MCKINNEY, Texas — Health officials are warning the public after a food service worker in Collin County was diagnosed with Salmonella typhi, also known as typhoid fever. 

Collin County Health Care officials say anyone who ate at Hat Creek Burger Co. at 3321 S Custer Road in McKinney between Aug. 19 through Aug. 22 could be at risk. 

Friday, officials also confirmed that a Talley Elementary School student in Frisco ISD was being tested for typhoid fever. The principal of the school sent a letter to parents assuring them the district was taking extra precautions to clean the school.

Symptoms of typhoid fever may include a fever as high as 103-104 degrees. Patients may also feel weak, have stomach pains, headache, diarrhea, or loss of appetite and constipation, officials say.

Typhoid fever is usually spread through the bacteria of a person’s stool, according to health officials. 

Health experts say the best way to prevent the spread of this illness is for people to wash their hands after using the restroom, especially people who prepare food.
