The Chicken and Rice Guys Chain has temporarily closed four restaurants in Boston and Medford, MA. and has idled its fleet of food trucks following a trace-back involving 14 confirmed and documented cases of E.coli O157:H7 infection.
Currently, public health officials are investigating the source of the infection but it will be approximately one week before the restaurants reopen after decontamination and assay. The focus of the investigation is the Company commissary located in Medford.
It is evident that authorities in conjunction the with FDA or the CDC will apply whole genome sequencing to positively confirm the vehicle of infection and determine whether the pathogen was introduced by an employee or through a contaminated ingredient.
