ATLANTA — Health officials are investigating a multistate outbreak of a foodborne parasite that has sickened hundreds of people across the United States, prompting renewed warnings about properly washing fresh fruits and vegetables before consumption.
According to the U.S. Centers for Disease Control and Prevention (CDC), more than 840 confirmed cases of cyclosporiasis have been reported across 31 states since May. Investigators are continuing to search for the source of the outbreak, but no single food item has yet been identified.
While California has recorded a small number of cyclosporiasis cases this year, state health officials say those infections have not been linked to the ongoing multistate outbreak.
More Than 840 Cases Reported Across 31 States
Health authorities say the outbreak involves Cyclospora cayetanensis, a microscopic parasite that infects the digestive system after a person consumes contaminated food or water.
Unlike many common stomach illnesses, cyclosporiasis does not spread from person to person. Instead, infections typically occur when fresh produce or drinking water becomes contaminated before being consumed.
Federal investigators continue tracing possible food sources while urging consumers to practice safe food handling at home.
California Cases Not Connected to National Outbreak
Although several Californians have been diagnosed with cyclosporiasis this year, public health officials say there is currently no evidence connecting those cases to the larger outbreak affecting dozens of states.
Officials continue monitoring new reports while working with federal agencies to determine whether contaminated produce distributed across multiple states may be responsible.
The investigation remains active, and authorities say additional cases could be identified as surveillance continues.
Woman Describes Severe Illness After Infection
A Southern California woman who recently recovered from the illness described the infection as one of the worst experiences of her life.
Speaking to KTLA, the woman, who asked not to be identified, said her symptoms became severe within days.
“It was the sickest I’ve ever been. I’ve never felt that sick before.”
She said she experienced intense stomach pain, persistent vomiting and severe diarrhea that made it impossible to eat or drink normally.
“It was coming out of both ends. Every time I tried to eat, it was like a stabbing pain in my stomach, and I couldn’t keep anything down.”
According to the woman, she lost nearly 10 pounds in about one week before seeking medical care.
After doctors diagnosed cyclosporiasis, she was prescribed antibiotics and said her condition improved rapidly.
“Within about a week I was perfectly fine.”
Doctors Explain Common Symptoms
Dr. Ariel Malamud, a gastroenterologist, said symptoms usually develop five to seven days after a person becomes infected.
According to medical experts, the most common symptoms include:
- Watery or explosive diarrhea
- Nausea and vomiting
- Abdominal cramps and stomach pain
- Low-grade fever
- Fatigue and loss of appetite
Doctors warn that without treatment, symptoms can continue for several weeks or temporarily improve before returning again.
Health experts say antibiotics are generally effective once the infection has been properly diagnosed.
“If you get diarrhea, go for an evaluation,” Dr. Malamud advised. “Do your stool studies so we can get an answer of what we’re dealing with and treat you appropriately.”
Previous Outbreaks Linked to Fresh Produce
Investigators have not yet identified which food item is responsible for this year’s outbreak.
However, previous cyclosporiasis outbreaks have been associated with several types of fresh produce, including:
- Cilantro
- Basil
- Raspberries
- Leafy greens
Because the parasite can contaminate produce before it reaches grocery stores, health officials say consumers should take extra precautions when preparing fresh fruits and vegetables.
Food Safety Experts Recommend Proper Produce Washing
Food safety expert Candice Christian said careful handling of produce at home can significantly reduce the risk of foodborne illness.
She recommends scrubbing firm fruits and vegetables such as melons and cucumbers with a clean vegetable brush instead of simply rinsing them under water.
Health officials also advise consumers to:
- Wash all fruits and vegetables thoroughly under running water.
- Peel produce whenever possible.
- Choose whole heads of lettuce instead of pre-shredded bagged greens.
- Cook produce when practical to help reduce contamination risks.
Although washing produce cannot eliminate every possible hazard, experts say it remains one of the most effective steps consumers can take to lower their risk of infection.
Investigation Continues as Officials Search for Source
Federal and state health officials continue working to determine what caused the multistate outbreak and whether additional cases are connected to a common food source.
Consumers experiencing persistent diarrhea, severe stomach pain, vomiting or dehydration after eating fresh produce are encouraged to seek medical attention promptly, particularly if symptoms continue for several days.
Authorities say identifying the contaminated food responsible for the outbreak remains a top priority as investigators work to prevent additional illnesses.
