Poisoned candy myths

[4][5] 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.

In the 1890s and 1900s, the US Bureau of Chemistry, in conjunction with state agencies, tested hundreds of kinds of candy and found no evidence of poisons or adulteration.

[7] 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.

[6] The prevalence and persistence of these myths during the 1960s and 1970s, a time of social upheaval, greater racial integration, and improved status for women, reflected societal questions about who was trustworthy.

[8] Because society was struggling with questions about whether to trust neighbors in newly integrated neighborhoods, or young women who were publicly rejecting the subservient, motherhood-focused roles previously assigned to women, these stories about unidentifiable neighbors allegedly harming random, innocent children during an event intended to bring happiness to these children caught and retained the public imagination in a way that accurate stories about a judgmental neighbor, an abusive parent, or an adult carelessly leaving harmful chemicals where children can reach them, would not have.

[8] An academic view sees this as an example of a rumor panic, with Halloween developing as a carnival-like folk institution – meant to release social tensions – losing its functionality as neighborhoods themselves break down (for various reasons).

[10] This story also promoted the sale of individually wrapped, brand-name candies and discouraged people from giving homemade treats to children.

[8] In 1964, a disgruntled Long Island, New York woman gave out packages of inedible objects to children who she believed were too old to be trick-or-treating.

The packages contained items such as steel wool, dog biscuits, and ant buttons (which were clearly labeled with the word "poison").

This article claimed that "Those Halloween goodies that children collect this weekend on their rounds of 'trick or treating' may bring them more horror than happiness" and provided specific examples of potential tampering.

[1][17] Best found five child deaths that were initially thought by local authorities to be caused by homicidal strangers, but none of those were sustained by investigation.

This one-sided coverage contributed to the overall panic and caused rival media outlets to issue reports of candy tampering as well.

Apples and homemade treats were common gifts to trick-or-treating children in the earlier parts of 20th century. Over time, parents preferred individually wrapped, store-bought candy.
Candies such as candy corn were regularly sold in bulk during the 19th century. Later, parents thought that pre-packaged foods were more sanitary.
