Tampering with Food and Drink

"Ah ha ha, I put broken glass in your dinner dear It's only getting worse from here"

- King Diamond, "More Than Pain"

The act of sneaking inedible or dangerous objects, such as glass, poison, drugs, etc. into an item of food or drink, with the hope that it kills/harms whomever has the misfortune to consume it.

The non-lethal version of food tampering would be putting a love potion, sleeping potion/drug, etc. in food or more commonly, drinks; also known as Slipping a Mickey. And then there's the Laxative Prank.

If the perpetrator is unlucky, his plans may be thwarted by a Poisoned Chalice Switcheroo.

A character who suspects that the trope is going to be played on him might react with a Discreet Drink Disposal or Discreet Dining Disposal.

Compare the larger scale Water Source Tampering, usually perpetrated by conspiracies and such.

Razor Apples overlaps with this trope.

It still makes him quite sick for a while, and when Shuurei finally finds out, she's torn between being impressed that he basically took the bullet for her, and being angry at him for taking such a risk. (Not because she's got feelings for him, or anything - it's just that the civil war that would result from his death would be really bad for the people. That's all, really!)

 * Additionally, she also poisoned a half-eaten bar of chocolate and switched it with one that was given to the victim as Valentines gift by his girlfriend, in an attempt to frame the girlfriend since the lady knew the victim would take a bite of his chocolatey "enemy" to please her.

The poisoner then put the antidote for the poison in the water pitchers.

Real Life

 * Often referred to colloquially as "slipping a Mickey" (or Mickey Finn) into a drink. In theory, Mickey Finn is supposed to be one specific poison (chloral hydrate, an anaesthetic drug that leaves the victim with the mother of all hangovers if they survive), but the expression is often more loosely applied to any poison in a drink.
 * Women are warned often to not leave their drinks unattended, due to fear of date rape drugs being placed into them.
 * These are also a good reason not to pick up an unattended drink at the kind of place this might happen (e.g. a frat party). More than a few male revelers have accidentally found themselves taking a drink intended for someone else.
 * Also, some delinquents of both genders often slip sleeping meds in the drinks of their dates not to rape them, but to steal whatever they have on.
 * The Roman Emperor Nero had a particularly devious twist on this: When he wanted to kill his brother Brittanicus, he didn't poison the wine, as he knew that the food tasters would detect it first. Instead, he served hot wine at the banquet, then poisoned the cooling water instead...

 * Antifreeze is one of the most commonly used chemicals to poison people. Not only is it easy to obtain, it has a sweet, syrupy flavor (due to the ethylene glycol in it) that doesn't raise suspicion if mixed in with someone's coffee- until they drop dead from heart failure.
 * There are two variants of antifreeze, the other based on propylene glycol, which is almost exactly similar, but non-toxic. It's somewhat more expensive and trickier to use (it oxidizes into mildly corrosive lactic acid on contact with air, and tends to foul up quicker), but can sometimes be more frequently encountered nowadays, specifically because it's so much safer than ethylene glycol. So the enterprising poisoner might find their plans unexpectedly failing.
 * What's more, ethylene glycol-based antifreezes now include a bittering agent to prevent deliberate and accidental poisonings, so all those wannabe Black Widows out there will just have to find some other way to cash in on their husbands' life insurance policies.
