Question:
Stage 1: Maria and her two grandchildren started feeling unwell with
stomach cramps, diarrhea, and fever after eating raw cookie dough. We
will look at what caused their illness, how doctors figured it out, and how

irritation symptoms
b) Ingesting contaminated raw eggs allowing Salmonella to invade
intestinal mucosa
c) Consuming contaminated food leading to rapid toxin-mediated vomiting
symptoms
d) Ingesting improperly stored food leading to toxin production before
consumption
Answer:
Ingesting contaminated raw eggs allowing Salmonella to invade intestinal
mucosa
, Question:
Which findings from the scenario support a bacterial infection rather than
intoxication? Select all that apply.
a) Symptoms resolving quickly after removal of contaminated food source
b) Evidence of bacterial invasion causing inflammation within intestinal
lining
c) Identification of gram-negative motile bacilli in collected stool samples
d) Immediate vomiting occurring within one hour after consuming
contaminated food
e) Symptoms beginning twenty hours after ingestion of contaminated
cookie dough
Answer:
Evidence of bacterial invasion causing inflammation within intestinal lining
Identification of gram-negative motile bacilli in collected stool samples
Symptoms beginning twenty hours after ingestion of contaminated cookie
dough
