other Cyclospora outbreaks and illnesses that are separate from this defined multistate outbreak.

Michigan Cyclospora Outbreak Quick Facts
- Michigan cases: According to MDHHS outbreak data, 14,510 illnesses were reported as of August 27, 2026.
- Michigan hospitalizations: Of the reported Michigan cases, 356 people indicated they had been hospitalized as of August 27.
- Michigan deaths: Two deaths have been reported in Michigan. MDHHS says both people became ill before Taylor Farms de Mexico recalled iceberg lettuce on July 17.
- Michigan outbreak source: Not all Michigan cases have been linked to one source. MDHHS says lettuce or salad greens remain a possible source, but other foods have not been ruled out. The state has not identified one food, grower or supplier that explains every Michigan case.
- Lettuce-linked outbreak: CDC and FDA report 11,458 illnesses in 20 states linked to recalled Taylor Farms de Mexico iceberg lettuce. The outbreak includes 495 hospitalizations and two deaths in Michigan. These cases are only part of the larger number of Cyclospora illnesses reported in Michigan.
- U.S. Cyclospora cases: CDC surveillance includes 17,180 laboratory-confirmed cases acquired in the United States since May 1, including 922 hospitalizations and two deaths. CDC is also aware of at least 11,844 additional cases that are not laboratory confirmed or require more investigation.
- Other Cyclospora outbreaks: CDC and FDA are investigating at least six additional Cyclospora clusters with no confirmed source. FDA’s active investigations include three unidentified-source outbreaks with 203 illnesses (Reference #1392), 28 illnesses (Reference #1385), and 22 illnesses (Reference #1398)
- Iceberg lettuce recall: Taylor Farms de Mexico recalled shredded iceberg lettuce linked to a multistate Cyclospora outbreak that includes Michigan illnesses. The recall explains only part of Michigan’s outbreak, and MDHHS is still investigating other possible sources. FDA says the recalled lettuce should no longer be available for sale.
- Michigan salad guidance: As of an August 6 update, MDHHS no longer recommends that residents avoid all bagged salad mixes. People may return to normal produce-safety practices but should still avoid recalled lettuce.
North Carolina is also reporting elevated cyclosporiasis activity, but NCDHHS says its 940-case increase does not currently appear connected to this outbreak. Parsley, cilantro and lettuce are recurring in North Carolina interviews, with no confirmed source.
Michigan Interviews Show Exposure Was Not Limited to Restaurants
MDHHS reported in a July 24 update that health officials interviewed more than 2,900 people affected by the Michigan outbreak. Many did not report eating lettuce at a chain restaurant or another food establishment, but lettuce still appeared frequently in food questionnaires from people who had not reported restaurant or fast-food exposure.
MDHHS said that pattern was consistent with contaminated produce being distributed through multiple channels, including grocery stores, restaurants and fast-food chains.
Federal investigators have since linked a portion of Michigan illnesses to recalled Taylor Farms de Mexico iceberg lettuce that was distributed through multiple restaurant, retail and food-service settings. However, MDHHS has not identified Taylor Farms lettuce, or any other single food, grower or supplier, as the source of every Michigan case.
People diagnosed with cyclosporiasis should provide health officials with as much detail as possible about what they ate during the 14 days before symptoms began. That can include lettuce and salads purchased at grocery stores, meals from restaurants or fast-food locations, catered or workplace food and delivery orders.
Details such as restaurant locations, grocery stores, brands, purchase dates and receipts can also be important when a Cyclospora lawyer evaluates a possible exposure.
Taylor Farms Lettuce Recall
FDA says recalled Taylor Fresh Foods iceberg lettuce distributed to foodservice customers from June 29 through July 16 was confirmed in 31 states: Alabama, Arkansas, Connecticut, Florida, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maine, Maryland, Michigan, Missouri, Mississippi, North Carolina, Nebraska, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Wisconsin and West Virginia. FDA says recalled product may also have reached California, the District of Columbia, Delaware, North Dakota, Puerto Rico, Rhode Island, South Dakota, Vermont and Washington.
The recalled products are past their best-by dates and FDA says they should no longer be available in stores or restaurants. FDA has initiated an onsite inspection and sampling at Taylor Farms de Mexico and says it remains confident that recalled lettuce related to this specific outbreak is off the market.
Walmart Marketside Lettuce Recall
The recall includes Marketside bagged lettuce sold at select Walmart stores in Alabama, Arkansas, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Missouri, Mississippi, Oklahoma, Tennessee, Texas, Virginia, and West Virginia:
- Marketside Iceberg Salad, 12-ounce and 24-ounce bags, with Best If Used By dates from July 18 through August 3, 2026.
- Marketside Shredded Lettuce, 8-ounce and 16-ounce bags, with Best If Used By dates from July 18 through August 3, 2026.
Consumers should not eat recalled lettuce. The complete FDA recall notice lists additional foodservice products, lot codes, use-by dates, and disposal instructions.
Previous Outbreaks Linked to Taylor Farms Produce
Taylor Farms is based in Salinas, CA, and operates multiple facilities in the U.S. and Mexico. Locations include: Arizona, California, Colorado, Florida, Illinois, Maryland, New Jersey, Tennessee, Texas, and Mexico. This is the fourth major multistate food poisoning outbreak linked to Taylor Farms produce since 2013.
2024 Fatal McDonald’s E. coli Outbreak

In 2024, a fatal E. coli outbreak linked to slivered onions on McDonald’s Quarter Pounder hamburgers caused 104 illnesses and one death. Thirty-four people were hospitalized, four of them with hemolytic uremic syndrome (HUS), a life-threatening complication of E. coli infections that causes kidney failure.
Taylor Farms, a McDonald’s supplier, issued a recall for onions produced at its Colorado facility on October 24, 2024. FDA inspectors found multiple food safety violations at the plant where the onions were produced.
2015 Costco Chicken Salad E. coli Outbreak
In 2015, an E. coli outbreak linked to Costco chicken salad sickened 19 people in seven states. Five people were hospitalized, two of them with HUS.
The Montana Public Health Laboratory tested a sample of celery and onion diced blend produced by Taylor Farms Pacific, Inc., and collected from a Costco store in Montana, and the results indicated the presence of E. coli O157:H7. The product was used to make the Costco rotisserie chicken salad. Further laboratory analysis by the FDA was unable to confirm the presence of E. coli O157:H7 in the sample of celery and onion diced blend. But on November 26, 2015, Taylor Farms Pacific, Inc., recalled the celery and onion diced blend for possible E. coli O157:H7.
2013 Cyclospora Outbreak at Olive Garden and Red Lobster
In 2013, bagged salad mix produced by Taylor Farms de Mexico and served at Olive Garden and Red Lobster restaurants caused 239 illnesses. Different food sources caused 400 more cases in 23 other states that summer, the first year Cyclospora made an appearance as the source of a major, non-travel-related foodborne outbreak in the U.S.
Taylor Farms de Mexico suspended operations for two weeks while the FDA investigated. The company received permission from the agency to restart after agreeing to implement a comprehensive Cyclospora sampling program for leafy greens and other products from their farms and processing facility in Mexico. The program was also supposed to include water sampling and continued monitoring of the sanitary conditions at the facilities
What is Cyclospora?
Cyclospora is a parasite native to tropical climates that causes illness when people consume food or water contaminated with human feces containing it. Outbreaks are frequently associated with fresh produce.
Humans are the only known species that the parasite Cyclospora infects. In the U.S., non-travel-related cases are frequently linked to imported produce. Previous Cyclospora outbreaks have been linked to bagged salad, cilantro, basil, snow peas, and berries.
What are the Symptoms of a Cyclospora Infection?
Symptoms of a Cyclospora infection, called cyclosporiasis, usually appear within 1 to 14 days of exposure. They can seem to improve and then return, making it hard for people to work, travel, care for children, attend school, or keep up with daily responsibilities. Without treatment, cyclosporiasis symptoms can last for months.
They include:
- Frequent bouts of watery, sometimes explosive diarrhea.
- Loss of appetite, weight loss
- Stomach cramps or abdominal pain
- Bloating and increased gas
- Nausea
- Fatigue that can be severe
- Vomiting, body aches, headache, or low-grade fever in some patients
Usually, these infections are not life-threatening, but dehydration from symptoms can cause severe illness, especially among children, seniors, and those with weakened immune systems.
How is Cyclosporiasis Diagnosed and Treated?
Diagnosis usually requires a stool sample. If you have sudden, ongoing diarrhea and may be part of the Michigan outbreak, tell your healthcare provider about the outbreak and ask whether Cyclospora testing should be ordered. Some stool tests do not automatically look for Cyclospora unless the provider or laboratory specifically considers it.
The CDC’s clinical care guidance states that trimethoprim-sulfamethoxazole, often called TMP-SMX, is the treatment of choice. Treatment decisions belong to your healthcare provider, especially if you have medication allergies, pregnancy concerns, immune system issues, dehydration, kidney disease, or other medical risks.
People at higher risk of dehydration or serious illness, including young children, older adults, and people with weakened immune systems, should be especially careful about prolonged diarrhea and fluid loss.
What Should You Do if You Develop Symptoms of Cyclosporiasis?
If you think you may be part of this outbreak, take these steps now:
- Get medical care and testing. Tell your provider about the Michigan Cyclospora outbreak and ask whether stool testing for Cyclospora is appropriate. Standard parasite testing may not include Cyclospora, and the MDHHS provider bulletin advises providers to ensure the stool order specifically targets Cyclospora.
- Report a positive diagnosis. If you test positive, make sure the health department is notified. Public health interviews help investigators find the source.
- Write a food history. List produce, salads, herbs, berries you ate at home, restaurants, catered meals, workplace meals, school or event meals, and travel during the two weeks before symptoms began.
- Save purchase records. Keep receipts, grocery receipts, loyalty-card records, delivery-app orders, restaurant receipts, credit-card statements, photos of packaging, product labels, and store notices. If you ate at Taco Bell or another restaurant, save the exact location, date, time, menu items, app order, payment record, and any photograph of a posted ingredient notice.
- Save medical and wage records. Keep bills, prescription receipts, discharge papers, messages with providers, missed-work records, and notes about symptom days.
- Talk to a Cyclospora attorney early. Evidence can disappear quickly in produce cases. A lawyer can help identify stores, suppliers, restaurants, and records that may connect your illness to the outbreak.
What Happened in the Michigan Cyclospora Outbreak?
MDHHS announced the Michigan outbreak on July 1 after more than 170 cases were reported during the preceding nine days. Michigan typically identifies about 40 to 50 cyclosporiasis cases during an entire year. The total reached 14,510 by August 27.
Detailed Michigan data updated August 20 show the highest reported totals in Wayne County with 2,130 cases, Oakland County with 1,599, Washtenaw County with 1,114 and Ingham County with 925.
The Michigan outbreak is part of a much larger increase in Cyclospora illnesses reported across the United States. CDC reports 17,180 laboratory-confirmed domestically acquired cases since May 1, including 922 hospitalizations and two deaths. CDC is also aware of at least 11,844 additional reports that are not laboratory confirmed or still require investigation.
Those national numbers are not directly comparable with Michigan’s total because MDHHS and CDC use different case definitions, reporting methods and update schedules. The datasets overlap, so Michigan’s cases should not be added to CDC’s national totals.
Within the broader nationwide increase, CDC and FDA have identified a more specific outbreak linked to recalled Taylor Farms de Mexico iceberg lettuce. That outbreak includes 11,458 illnesses in 20 states, 495 hospitalizations and two deaths in Michigan. Federal investigators say people in that outbreak were exposed to processed Taylor Farms lettuce served or purchased at multiple locations, including people who previously reported eating at Taco Bell.

Can I Sue if I got Cyclospora in the Michigan Outbreak?
Yes, a Cyclospora lawsuit may be possible if evidence connects your diagnosed illness to contaminated food sold or served by a company. Pritzker Hageman has a detailed guide on suing for Cyclospora food poisoning from produce, and the same evidence principles apply here: a confirmed diagnosis, proof of exposure to the implicated food, and documented damages.
For the multistate Taco Bell outbreak, public health agencies have identified an implicated food category, a recall, and a traced supply route. A potential Cyclospora lawsuit still depends on the patient’s diagnosis, exposure history, timing, restaurant or grocery records, medical evidence, and the facts connecting the illness to a legally responsible company. Michigan’s broader investigation may include illnesses from other sources. Patients should preserve Taco Bell orders, other restaurant receipts, grocery and loyalty records, packaging, payment records, health-department communications, medical test results, and wage-loss information before those records disappear.
Depending on the facts, potential defendants in a Cyclospora case can include produce growers, packing houses, processors, distributors, grocery stores, restaurants, caterers, institutional foodservice companies, or others in the supply chain.

What Damages Can a Cyclospora Lawsuit Include?
A food poisoning claim can seek compensation for the harm caused by the illness. Depending on the facts, damages may include:
- Medical bills and out-of-pocket healthcare costs
- Prescription expenses and follow-up care
- Lost wages or lost business income
- Travel costs and other expenses caused by the illness
- Pain, suffering, fatigue, and loss of normal life
- Wrongful death damages if a foodborne illness leads to death
The value of a case depends on evidence, diagnosis, length and severity of illness, medical treatment, wage loss, long-term effects, and whether investigators can link the illness to a legally responsible company.

How to Reduce the Risk of Getting Sick
MDHHS now says Michigan residents may resume routine guidance for consuming lettuce and salad greens because new case reports and diarrhea-related emergency department visits are declining. The broad precautionary recommendation to avoid bagged salad mixes is no longer in effect.
MDHHS says the outbreak data suggest that most exposures occurred in late June to early July and that the majority of the contaminated produce is likely no longer available for consumption. The state continues to recommend avoiding recalled Taylor Farms de Mexico iceberg lettuce.
Washing recalled lettuce does not make it safe to eat. Cyclospora can cling tightly to produce, and common cleaning methods such as vinegar, soap, chlorine and commercial produce washes do not destroy the parasite. Methods that do not destroy Cyclospora include several approaches consumers may assume would make contaminated produce safe.
How Public Health Interviews Can Help Identify the Source
Cyclospora investigations can be difficult because many people eat several fresh produce items during the exposure window. Health departments compare food histories from many patients to look for common products, brands, stores, restaurants, events, distributors, or suppliers. A single person’s food history may not identify the source, but many interviews together can point investigators in the right direction.
MDHHS now says it has interviewed more than 2,900 affected people. Many did not report eating lettuce at a restaurant chain or other food establishment. Lettuce still appeared often in questionnaires from people without restaurant or fast-food exposure, which supports investigating grocery stores and other foodservice channels in addition to Taco Bell. Before a health-department interview, review grocery receipts, loyalty-card records, restaurant and delivery-app orders, photographs, calendars, workplace or catered meals, and travel during the two weeks before symptoms began. These details may help investigators connect illnesses to a shared product or distribution route.
Michigan Cyclospora outbreak FAQ
Partly. Some Michigan illnesses are included in the multistate outbreak linked to Taylor Farms de Mexico iceberg lettuce. Michigan’s broader outbreak includes additional illnesses, and MDHHS has not identified one food, grower or supplier that explains every case.
According to MDHHS county-level outbreak data, Wayne and Oakland counties have reported the highest numbers of Cyclospora cases, with Washtenaw and Ingham also among the counties with the most reported illnesses. MDHHS updates county-level data regularly, so individual totals may change as the investigation continues.
Yes, but the federal outbreak is no longer limited to people who reported eating at Taco Bell. CDC and FDA now include people who reported exposure either to Taco Bell or to recalled Taylor Farms de Mexico iceberg lettuce. The finding does not apply to every Taco Bell location or every Michigan case.
Yes. Michigan is included in a multistate Cyclospora outbreak linked to recalled Taylor Farms de Mexico iceberg lettuce. That outbreak represents only part of the Cyclospora activity reported in Michigan, where state health officials continue to investigate additional illnesses that have not all been tied to the recalled lettuce.
Yes. The Taylor Fresh Foods recall includes Marketside Iceberg Salad in 12-ounce and 24-ounce bags and Marketside Shredded Lettuce in 8-ounce and 16-ounce bags, with Best If Used By dates through August 3, 2026. The listed dates have passed, but anyone who still has recalled product at home should not eat it. Additional foodservice products are also included.
The most common symptom is watery diarrhea, often frequent and sometimes explosive. Other symptoms can include loss of appetite, weight loss, stomach cramps, bloating, gas, nausea, fatigue, vomiting, body aches, headache, and low-grade fever.
Symptoms usually begin about one week after exposure, but they can start anywhere within 1 to 14 days of exposure.
Direct person-to-person spread is unlikely because Cyclospora generally needs time in the environment after leaving the body before it becomes infectious. Food or water contamination is the usual concern in outbreaks.
If you have sudden, ongoing diarrhea and may have been exposed in the Michigan outbreak, tell your provider about the outbreak and ask whether stool testing for Cyclospora is appropriate.
Cyclosporiasis is treated differently than most bacterial infections. Your healthcare provider should decide the right treatment based on your health history, medications, allergies, and symptoms.
A lawsuit may be possible if evidence connects a diagnosed illness to contaminated food sold or served by a company. Investigators have identified lettuce or salad greens as a potential source, but the particular product and supply chain remain unknown. Preserve evidence and seek legal guidance before purchase, ordering, supplier, and medical records disappear.
Save medical records, test results, receipts, loyalty-card records, delivery orders, restaurant receipts, photos of product labels, packaging, food histories, wage-loss records, and communications with health officials.
No. What matters is where and how you were exposed, whether you were diagnosed, and whether evidence links your illness to contaminated food sold or served by a responsible company. Travelers and out-of-state residents can still be part of an outbreak investigation, and contaminated food products may have been sold out of state, as well.
Call your healthcare provider for medical guidance, cooperate with your local health department, and contact Pritzker Hageman for a free legal consultation at 1-888-377-8900 or by text at 612-261-0856. You can also use our online contact form.
