"Ah ha ha, I put broken glass in your dinner, dear
It's only getting worse from here."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. Another less fatal prank is switching the victim's usual drink with Blazing Inferno Hellfire Sauce or Gargle Blaster. A Laxative Prank is also fairly common. Well-intentioned tampering can also administer a remedy to a patient either unaware of their ailment or unwilling to take the cure. Attempting to do this to several different people at once can overlap with One Dose Fits All. A variant of this trope is Medication Tampering. It is common for the perpetrator to be a waiter/chef and the victim to be a rude customer or food critic who made the perpetrator angry. 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 and Slipping a Mickey overlap with this trope.

Anime & Manga
- Sakura Gari:
- At one point, Sakurako feeds Masataka a piece of sushi. He quickly spits it out, revealing that Sakurako had snuck in a piece of glass.
- Later, Katsuragi invites Masataka over to his home and gives him a cup of tea laced with a sleeping drug. He then rapes, beats up and tortures Masataka out of jealousy over Souma.
- It's later revealed that Sakurako, who heavily resents her father for locking her away, convinced Katsuragi to slowly poison Lord Saiki by slipping him little bits of poison in his food. Had Katsuragi not gotten his "just desserts" at the hands of Souma and his own wife Asayo, the old man would've eventually died of both poisoning and his already present bad health.
- Subverted at some point: Sakurako ties up Masataka to a chair and force feeds him, with Masataka expecting her to have slipped stuff in it again... but it's perfectly untouched food, and she made him believe it was tampered with to bully him.

- When Princess Charlotte de Orleans aka Tabitha was younger, she was at a party with her family where a strange man gave her a glass of wine. Tabitha's mother, meanwhile, saw the man smirk as he walked away. She immediately recognized a potion in the wine and took the glass Tabitha held; she drank the potion in order to save Tabitha, and became mentally ill as a consequence. She regained sanity at the end thanks to an antidote, though.
- An example where this trope is used to actually save someone and not harm him/her includes Saito slipping sleeping potion into Louise's wine at their supposed "marriage ceremony" to make her run away and not face the danger of 7,000 Zombie soldiers.

- In Saiunkoku Monogatari, Shuurei is the subject of repeated poisoning attempts during her time as Imperial Concubine. In the most notable instance she's presented with a cup of poisoned sake during a banquet; immediately suspicious but aware that refusing the offer would be a grave insult, Ryuuki drinks it in her place, counting on his better constitution and Acquired Poison Immunity to get him through it. 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!)
- In Pumpkin Scissors, one episode features a visiting princess from a neighboring country, with a particularly draconian rule of succession: Whichever royal child survives, takes the throne. Poison is a favored means of sibling rivalry, and she reveals that on her 10th birthday, the cake was poisoned, causing the death of her favorite maid. The fear of poison is so in-grown in her, that even when eating a hot-dog at a street-stand, where nobody knows who or what she is, she can't take a bite until somebody has tasted it for her first.
- The sociopathic protagonist in Suehiro Maruo's short Poison Strawberry puts thumb tacks in her classmate's milk. What happens next is horrific.
- This a rather common killing method in Detective Conan. In example...:
- A filler Valentine's Day episode had a mother try to collect insurance money by poisoning her Jerkass-ish adopted son's coffee. The antidote was in the cake's icing—the lad, being on his uni's tennis team and professing hate for all kind of sweets, didn't eat the cake. 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 crush, in an attempt to frame the girl since the lady knew the victim would take a bite of his chocolatey "enemy" to please her. And even more: a "friend" of the victim tried to tamper with the guy's cigarettes via poisoning the filters, but he just cut said filters off in a whim and thus he failed.
- Another case has Ran falling victim to poisoned coffee and then almost being drowned to death by the killer of the week. In a subversion, the guy didn't want to kill her, only knock out whoever drank the poisoned coffee to give himself an alibi.
- Subverted when a Jerk Ass Idol Singer fell dead after eating some rice balls... but the poison was not originally in said snacks. It was placed in a specific spot of his jacket: the killer knew that the guy liked to melodramatically take off said jacket before singing, so they put it in that spot so he'd touch the venom and 'transfer' it to the rice balls when he grabbed them to eat them.
- Subverted in Detective School Q, where a food critic is found dead in front of his almost untouched dinner. There was zero poison in the food; the victim actually was strangled by the assistant he just fired in very humiliating circumstances. The meals were made with out-of-due ingredients to cover up details about the time of death.
- In Naruto, Tsunade poisons Jiraiya's drink, leaving him unable to fight at full strength against Orochimaru. It is implied that she was leaning toward accepting Orochimaru's offer at the time, then changed her mind later.

- The Fatal Fury anime has two examples:
- In the first anime special, Geese forces his sort-of protegé Lily to give Terry a bottle of poisoned wine. Lily, who has fallen for Terry and feels terrible because Geese used her to kill Terry and Andy's father years ago, cannot bring herself to let Terry fall in the trap and stops him from consuming it. Then she explains what happened and gives him Anguished Declaration of Love.
- In the Motion Picture, Terry and Joe drink wine laced with sleeping drugs and are completely indefense when Panni and Hauer attack. Mai and Andy are still conscious, though, and they decide to fight back...
- Happens plenty of times in Ooku: The Inner Chambers:
- Hisamichi slipped poison into the food and drink of Yoshimune's older sisters and the closest rival to the throne to ensure that Yoshimune got the shogunate. She had to clarify that she did not do that to Ietsugu, as Ietsugu was an Ill Girl and not expected to make it to adulthood.
- Tokugawa Harusada, mother of Shogun Ienari, is quite fond of doing this to pick off rivals and control people. Her Moral Event Horizon was when she slipped poison into her grandchildren's sweets to kill them and turn her son's wife (Shigu) and favorite concubine (O-Shiga) against each other. What's worse is it's implied she did that because she was bored.
- However, Shigu and O-Shiga quickly figured out Harusada was behind those deaths and played a long game to poison Harusada in revenge. Part of that involved O-Shiga, now Harusada's taster, poisoning herself to ensure that Harusada would eat the poisoned food. She died not long after the poisoning finally incapacitated Harusada.
- Unfortunately, this left a nasty legacy on Ienari's reign: his concubines quickly realized poisoning rivals was a quick way to get ahead, with the result that only about half of Ienari's numerous children made it to adulthood.
- In Mythical Detective Loki Ragnarok Skuld tries to do this to Loki on two occasions, and fails miserably both times (in one incident, the person she brainwashed into delivering the poisoned food proceeded to explain what the food had been doped with immediately after delivery).

- In Casino Royale (2006), James Bond gets an absolutely fatal dose of digitalis in his drink. It's subverted with the defibrillator/first aid kit in his car, and that in turn is subverted when he doesn't have it connected properly! Vesper Lynd's arrival was just dumb luck.
- Wild Things: Double Subverted. When after all the backstabbing between the conspirators only a final guy and girl are left, the guy is smart enough to expect the drink he's offered to be poisoned, but is assured when the girl tells him that she would be an idiot to try it because he's the only one who can pilot the sailboat they're on back to shore.

- At the climactic Elstyn family meeting in Aunt Dimity Takes a Holiday, only Simon, the recipient of the threatening notes, takes a cup of tea offered by the maid.

They go back and forth on who should eat it for quite some time (Mort, because he can't leave until someone dies, even says "Would someone just eat it?"), but finally the Grand Vizier has to eat it, then tries to leave, leading to this:
Grand Vizier: Urgent matters of state, my lord.Emperor: Would these be the urgent matters of state in a little bottle marked "Antidote" on your dresser?
- Tampering with food and drink was also a popular tactic of the wizards in the early books (before they mellowed out and became a satire of modern academia). There was even a saying: When a wizard is tired of looking for broken glass in his dinner, he is tired of life.

"Barbarians didn't poison food. You never knew when you might be short of a mouthful yourself."
- A similar thing happens in Mort.

- In Summers at Castle Auburn, the Crown Prince is poisoned at his wedding feast, despite his using a taste tester and without anyone else at the feast dying. Only two people figured out who did it, and only one of them figured out how: The poisoner put the poison in the main course, which the prince was certain to have a large helping. The poisoner then put the antidote for the poison in the water pitchers. Since the prince never drank water (due to a paranoid belief that someone had tried to poison the well years previous, despite considerable evidence to the contrary), he was the only person at the feast who took the poison but did not take the antidote as well.
- In Robert E. Howard's Conan the Barbarian story "Shadows In Zamboula", Zabibi slips her lover something. It drives him into a frenzy, which is not the effect she intended. (What, exactly, she did intend—well, the stories thrown about are numerous.)

What saves her life is the arrival of the hero, just after she's poured some milk out into a saucer for the cat. As the two sit and chat, he is horrified to see that the cat has died after drinking the tainted milk.
- In Grave Peril, the Red Court vampires spike the drinks at Bianca's party with vampire saliva, so that any human who imbibes will become subject to its narcotic effects. Naturally, Harry isn't warned about this until after he's knocked back a glassful.

- Murder to Go had poison added to the seasoning mix for a spicy fast-food chicken dish. (It wasn't supposed to be a lethal dose, but that's not the most precise method of faking a mass foodborn-illness situation. The mastermind should consider himself lucky only one person died.)

King Spirits occasionally contain teratogens and banes. Thaw Beverages' soda potentiates any banes clinging to its drinkers. Dragon Valley Wines are carcinogenic, and its Pyrrus line of wines turns the drinker into a beacon for nearby banes and increases their vulnerability to possession.

- In Harvest Moon DS, you can do this at the Harvest Festival by adding a poisonous toadstool to the town's stew. Usually, doing this will result in the whole town falling ill (as well as making it taste like crap), but if you cultivate a level 99+ toadstool and add it to the stew, the game ends with your character eating the stew, choking, collapsing, and dying, with the same fate suggested to befall the rest of the town.

She can also slip an emetic poison into either the rival's lunch to make her sick and get her alone to murder her out of Senpai's sight, or into Senpai's lunch to make him sick and sabotage his budding relationship with the rival.
- Higurashi: When They Cry:
- Played with in the Onikakushi-ken arc.

- In the Strong Bad Email "techno", Strong Bad and The Cheat plot to break open a glow stick and pour the contents into Homestar's Mountain Dew.
Strong Bad: I hear they gotta pump your stomach if you drink that stuff...

- In the Strong Bad Email "techno", Strong Bad and The Cheat plot to break open a glow stick and pour the contents into Homestar's Mountain Dew.
- Looney Tunes and Merrie Melodies:
- "The Fair-Haired Hare": The objective of Yosemite Sam slipping poison into Bugs Bunny's carrot juice, so he – upset with a court order demanding they share the property – can own the jointly owned property outright.

- In Asterix and Cleopatra, Edifice frames the Gauls by sending a poisoned cake to Cleopatra in the Gaul's name, which is quickly detected as being poisoned. Strangely, the cake was made without eggs or flour—the only non-toxic ingredient in the entire recipe was orange juice (for flavoring).
- Hi Hi Puffy AmiYumi: Yumi's opponent in an Eating Contest sneaks into the arena the night before and dumps a bunch of iron horseshoes into her food to guarantee his victory.

- In one episode of Futurama, Nibbler starts annoying Bender. When asked to make a cake, he says menacingly "I'll make a cake you'll never forget...". He's shown grabbing rat poison...before putting it in front of a rat hole, stating "That'll get rid of all those damn rats."
- Invoked in the House of Mouse short "Mickey's Cabin", where Mickey is tied up by Pete and his cousin Zeka, who had just robbed an ATM.

- 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 them.
- In Russia, it is somewhat common for prostitutes to rob their johns in such a way. Their drug of choice for that is clonidine, an anti-hypertensic drug known there as clopheline — which in combination with alcohol reliably knocks even a large adult man out, and may even kill if they are not careful with the dose.
- The Roman Emperor Nero had a particularly devious twist on this: When he wanted to kill his stepbrother 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...
- During World War I, the British on the Middle East front would airdrop cigarette packs wrapped in British propaganda to the Turks. While the Turks laughed off the "surrender now" flyers, they really appreciated the cigarettes. On one occasion, a cigarette drop was made the day before the Brits were to attack a Turkish position. The cigarettes had been laced with opium, and the Turkish soldiers were too stoned to fight.
- In 1990, an employee at the Point Lepreau nuclear plant in New Brunswicknote poured some tritiated waternote in the staff's drinking water. Apparently he was trying to play a practical joke, by forcing people to give daily urine samples for an extended period. The joke didn't go over too well. In 2009, a "disgruntled employee" pulled the same stunt in the Kaiga nuclear plant in India. Must be something in the waternote .
- In World War II, food shortages in Germany meant that food waste was universally recycled as pigswill, including the leftovers from POW camps holding allied prisoners of war. Naturally, as soon as the inmates at Colditz Castle discovered this, they took to liberally seasoning their table scraps with shards of broken razor blades, despite the German authorities loudly threatening death to anyone they caught in the act.
- The modus operandi of Black Widow and Serial Killer Anjette Lyles. She killed two husbands, a mother-in-law, and her eldest child via first giving them food with high doses of arsenic-based poison, then slipping them more poison while taking care of them.
- 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 glycolnote . 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 policy.
- Oh, and antifreeze ending up mixed with food or drink is a dead giveaway of criminal intentions. It is also very easy to detect, and there is basically no possible innocent explanation, so using this method of poisoning is impractical anyway; it makes it very obvious that the victim was murdered, and the only realistic shot someone has at a defense is if there is someone else who could also have done it.
- "Aunt Thally" Caroline Grills went undected in her poisoning tea with Thalium of four family members until she tried to get another. She was part of a rash of women poisoners in 50s Sydney.
- Thallium was also used by one of the few serial poisoners in the late Soviet Union, Tamara Ivanyutina, and her family, who used Clerici solutionnote they obtained from an acquaintance under the guise of rat poison, to add too the food they later gave to everyone who (as they perceived) slighted them, or whose death might become a road to material wealth. Ivanyutina was slowly poisoning her husband, and already has poisoned his parents, while her elder sister was already an accompluished Black Widow at the point they were finally caught after several children and adults died in the school Ivanyutina was working as a dishwasher.
- Poisonous mushrooms of the Amanita genus (the most famous of which is Amanita phalloides or the Death Cap mushroom) are known for their good taste and innocent appearance concealing a deadly poison that will destroy your liver in a matter of hours. Thing is, it affects only the liver- that nausea and diarrhea you get six hours later isn't your GI tract trying to purge itself of the poison, but rather the first symptoms of acute liver failure. They've been used in assassinations for centuries, because they'll fool a food taster and the six hour latent period between administering the poison and the first symptoms appearing give the assassin plenty of time to slip out unnoticed. By the way, you can live for several days without a functioning liver, in great agony, until you finally succumb to ammonia poisoning.
This dish of mushrooms changed the destiny of Europe.—Voltaire, remarking on the death of Charles VI by mushroom poisoning.
- People who were (accidentally or deliberately) killed by Death Caps include the Roman Emperor Claudius, Charles VI of the Holy Roman Empire, Pope Clement VII, etc.
- In European courts in the Medieval and Early Modern periods, it was common to offer guests/hostages (the dividing line is often rather slim, Deadly Decadent Courts being what they are) boiled eggs and bone marrow, along with any other dishes, the idea being that since eggs and marrow are cooked in the shell/bone, they would be impossible to tamper with. Of course, eating the eggs and marrow is a grave insult, since it is an outright accusation that your host/captor is trying to poison you.
- In 1984 the Rajneesh cult attempted to take over the government of Wasco County, Oregon with a bioterror attack on its largest city, to make non-Rajneeshee voters get sick and stay home on election day, so the votes from Rajneeshpuram could carry the election. They sprayed Salmonella cultures onto the food in salad bars in 10 restaurants. The bioterrorists also spiked the water glasses of two county commissioners with Salmonella. Seven hundred fifty-one people were afflicted with gastroenteritis, and 45 of them were hospitalized. The plot failed when non-Rajneeshee voters rallied to the polls on election day.
- Exploiting the "randomly poisoned Halloween candy" urban legend mentioned above, Ronald O'Bryan killed his son in 1974 by putting poisoned Pixy Stix in his candy bag. For versimilitude, he also put the candy in the bags of his daughter and three other children trick-or-treating with them. Motive was collecting on the insurance policy he took out on his son. He was convicted and eventually executed.
