At least 15 people became ill with Salmonella infections last month after attending the Margarita Mix-Off in Chico, California. Three of the fifteen were hospitalized due to the severity of their illnesses.
The Margarita Mix-Off was hosted at Manzanita Place in Chico on May 8, with a local caterer providing food served at the event. Butte County public health officials have thus far been unable to determine the source of the outbreak despite conducting extensive interviews with people who got sick.
