A prep cook lives with a household member who was just diagnosed with a Shigella infection. What is the reporting window the Food Code sets for that exposure?

a.Within the past 24 hours of the last exposure
b.Within the past 2 days of the last exposure
c.Within the past 3 days of the last exposure
d.Within the past 30 days of the last exposure

解析

Exposure to Shigella spp. or Shiga toxin-producing E. coli is reportable within the past 3 days of the last exposure. Norovirus uses a 48-hour window, typhoid fever uses 14 days, and hepatitis A uses 30 days, so the length of the window depends on the pathogen's incubation period.

法律依据: FDA Food Code §2-201.11
