The specific type of Salmonella involved in this outbreak is a rare serotype called Hvittingfoss. Typically, only one to two cases of this type of Salmonella are seen in Illinois per year. SUBWAY® restaurant owners and corporate representatives have been cooperating with public health officials to determine the source of these illnesses. The Illinois Department of Public Health (IDPH) will continue to work closely with local health departments and the SUBWAY® restaurant chain on this ongoing investigation.
Although there has been no positive or confirmed association with a specific product, the SUBWAY® restaurant chain has voluntarily withdrawn all lettuce, green peppers, red onion and tomatoes, from the suspected dates from its restaurants and has replaced the product with new, fresh produce. The SUBWAY® brand will continue to work with the Illinois Department of Public Health to assist in pinpointing the exact cause of the outbreak.
Symptoms of Salmonellosis (illness caused by Salmonella bacteria) include diarrhea, vomiting, fever and/or stomach cramps. Illness usually develops within six to 72 hours after being exposed to Salmonella bacteria and generally lasts three to seven days. Some individuals who are infected may have no symptoms at all but may still transmit theSalmonella bacteria to others. The spread of Salmonella from person to person may be avoided by careful hand washing with soap and water, particularly after using the restroom.
The Department encourages anyone experiencing gastrointestinal illness within six to 72 hours after eating at Subway restaurants in Illinois on or after May 10, 2010 to contact their health care provider or local health department.
