Poisoned candy myths

Poisoned candy myths are urban legends about malevolent strangers hiding poisons or sharp objects such as razor blades, needles, or broken glass in candy and distributing the candy in order to harm random children, especially during Halloween trick-or-treating. These stories serve as modern cautionary tales to children and parents. These stories repeat two themes that are common in urban legends: danger to children and contamination of food.

No cases of strangers killing or permanently injuring children this way have been proven. Commonly, the story appears in the media when a young child dies suddenly after Halloween. Medical investigations into the actual cause of death have always shown that these children did not die from eating candy given to them by strangers. However, in rare cases, adult family members have spread this story in an effort to cover up murder or accidental deaths. In other incidents, a child who has been told about poisoned candy places a dangerous object or substance in a pile of candy and pretends that it was the work of a stranger. This behavior is called the copycat effect.

Folklorists, scholars, and law enforcement experts say that these stories have been "thoroughly debunked".

Claims that candy was poisoned or adulterated gained general credence during the Industrial Revolution, when food production moved out of the home or local area, where it was made in familiar ways by known and trusted people, to strangers using unknown ingredients and unfamiliar machines and processes. Some doctors publicly claimed that they were treating children poisoned by candy every day. If a child became ill, and had eaten candy, the candy was widely assumed to be the cause. However, no cases of illness or death were ever substantiated.

In the 1890s and 1900s, tests by the US Bureau of Chemistry and other state agencies on hundreds of kinds of candy found no evidence of poisons or adulteration. These tests revealed that inexpensive glucose (from corn syrup) was in common use for cheap candies, that some candies contained trace amounts of copper from uncoated copper cooking pans, and that coal tar dyes were being used for coloring, but there was no evidence of the many types of poison, industrial waste, garbage, or other adulterants alleged to be present. Eventually, the claims that children were being sickened by candy were put down to indigestion due to overeating, or to other causes, including food poisoning due to improper cooking, hygiene, or storage of meat and other foods.
