Not lovin’ it; 163 sick from crapped-in McDonald’s salads
| Aaron Gould Sheinin, WebMD – The CDC now reports 163 confirmed illnesses in people who reported eating a salad from McDonald’s. Three have been hospitalized.
McDonald’s has stopped selling salads in fourteen U.S. states and pulled lettuce blends from about 3,000 restaurants and distribution centers.
The intestinal illness is caused when people eat or drink the microscopic parasite Cyclospora cayetanensis, which can contaminate food and water.
[Many news outlets skip the fact that this parasite is spread by fecal contamination, and that the origin of the parasite is Central American counties, especially Mexico, where most US migrant farm labor comes from. – Editor]
The CDC has found 61 laboratory-confirmed cases in seven states:
- South Dakota
In each, the affected patient said they ate a salad from McDonald’s.
McDonald’s has stopped selling salads in restaurants in those states, as well as in seven more:
- North Dakota
- West Virginia

More parasitic infections linked to Del Monte, McDonalds

At least 400 people have been infected by Cyclospora parasites in two separate outbreaks associated with vegetable-dip trays from Del Monte and salads from McDonald’s.
There isn’t any evidence to indicate the two multi-state outbreaks are related, according to the Food and Drug Administration and the Centers for Disease Control and Prevention.
The CDC reported this week that 163 people across 10 states have laboratory-confirmed infections in the outbreak linked to salads from McDonald’s. The agency reported 237 people with confirmed infections in four states in the outbreak linked to pre-cut vegetable trays from Del Monte.
Victim counts are expected to continue to increase, partly because it can take up two weeks or longer for infected people to develop symptoms. There is also lag time of up to six weeks in cyclosporiasis cases between when a person is initially diagnosed and when lab-confirmation of their illnesses is reported to the CDC.
Consequently, people who became sick after June 7 may not yet be included in the federal agency’s case count for either outbreak.
Although there is strong epidemiological evidence that the salads and vegetable trays are the source of the Cyclospora, FDA officials reported this week that they have not yet identified a specific ingredient in any of the products that is the source of the parasitic contamination.
In recent years there have been a number of outbreaks caused by Cyclospora parasites. Most have been traced to fresh produce that was not cooked before it was consumed.
Federal officials said they have not received any reports of confirmed deaths in either outbreak.
At least three people sickened in the outbreak associated with salads from McDonald’s had such severe symptoms they had to be hospitalized. The 163 victims have illness onset dates beginning on or after May 1 through July 10.
The infected people range in age from 16 to 87 years old. Two-thirds of them are female, according to the CDC.
State health officials in 10 states have confirmed people with infections. However, the one sick person reported by Florida officials ate a McDonald’s salad from a restaurant in Kentucky.
“Anyone who consumed salads from McDonald’s in Iowa, Illinois, Kentucky, Minnesota, Missouri, Nebraska, Ohio, South Dakota and Wisconsin could have been exposed to the pathogen,” according to the FDA’s investigation update.
“The FDA is working with McDonald’s to identify the common ingredients in the salads identified by those who became sick and to trace back those ingredients through the supply chain.”
The multi-national restaurant chain pulled “lettuce blends” from about 3,000 stores in 14 states, according to a statement on the corporate website.
Of the 3,000 restaurants, at least one is located in the following states: Illinois, Iowa, Indiana, Wisconsin, Michigan, Ohio, Minnesota, Nebraska, South Dakota, Montana, North Dakota, Kentucky, West Virginia and Missouri.
Del Monte vegetable-dip trays
Of the 237 people with laboratory-confirmed infections in the outbreak associated with Del Monte pre-cut vegetable trays, seven have had symptoms so severe that they had to be hospitalized, according to the CDC.
Illness onset dates in the outbreak range from May 14 through June 13. The sick people are 13 to 79 years old. Fifty-three percent of the confirmed ill people are female.
“Most ill people reported buying pre-packaged Del Monte Fresh Produce vegetable trays containing broccoli, cauliflower, carrots, and dill dip in the Midwest. Most people reported buying the trays at Kwik Trip convenience stores,” according to the CDC.
Del Monte recalled the implicated vegetable trays June 15. The multi-national company reported distributing the pre-cut, fresh vegetable products to Kwik Trip, Kwik Star, Demond’s, Sentry, Potash, Meehan’s, Country Market, FoodMax Supermarket, and Peapod.
People with confirmed infections live in Iowa, Minnesota, Michigan and Wisconsin.
Advice to consumers
Anyone who has eaten a McDonald’s salad or any items from the recalled Del Monte vegetable-dip trays and developed symptoms of cyclosporiasis should seek medical attention and tell their doctors about their possible exposure to Cyclospora parasites.
Symptoms usually include 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.
Some people who are infected with Cyclospora parasites do not have any symptoms. If not treated, the illness may last from a few days to a month or longer. Symptoms may seem to go away and then return one or more times, making diagnosis difficult.
“The Cyclospora parasite needs time — days to weeks — after being passed in a bowel movement to become infectious for another person,” according to the FDA. “Therefore, it is unlikely that cyclosporiasis is passed directly from one person to another.”
Cyclospora parasites can contaminate foods or beverages, but in the United States they are most often found on fresh produce, according to federal officials.
