Halloween candy tampering has fueled frightening headlines for decades, but cases of strangers deliberately poisoning or contaminating treats collected by trick-or-treaters are exceedingly rare. Food allergies, choking hazards and foodborne illness are more common concerns for families celebrating Halloween.
Here are some precautions to help keep children and party guests safe.
Trick-or-treating
The U.S. Food and Drug Administration recommends that parents wait until children get home before inspecting their Halloween candy.
- Check the wrappers: Look for tears, pinholes, discoloration or other signs of damage or tampering. Throw away anything suspicious.
- Be cautious with homemade treats: Avoid items without ingredient labels, particularly those received from people the family does not know.
- Watch for allergens: Read labels carefully and keep treats containing ingredients that could trigger a child's food allergy out of their bag.
- Think about choking hazards: For very young children, remove hard candies, gum, small toys and other items that could cause choking.
- Wash up: Have children wash their hands before eating their treats.
- Feed them first: A meal or snack before trick-or-treating can help discourage children from sampling candy along the way.
Families looking for allergy-friendly Halloween options can participate in the Teal Pumpkin Project, an initiative from Food Allergy Research & Education (FARE). Participating households offer non-food treats, such as stickers, glow sticks, pencils or small toys, for children who cannot safely eat some or all Halloween candy. A teal pumpkin displayed outside signals that non-food treats are available. More information is available on FARE's Teal Pumpkin Project website.
Candy scares and the facts
The fear of strangers poisoning Halloween candy is largely overblown.
Sociologist Joel Best of the University of Delaware has studied reports of Halloween candy tampering for decades. His research has found no verified cases of a child being killed or seriously injured by a stranger who deliberately contaminated a treat collected during trick-or-treating. Many reports have involved hoaxes, accidents or misattributed causes.
That does not mean parents should ignore suspicious candy. Discard anything that appears tampered with and report credible concerns to law enforcement. But the familiar image of strangers lurking with poisoned treats is not supported by the evidence.
One notorious case occurred in Texas in 1974, when 8-year-old Timothy O'Bryan died after eating a cyanide-laced Giant Pixy Stix on Halloween night. His father, Ronald Clark O'Bryan, was convicted of murder in a scheme motivated by life-insurance money and was executed in 1984. He had also distributed poisoned candy to other children, but none of them ate it.
The case helped fuel fears about poisoned Halloween candy. But the killer was Timothy's own father, not a stranger targeting trick-or-treaters.
The history of product tampering also includes the 1982 cyanide murders involving Tylenol capsules in the Chicago area. Those killings led to federal action on tamper-resistant packaging and helped spur Congress to pass the Federal Anti-Tampering Act in 1983. The law addressed consumer-product tampering broadly, not Halloween candy specifically.
Food safety at Halloween parties
The same food safety rules that apply throughout the year apply at Halloween parties, too.
- Choose pasteurized cider and other beverages: Unpasteurized apple cider and other juices can contain harmful bacteria. Serve pasteurized products, particularly to children and others at increased risk of serious illness.
- Keep cold foods cold: Sandwiches, cheese platters, salads and cream-based desserts should not sit at room temperature for more than two hours, or one hour when temperatures exceed 90 degrees Fahrenheit.
- Don't taste the raw batter: Uncooked flour and eggs can carry harmful bacteria, including E. coli and Salmonella. Wait until cookies and other baked goods are fully cooked.
- Check cooking temperatures: Use a food thermometer to make sure foods reach safe internal temperatures. Keep hot foods hot and cold foods cold.
- Keep raw foods separate: Wash hands, utensils and preparation surfaces. Keep raw meat, poultry and seafood away from ready-to-eat foods, and rinse fresh produce under running water.
- Plan for food allergies: Ask guests about allergies, check ingredient labels and keep foods containing allergens separate from other dishes.
Planning an apple-bobbing game? Wash the apples thoroughly first. You can also choose an alternative that does not require participants to put their mouths into shared water.
Protecting pets
Halloween candy can be dangerous for pets. Chocolate contains theobromine and caffeine, which are toxic to dogs and cats. Dark and baking chocolate generally pose greater risks than milk chocolate. The danger depends on the amount eaten and the animal's size.
Sugar-free candy and gum may contain xylitol, which can cause a rapid drop in blood sugar and potentially fatal liver damage in dogs.
Keep candy bowls and treat bags out of pets' reach. If a pet eats chocolate, xylitol or another potentially toxic food, contact a veterinarian or animal poison control service immediately. The ASPCA Animal Poison Control Center can be reached at 888-426-4435.
