Should You Avoid Fresh Produce During the Cyclosporiasis Outbreak? What Experts Say

Learn whether it's safe to eat fresh produce during the 2026 cyclosporiasis outbreak, which foods may pose a higher risk, expert recommendations, symptoms, and prevention tips.

The growing cyclosporiasis outbreak across the United States has left many consumers wondering whether it is still safe to eat fresh fruits and vegetables. With thousands of reported cases across multiple states and investigators still searching for the exact source, concerns about contaminated produce continue to rise.

Health experts agree that fresh produce remains an important part of a healthy diet. However, they also recommend taking extra precautions while preparing food until officials identify the source of the outbreak.

Here is everything you need to know about the current cyclosporiasis outbreak, the foods that may be linked to infections, expert recommendations, and practical steps to reduce your risk.

What Is Cyclosporiasis?

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. People become infected after consuming food or water contaminated with the parasite.

Unlike many foodborne illnesses, symptoms often do not appear immediately. It can take up to two weeks after exposure before people begin feeling sick. This delay makes it much harder for investigators to identify the original source of contamination.

Common symptoms include:

• Frequent watery diarrhea
• Severe stomach cramps
• Nausea and vomiting
• Fatigue
• Loss of appetite
• Weight loss
• Bloating
• Low-grade fever in some cases

While the illness is rarely life threatening, symptoms can last for several weeks without treatment and may return if left untreated.

How Large Is the Current Outbreak?

The 2026 outbreak has become one of the largest cyclosporiasis outbreaks reported in recent years.

According to the Centers for Disease Control and Prevention (CDC), there are more than 1,600 confirmed cases across 34 states, resulting in over 140 hospitalizations. The agency has also indicated that more than 5,000 additional reports require further investigation.

Michigan has reported the highest number of suspected cases, with state officials documenting more than 3,300 infections and dozens of hospitalizations. Other affected states include Illinois, Ohio, Virginia, New York, and several others.

Because reporting systems vary between states and federal agencies, official numbers continue to change as investigations progress.

What Foods Are Being Investigated?

Officials have not confirmed the exact source of the outbreak.

Historically, previous Cyclospora outbreaks have been linked to imported fresh produce, including:

• Cilantro
• Basil
• Lettuce
• Green onions
• Raspberries
• Snow peas

Michigan health officials believe lettuce may be involved in the current outbreak. Several Taco Bell locations in the state temporarily stopped serving lettuce, cilantro, onions, pico de gallo, and guacamole while investigators examined potential links.

It is important to note that this does not necessarily mean all produce or all restaurants are unsafe. Investigations remain ongoing.

Should You Stop Eating Fresh Produce?

Most food safety experts say no.

Experts emphasize that fruits and vegetables provide essential nutrients and should remain part of a balanced diet. Rather than eliminating produce completely, consumers should take additional precautions until investigators identify the contamination source.

Don Stoeckel from Cornell University's Produce Safety Alliance noted that although the outbreak is significant, it does not mean every piece of produce is contaminated.

Similarly, Rutgers University food microbiology professor Donald Schaffner recommends continuing to eat fresh produce while following proper food safety practices.

However, not all experts completely agree.

Why Some Experts Recommend Extra Caution

Some infectious disease specialists believe washing produce may not fully eliminate Cyclospora.

Professor Dana Mordue of New York Medical College explained that the parasite can cling tightly to the surface of fruits and vegetables, making it difficult to remove through washing alone.

Dr. Richard Smith, an infectious disease specialist in San Diego, has gone a step further by recommending people temporarily avoid leafy greens and salad bars until investigators determine the outbreak source.

His reasoning is simple. Heat effectively destroys the parasite, while rinsing alone may not.

For individuals who regularly consume raw salads, taking a short break may reduce exposure until public health officials release more information.

How to Reduce Your Risk

Although no method guarantees complete protection, health experts recommend several food safety measures.

Wash Your Hands

Always wash your hands thoroughly with soap and water before handling food or preparing meals.

Rinse Produce Carefully

Wash fruits and vegetables under clean running water while gently rubbing or scrubbing the surface.

Avoid using soap, bleach, or household cleaning products on produce, as these products are not intended for consumption.

Remove Outer Leaves

For leafy vegetables such as lettuce or cabbage, remove the outer leaves before eating or preparing meals.

Peel Produce When Possible

Peeling fruits and vegetables such as cucumbers, carrots, or apples may help reduce potential contamination.

Cook Foods Thoroughly

Cyclospora is sensitive to heat. Cooking vegetables when appropriate may reduce the risk of infection.

Refrigerate Perishable Foods

Store fresh produce promptly in the refrigerator after purchase to maintain food quality and reduce the growth of other harmful microorganisms.

Who Is Most at Risk?

Healthy individuals often recover completely, although symptoms can be unpleasant and prolonged.

Higher-risk groups include:

• Older adults
• Young children
• People with weakened immune systems
• Individuals receiving cancer treatment
• Organ transplant recipients
• People living with immune disorders

These individuals should seek medical attention promptly if symptoms develop.

How Is Cyclosporiasis Treated?

Most healthy adults eventually recover, but treatment can significantly shorten the illness.

Doctors commonly prescribe antibiotics containing trimethoprim-sulfamethoxazole, sold under brand names including Bactrim, Septra, and Cotrim.

People experiencing persistent diarrhea, dehydration, fever, or severe abdominal pain should contact a healthcare provider as soon as possible.

Should You Be Worried?

The current outbreak is serious enough to warrant attention but not panic.

Public health agencies continue investigating the source, and officials expect additional guidance as more evidence becomes available.

For now, experts recommend maintaining good food hygiene, staying informed through official health updates, and seeking medical care if symptoms appear after consuming fresh produce.

Fresh fruits and vegetables remain an important part of a healthy diet, and most experts believe careful handling offers reasonable protection while the investigation continues.

Frequently Asked Questions

Can washing produce remove Cyclospora?

Washing under running water may reduce contamination but may not completely remove the parasite. Proper washing is still recommended because it helps lower the risk of many foodborne illnesses.

Is cooked food safer?

Yes. Heat effectively destroys Cyclospora, making cooked vegetables generally safer than raw produce during an outbreak.

Should I avoid salad bars?

Some infectious disease experts recommend temporarily avoiding salad bars and raw leafy greens until investigators identify the outbreak source.

Which produce is considered higher risk?

Health officials are paying particular attention to lettuce, cilantro, basil, green onions, raspberries, and snow peas because similar produce has been linked to previous outbreaks.

Conclusion

The ongoing cyclosporiasis outbreak serves as an important reminder that food safety starts in every kitchen. While investigators continue searching for the contamination source, consumers do not necessarily need to eliminate fresh produce from their diets. Instead, careful washing, proper food handling, and staying updated with official public health guidance remain the best strategies for reducing risk.

As new information becomes available, recommendations may change. Monitoring updates from trusted health authorities will help consumers make informed decisions while continuing to enjoy a healthy diet.
