The dip consists of layers of beans, fresh salsa, fresh guacamole, nacho cheese and sour cream. Shigellosis is characterized by acute onset of diarrhea, often bloody, accompanied by moderate to high fever, cramping abdominal pain and sometimes nausea and vomiting. Illness usually goes away without treatment after lasting 3-10 days.
Transmission is fecal-oral.
People get shigellosis up to seven days after eating food contaminated with Shigella ridden feces or after putting in their mouths fecally contaminated inanimate objects. People with shigellosis are contagious from one to four weeks after onset. The Oregon State Public Health Laboratory will examine feces from outbreak-related cases submitted by local health departments. Shigella culturing is, however, readily available at most clinical laboratories.
