Salmonella Blog Surveillance & Analysis on Salmonella News & Outbreaks

Will the CDC name Taco Bell as the “Mexican-style fast food restaurant chain” associated with some Salmonella Hartford and Baildon illnesses?”

Today the CDC announced that it is investigating two multistate outbreaks of Salmonella infections, each involving a different Salmonella serotype: Hartford and Baildon.  An analysis indicates that eating at a Mexican-style fast food restaurant chain, Restaurant Chain A, is associated with some illnesses. Among persons eating at Restaurant Chain A, no specific food item or ingredient was found to be associated with illness for either outbreak.  An extensive traceback effort was initiated to determine if a common source or supplier could be identified to help focus the epidemiologic investigations. No common food source was identified in either traceback.

Interestingly, we have been tracking both Salmonella Hartford and Baildon illnesses in several states in the preceding months.  Many of those ill recall (long-prior to the CDC announcement) eating at a Taco Bell.  Several of those in Kentucky.  We continue our investigation.  Here are the details from the CDC:

Salmonella Hartford Outbreak Investigation

As of August 1, 2010, a total of 75 individuals infected with a matching strain of Salmonella Hartford have been reported from 15 states since April 1, 2010.

Among those for whom information is available about when symptoms started, illnesses began between April 30, 2010 and July 18, 2010. Case-patients range in age from <1 to 80 years old, and the median age is 39 years. Fifty-seven percent of patients are female. Among the 47 patients with available hospitalization information, 15 (32 %) were hospitalized. No deaths have been reported.

Salmonella Baildon Outbreak Investigation
