Sally was making marinated shish-kabobs to grill for dinner. She made a beautiful marinade and
then cut up the raw chicken on a cutting board. She put the chunks of chicken in the marinade
and let it sit on the counter for about three hours until it was time to cook. While the chicken was
marinating, Sally prepared the vegetables. She cut them using the same cutting board and knife.
She rinsed both the cutting board and knife off with warm water between cutting the chicken and
the vegetables. Once the chicken had marinated, Sally put the chicken and vegetables on skewers
to be grilled. She also started rice in the rice cooker to go with the shish-kabobs. As the shish-
kabobs were grilling, Sally put the marinade in a serving dish for extra sauce to put over the rice.
Several hours later, Sally and her family members all developed nausea, vomiting, diarrhea,
fever, headache, and abdominal pain.
What could be the cause of Sally and her family members' illness?
How could this illness have been prevented?
Is it E coli or Salmonella?
Could it be something else?
Solution
1) From the information given in the text, the reason for Sally and her family members' illness
might be RAW Marinade served as a sauce on rice.
Raw marinade might contain E. Coli or Salmonella which came from raw chicken, as chicken is
cooked or grilled properly, bacteria from chicken were dead leaving behind some bacteria in
marinade.
2) This illness might be prevented by cooking marinade and converted into it cooked sauce or
gravy.
Process of cooking sauce might have killed all bacteria from chicken.
3) Both possibilities are there as both E. coli and Salmonella infection shows similar kind of
effects on Patients body as mentioned in text. But chances Salmonella infection are more as,
Salmonella infection starts within 12 to 48 Hours of bacteria exposure while E. Coli Infection
takes 3 to 4 days to show initial symptoms of infection.
4) Chances of something else are also there for example, drinking water also a source of
Infection, to conclude upon 4th question more input is needed.
