    Area of Science:

    • Microbiology
    • Public Health
    • Epidemiology

    Background:

    • Outbreaks of foodborne illness can occur after private gatherings.
    • Group A Streptococcus (GAS) can cause various infections, including pharyngitis.

    Purpose of the Study:

    • To identify the cause and source of an illness outbreak following a private party.
    • To investigate the association between food consumption and illness.

    Main Methods:

    • Descriptive epidemiological investigation of attendees.
    • Microbiological analysis of throat cultures and food samples.
    • Statistical analysis to determine significant associations.

    Main Results:

    • 23 out of 47 (56%) attendees developed symptoms including fever, headache, myalgia, fatigue, and pharyngitis.

  • Consumption of carrucho (conch) salad was significantly associated with illness (P = 0.013).
  • Group A beta-hemolytic streptococci (M nontypable T12, SOF+) were isolated from 11 attendees and the conch salad.

    • Conclusions:

    • The conch salad was the likely vehicle for transmission of Group A Streptococcus.
    • Prompt recognition of such outbreaks is crucial for public health to prevent complications.
