** ''Series/DenshiSentaiDenziman'': A hamburger-themed monster sells "ham[[UsefulNotes/{{baka}} baka]]s" which cause children that eat it to lose the ability to see colors, only want to eat more hambakas, and be driven to commit acts of vandalism. A toothbrush monster in another episode puts on a strong man show and gives the audience free cotton candy which is infested with cavity-causing bacteria and then takes over a dentist's office so they can rip out the children's teeth when they come to get the cavities fixed, all because [[EvilIsPetty Queen Hedrian can't stand anybody having prettier teeth than her]]. In another episode, the villains trick two boys into selling beetles that are actually bombs produced by a monster disguised as a tree stump so that rumors of exploding beetles will cause a panic in order to trick people having the forests bulldozed to get rid of the beetles and thus starve everyone of oxygen.

** ''Series/BattleFeverJ'': What is probably the funniest episode of the show had an egg monster who transforms into a rooster that lays golden eggs which grant the wishes of the people that eat them, at the cost of causing them to ignore their responsibilities. Another episode had a snail-themed monster giving out escargot which is served with poisoned forks to try to force children who are picky eaters to join Egos.

* ''VideoGame/SunsetOverdrive'' has Overcharge energy drink, which, after a massive party to celebrate its launch, was revealed to [[MutagenicFood cause mutations into horrific monsters]]. Floyd, who worked on the development of the drink, mentions that it was an accident that the mutagenic drinks were made available, but with all the cover-ups [=FizzCo=] uses to hide the catastrophe (including killer robots, a force field keeping anyone from leaving the city, and a giant balloon of their mascot armed with loads of weapons, it is obvious it wasn't as accidental as it seems. [[spoiler: The ending pretty much confirms this, as it [[SequelHook shows several large containers of Overcharge being shipped to other countries]] despite [=FizzCo=] being fully aware of its effects]].

* In the ''Series/StarTrekTheNextGeneration'' episode "[[Recap/StarTrekTheNextGenerationS5E6TheGame The Game]]", an alien race plans to take over the Federation with a video game that [[ElectricInstantGratification directly stimulates the pleasure center of the brain]], starting (naturally) with the crew of the ''Enterprise'', save for [[CreatorsPet Wesley]] [[spoiler:and Data, who lacks a pleasure center]].

* Any consumable product made from [[GreenRocks ghost rock]] in ''TabletopGame/{{Deadlands}}'' contains evil, and most of them have some nasty random side effects.
* The introductory story for ''TabletopGame/{{Shadowrun}} 4th Edition'' subverts this. The Shadowrunner team is hired by a corp to put something nasty in a rival corp's soda in order to make it taste bad. The runners find out that the substance in question would have led to the mass poisoning of many of the orks and trolls it was supposed to be marketed to, and the culprit is their employer's human assistant, who it turns out is part of the human-supremacist hate group Humanis, who engineered this scheme to ruin the reps of both his boss and the group's fixer.
* The ethos of the Pentex Corporation from ''TabletopGame/WerewolfTheApocalypse'' went something like this: cram products full of corrupted spirits that serve [[GodOfEvil a divine embodiment of entropy and suffering]]; work towards encouraging a general [[CrapsackWorld crapsack atmosphere]], so that your customers can act as receptive hosts; watch as the possessed customers mutate and degrade into hideous monsters; claim profits and soldiers.
** There also was an entire source book about Pentex and its subsidiaries which explored the multitude of themes possible. It also noted that the rather heavy-handed approach described above was once taken by a Pentex-owned computer hardware corporation. What do you get when you plunk a spirit of entropy and destruction into every piece of hardware you sell? Yup, a product that is entirely unreliable and won't be bought, thus entirely undermining the purpose of the whole thing. When the Pentex Board of Directors learned of this, they were... [[PragmaticVillainy disappointed]]. The CEO's successor takes a more moderate approach, using it primarily to supply the other branches of Pentex with cheap computers - and of course selling a few outdated and mildly tainted models to schools.

* In ''The Transformation'' from Marilyn Kaye's YA ''Literature/{{Replica}}'' series, teenagers' strange behavior turns out to be caused not by the candy fad or the hypnosis fad, but by subliminal messages in the television show everyone's watching.
