Article Excerpts About Symptoms of Food poisoning:
Bacteria and Foodborne Illness: NIDDK (Excerpt)
In most cases of foodborne illness, symptoms
resemble intestinal flu and may last a few hours or even several days.
Symptoms can range from mild to serious and include
- Abdominal cramps
(Source: excerpt from Bacteria and Foodborne Illness: NIDDK
Foodborne Infections General: DBMD (Excerpt)
After they are swallowed, there is a delay, called the
incubation period, before the symptoms of illness begin.
This delay may range from hours to days, depending on the organism,
and on how many of them were swallowed. During the incubation
period, the microbes pass through the stomach into the intestine,
attach to the cells lining the intestinal walls, and begin to
multiply there. Some types of microbes stay in the intestine,
some produce a toxin that is absorbed into the bloodstream, and
some can directly invade the deeper body tissues. The symptoms
produced depend greatly on the type of microbe. Numerous organisms
cause similar symptoms, especially diarrhea, abdominal cramps,
and nausea. There is so much overlap that it is rarely possible
to say which microbe is likely to be causing a given illness unless
laboratory tests are done to identify the microbe, or unless the
illness is part of a recognized outbreak. (Source: excerpt from Foodborne Infections General: DBMD)

Symptoms vary widely depending on etiologic
