The Food Poisoning Incident

Sorry 'bout the salmonella.

Exactly What It Says on the Tin.

Pretty simple, really:

Someone eats bad food and doesn't know it. (Unless they are Homer Simpson).

Sometimes, they think they ate bad food and panic.

Occasionally, are horrified that they fed their family bad food.

Once in a while, it will be seemingly Ripped from the Headlines (the All in The Family example came not long after a botulism scare on the east coast).

May be considered a Sub-Trope to Amusing Injuries.

Compare to Cowboy Bebop: Mushroom Samba.

May overlap with Last Day to Live. May lead to a Vomit Chain Reaction, as with the 6teen example.

For some reason, often Played for Laughs.

It is suggested that this may be because the symptoms are usually of the distressing-cum-embarrassing sort (nausea, diarrhea, vomiting), and in part because of anxiety over E.Coli and the like. Either way, it's a pointed reminder of how much we rely upon our bodies. "For surely laughter masks a nervous soul."

Some shows seem to use this trope especially. It has been observed that The Simpsons use it to shift the Character Focus of the episode by eliminating not needed characters. Examples: the oysters eliminated everyone leaving only Bart & Skinner, on which the episode was focused. (They even acknowledged that it made no sense that Lisa got ill but they just Handwaved it.) The vegetables make the whole family sick so Lisa started her singing career.

• In My Little Pony Friendship Is Magic, "Applebuck Season", a sleep-deprived Applejack tries to help Pinkie Pie with baking muffins, but gets the ingredients ridiculously wrong, replacing chocolate chips with potato chips, baking soda with soda pop, a cup of flour with "a cup of sour" (lemon juice), and wheat germ with "wheat worms" (earthworms from a mud puddle out back).
• Inverted in an episode of SpongeBob SquarePants - the titular sponge is thought to have unknowingly eaten a deadly pie, which will end his life at sunset. Squidward, responsible for bringing a pie-shaped bomb to Spongebob, feels guilty enough to spend the rest of the day doing anything Spongebob wants.

  • A more straightforward example is when Mr. Krabs sells spoiled Krabby Patties that have turned yellow and spongy as an attempt to cash in on SpongeBob's popularity.
