McDonald's Pulls Salads In Minnesota Over Parasite Outbreak

MINNESOTA — State and federal health officials are investigating a multi-state outbreak of cyclosporiasis illnesses linked to salads from McDonald’s restaurants. At least 61 people in seven states, including Minnesota, have become ill.

Cyclosporiasis is a parasite that causes intestinal illness. It's not clear how many are sick in Minnesota.

There have been two hospitalizations and no deaths overall, according to the Centers for Disease Control.

McDonald’s Friday said it has decided to stop selling salads in Minnesota and other states seeing an increase in cyclospora infections.

"Out of an abundance of caution, we decided to voluntarily stop selling salads at impacted restaurants until we can switch to another lettuce blend supplier," the fast-food restaurant chain said in a statement.

"We are in the process of removing existing lettuce blend from identified restaurants and distribution centers – which includes approximately 3,000 of our U.S. restaurants primarily located in the Midwest."

Earlier this year, a separate outbreak of cyclospora in Minnesota was linked to vegetable trays purchased at Kwik Trip locations and a Minneapolis restaurant.

Washing of imported produce, or routine chemical disinfection or sanitizing methods, are unlikely to kill Cyclospora.

Symptoms typically include watery diarrhea, stomach cramps, nausea, loss of appetite and weight loss. People typically become ill about a week after exposure, but this period can range from 2-14 days. Diarrhea can last several weeks or longer if not treated.
