80 Cases of Cyclospora Reported in Massachusetts

Posted in Cyclospora,Cyclospora,Our Blog,Outbreaks & Recalls on July 17, 2019

Massachusetts Department of Public Health announced this week that it is actively investigating a Massachusetts Cyclospora Outbreak. At this time, no food source has been identified. However, the MDPH is collaborating with the Centers for Disease Control to identify possible sources of exposure to the parasite.

The Outbreak

The MDPH reports that “most of the cases have been reported in eastern Massachusetts, specifically in the greater Boston area.”

“More than 80 cases of the intestinal illness Cyclosporiasis have been reported since May,” said Dr. Larry Maddoff, medical director for the Bureau of Infectious Diseases and Laboratory Sciences at the Massachusetts Department of Public Health.

About Cyclospora

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. People can become infected with Cyclospora by consuming food or water contaminated with the parasite. People living or traveling in countries where cyclosporiasis is endemic may be at increased risk for infection.

Its symptoms:

It generally spreads through fresh fruits and vegetables like lettuce, cilantro, basil, berries etc. It’s difficult to diagnose the parasitic infection unless a specialized stool test is performed. The treatment is generally done through antibiotics.


  • Frequent bouts of watery diarrhea
  • Loss of appetite and weight
  • Abdominal cramps, bloating and flatulence
  • Nausea and vomiting
  • Low grade fever

Cyclospora spreads through fecal contamination. It happens when contaminated water comes in contact with fresh produce or when an employee doesn’t wash his hands and touches the fresh produce. The latter can cause contamination at all stages – from growing to handling produce while cooking. The only way to prevent contamination is to maintain proper hygiene at all stages of food processing. Use safe and clean water during irrigation and make sure that employees who handle food directly properly wash their hands after going to the washroom.


According to the MDPH, “If you think you have cyclosporiasis, you should see a doctor. Your doctor can take a stool sample and send it to a laboratory for testing. If you have cyclospora in your stool, you may be treated with antibiotics or a combination of antibiotics. If you have diarrhea, you should rest and drink plenty of clear fluids. Do not take any medicine until asking your doctor about it. People who have already had a cyclospora infection can get it again.”


The CDC mentions on its website: “Trimethoprim/sulfamethoxazole (TMP/SMX), sold under the trade names Bactrim*, Septra*, and Cotrim*, is the usual therapy for Cyclospora infection. No highly effective alternative antibiotic regimen has been identified yet for patients who do not respond to the standard treatment or have a sulfa allergy.”

Recommendations for Retailers and Food Service

The FDA has issued recommendations for retailers during a cyclospora outbreak:

“Based on current information available Cyclospora may be resistant to routine chemical disinfection methods such as those using chlorine. However, restaurants and retailers should still follow basic food safety practices:

  • Retailers, restaurants, and other food service operators should always practice safe food handling and preparation measures. It is recommended that they wash utensils, and surfaces with hot, soapy water before and after handling food. Wash and sanitize display cases and refrigerators where potentially contaminated products were stored.
  • Wash and sanitize cutting boards, surfaces, and utensils used to prepare, serve, or store potentially contaminated products.
  • Wash hands with warm water and soap following the cleaning and sanitation process.
  • Regular frequent cleaning and sanitizing of food contact surfaces and utensils used in food preparation may help to minimize the likelihood of cross-contamination.”

As for consumers, they recommend:

“Consumers who have symptoms of cyclosporiasis should contact their health care provider to report their symptoms and receive care. Most people infected with Cyclospora develop diarrhea, with frequent, sometimes explosive, bowel movements. Other common symptoms include loss of appetite, weight loss, stomach cramps/pain, bloating, increased gas, nausea, and fatigue. Vomiting, body aches, headache, fever, and other flu-like symptoms may be noted.”


The Massachusetts Department of Public Health recommends that anyone who has become sick with cyclospora report their illnesses to the health department. Health care providers are required by law to report cases of cyclosporiasis to the local board of health. According to the MDPH, “In order to protect the public, workers at food-related businesses who have cyclospora in their stool, must stay out of work until they don’t have diarrhea and lab tests on one to two different stool samples show that there are no cyclospora germs. Workers in food-related businesses who have diarrhea and live with someone who has cyclosporiasis must also show that they have none of the germs in their stool. Food-related businesses include restaurants, sandwich shops, hospital kitchens, supermarkets, dairy or food-processing plants. This regulation also includes workers in schools, residential programs, day-care and health care facilities, that feed, give mouth care or dispense medications to clients.”
