The Deadliest Snacks Ever Sold: From Contaminated Crackers To Toxic Candy

From a tortilla chip challenge that ended in a teenager’s death to peanut butter crackers tied to a massive Salmonella outbreak, some of America’s most recognizable snacks have been connected to devastating health consequences. Snacks are supposed to be convenient, inexpensive treats. But throughout history, certain products have become associated with food poisoning outbreaks, toxic ingredients, choking deaths and criminal investigations.

Some of these incidents involved manufacturing failures and contaminated ingredients. Others involved products deliberately designed to push the limits of what people could safely consume. In several cases, investigations resulted in nationwide recalls, criminal convictions and changes to food safety practices. From the Paqui One Chip Challenge and Diamond Shruumz mushroom chocolates to Kellogg’s Honey Smacks and contaminated fruit puree, here are some of the most dangerous snacks ever sold and the stories behind them.

1. Paqui One Chip Challenge

The Paqui One Chip Challenge became a viral internet sensation by daring people to eat an extremely spicy tortilla chip and withstand the heat for as long as possible. The chip was made with some of the world’s hottest peppers, including Carolina Reaper and Naga Viper peppers. It contained concentrated capsaicin, the compound responsible for the burning sensation associated with chili peppers.

The challenge attracted attention on social media, particularly among teenagers who filmed themselves eating the chip and recording their reactions. However, the product became associated with a tragedy in September 2023, when 14-year-old Harris Wolobah of Worcester, Massachusetts, died after participating in the challenge. An autopsy attributed his death to cardiopulmonary arrest following the ingestion of food containing a high concentration of capsaicin. The examination also identified an enlarged heart and a congenital heart condition called myocardial bridging, which may have increased his vulnerability.

Following his death and reports of other people becoming ill, Paqui voluntarily withdrew the product from store shelves and discontinued the challenge. The incident demonstrated that extremely concentrated chili pepper products can present serious health risks, particularly when consumed as part of an online dare.

2. Peanut Corporation Of America Peanut Butter Crackers

Peanut butter crackers are a familiar snack found in grocery stores, vending machines and lunchboxes. But in 2008 and 2009, peanut products contaminated with Salmonella triggered one of the most significant food safety scandals in American history. The outbreak was traced to products manufactured by Peanut Corporation of America (PCA), which supplied peanut ingredients to numerous food manufacturers. Contaminated peanut products were distributed nationwide and used in products including crackers, cookies and other packaged foods.

According to the Centers for Disease Control and Prevention, the outbreak sickened at least 714 people across 46 states. Nine deaths were ultimately associated with the outbreak. The investigation uncovered disturbing evidence of corporate misconduct. Federal prosecutors established that company officials had shipped peanut products despite positive Salmonella test results and falsified laboratory records to make products appear safe. In September 2014, PCA president Stewart Parnell was convicted of federal crimes related to the contaminated products. In 2015, he received a 28-year prison sentence, the longest criminal sentence imposed in a U.S. food safety case at the time. The scandal exposed serious weaknesses in food manufacturing oversight and demonstrated how contaminated ingredients could spread through an extensive supply chain.

3. Diamond Shruumz Mushroom Chocolate Bars

Chocolate bars are not typically associated with severe poisoning, but Diamond Shruumz products became the subject of a major federal health investigation in 2024. The company marketed its products as mushroom-infused treats, selling chocolate bars, gummies and infused cones. They were promoted as products containing proprietary mushroom blends, but laboratory testing raised serious questions about their ingredients.

The Food and Drug Administration (FDA) and CDC investigated reports of severe illnesses among people who consumed the products. The investigation identified 180 illnesses across 34 states, with 73 hospitalizations and three potentially associated deaths in the FDA’s final reported case count as of October 31, 2024. The CDC’s later summary reported two associated deaths, illustrating that death counts differed between the agencies’ reporting updates. Symptoms included seizures, confusion, loss of consciousness, abnormal heart rates, nausea and vomiting.

FDA testing identified several compounds in the products, including muscimol, a chemical found in certain mushrooms. The investigation also detected other substances, including compounds that were not clearly disclosed as ingredients. In June 2024, the manufacturer initiated a recall of all Diamond Shruumz chocolate bars, gummies and cones. The FDA warned consumers not to purchase or consume the products. The incident raised concerns about the safety and regulation of commercially marketed mushroom-infused edibles.

4. Pixy Stix And The Halloween Candy Murder

Pixy Stix are known for their brightly colored packaging and sweet powdered candy. However, the product became associated with one of America’s most notorious Halloween murder cases. In 1974, Ronald Clark O’Bryan, a Texas man known as the Candy Man, poisoned his 8-year-old son, Timothy, using potassium cyanide placed inside a Pixy Stix candy container.

O’Bryan distributed other poisoned candy containers to children while trick-or-treating in Deer Park, Texas. His son consumed the poisoned candy and became critically ill before dying. Investigators discovered cyanide in the child’s body. The investigation eventually revealed that O’Bryan had purchased the poison and had taken out life insurance policies on his children. Prosecutors established that he had planned the killing as part of an insurance fraud scheme.

O’Bryan was convicted of capital murder and executed in 1984. It is important to distinguish this case from a contaminated candy outbreak. Pixy Stix were not manufactured with cyanide. The candy was deliberately poisoned by an individual who used its packaging to conceal a murder.

5. Kinder Surprise Eggs

Kinder Surprise eggs combine chocolate with a small plastic capsule containing a toy. Although the product is popular internationally, its design has raised safety concerns involving young children. The concern is not the chocolate itself. It is the small toy capsule and its contents, which can become choking hazards if swallowed.

The FDA has long restricted Kinder Surprise eggs in the United States because federal law prohibits confectionery products containing embedded non-nutritive objects that could create a choking risk. The agency’s import alert specifically identifies Kinder Surprise eggs as an example of products containing objects that consumers could unknowingly choke on. The danger is particularly significant for young children, who may not understand that the plastic capsule and toy are not edible. The product should not be confused with Kinder Joy, which separates the chocolate and toy into different compartments rather than embedding the toy inside the chocolate.

6. Konjac Mini Fruit Jelly Cups

Small fruit-flavored jelly cups have caused serious choking incidents, particularly among young children and older adults. Some of these products contain konjac, also known as konnyaku or glucomannan, an ingredient derived from a plant. Unlike conventional gelatin desserts, certain konjac jelly products maintain a firm consistency and do not easily dissolve in the mouth. Their small, slippery shape can make them difficult to swallow safely.

In 2001, the FDA issued warnings about imported konjac jelly cups after reports of choking deaths and near-fatal incidents. The agency reported that three children had died from choking on konjac jelly candy in the United States. The products were commonly packaged in small plastic cups resembling individual servings of gelatin dessert. Some contained pieces of preserved fruit. The FDA subsequently established restrictions on these products because of their physical characteristics and the danger they presented. This is an important example of how a snack can become dangerous because of its texture, shape and packaging rather than a toxic ingredient.

7. WanaBana Apple Cinnamon Fruit Puree

A snack marketed toward babies and young children became the center of a major contamination investigation in 2023. WanaBana apple cinnamon fruit puree pouches were recalled after investigators discovered dangerously elevated levels of lead in the products. The investigation began after North Carolina health officials identified children with elevated blood lead levels. Authorities identified the apple cinnamon puree as a potential common source of exposure. The FDA subsequently confirmed elevated lead concentrations in product samples and worked with state officials to investigate the contamination. The recall eventually expanded beyond WanaBana to include certain cinnamon applesauce products sold under the Schnucks and Weis brands.

The FDA reported 34 illness reports potentially linked to the recalled products as of November 16, 2023. Lead exposure can cause serious health problems, particularly in young children, whose developing brains and nervous systems are especially vulnerable. Potential symptoms of lead exposure include abdominal pain, vomiting, anemia, fatigue and neurological problems. Children may not show obvious symptoms immediately. FDA testing found 2.18 parts per million of lead in one WanaBana product sample collected from a Dollar Tree store. That concentration was more than 200 times the agency’s proposed draft action level for fruit purees intended for babies and young children. The incident demonstrated that even products marketed as convenient fruit snacks can present serious health risks when manufacturing or ingredient contamination goes undetected.

8. Frito-Lay WOW Chips

In the late 1990s, Frito-Lay introduced WOW! chips, a line of snack foods made with Olestra, a fat substitute designed to deliver the taste of traditional potato chips without the calories from conventional fat. The ingredient became controversial because of its digestive effects. Olestra is not absorbed by the body in the same way as ordinary dietary fat. Instead, it passes through the digestive system largely unchanged.

For some consumers, eating products containing Olestra caused gastrointestinal problems, including diarrhea, abdominal cramps and loose stools. The ingredient became widely associated with the phrase “anal leakage.” The FDA approved Olestra for use in certain savory snacks in 1996, subject to labeling requirements that included a warning about possible gastrointestinal effects and reduced absorption of certain vitamins.

The products were eventually marketed under different names, including Lay’s Light, Ruffles Light and Doritos Light. Research published in medical literature found that larger amounts of Olestra were more likely to produce gastrointestinal symptoms. However, researchers did not find evidence that it caused permanent pathological changes to normal gastrointestinal function. Despite the attention surrounding the side effects, the products were not responsible for a documented deadly outbreak. Their place on this list comes from the unusual and unpleasant reactions associated with the ingredient.

9. Kellogg’s Honey Smacks

Honey Smacks became the subject of a nationwide food poisoning investigation in 2018 after health officials linked the cereal to a Salmonella outbreak. The sweetened puffed wheat cereal was recalled after investigators identified it as the likely source of infections involving Salmonella Mbandaka.

According to the CDC’s final investigation, 135 people became sick across 36 states, and 34 were hospitalized. No deaths were reported. The outbreak affected people ranging from infants to older adults. Salmonella infections can cause diarrhea, fever and abdominal cramps. Symptoms generally begin between 12 and 72 hours after consuming contaminated food, although illness can sometimes become severe.

The investigation involved the CDC, FDA and state health departments. Epidemiological evidence indicated that people who became sick were more likely to have eaten Honey Smacks than other cereals. Kellogg recalled the cereal in June 2018. The CDC continued warning consumers because the product had a long shelf life and could remain in kitchen cupboards long after the recall began. The outbreak illustrated how contamination at a manufacturing facility can turn an everyday breakfast food into a nationwide public health concern.

10. Hot Pockets

Hot Pockets are popular microwaveable sandwiches, but certain products were recalled in January 2021 after concerns that they could contain pieces of glass and hard plastic. Nestlé USA announced a voluntary recall of select batches of its Garlic Buttery Crust Pepperoni Pizza Hot Pockets sold in 12-count value packs.

The company warned that consuming the affected products could cause choking or injuries to the mouth and digestive tract. The recall involved four specific batch codes with a best-before date of February 2022. It did not apply to every Hot Pockets product or flavor. The company reported receiving a complaint involving a potential injury associated with consumption of the affected product. The incident demonstrated that physical contamination can create serious risks even when a product does not contain harmful bacteria or chemicals. Consumers were advised not to eat the affected products and to follow the recall instructions.

11. Toxic Waste Nuclear Sludge Candy

Toxic Waste Nuclear Sludge candy was recalled in 2011 after testing identified elevated levels of lead in certain products. The sour candy was imported from Pakistan and sold in small individual pieces. The Georgia Department of Agriculture announced that Candy Dynamics, the company associated with the product, was recalling all flavors of the 0.3-ounce Nuclear Sludge candy after testing found elevated lead concentrations.

The recall followed an earlier recall involving larger 0.7-ounce products. Testing identified lead concentrations ranging from 0.101 to 0.311 parts per million in certain smaller products. At the time, the FDA’s recommended maximum level for lead in candy likely to be consumed frequently by small children was 0.1 parts per million. Lead is a toxic heavy metal that can accumulate in the body. Children are particularly vulnerable because exposure can affect brain development, learning and behavior.

The recall was intended to prevent further exposure, particularly among children who might consume the candy regularly. There is no verified evidence that the recalled Nuclear Sludge products caused deaths. The documented concern was elevated lead contamination and the potential health consequences of repeated exposure.

12. Cadbury Dairy Milk Chocolate

Even internationally recognized chocolate brands have faced food safety problems. In 2006, certain Cadbury Dairy Milk products manufactured in Britain were recalled after concerns that they could be contaminated with Salmonella. The Canadian Food Inspection Agency issued a health hazard alert covering several imported Cadbury products, including different varieties of Dairy Milk chocolate.

The recall followed an announcement by Cadbury after contamination concerns were identified. Salmonella is a bacteria that can cause foodborne illness, with symptoms including fever, diarrhea, nausea, vomiting and abdominal pain. The risk is particularly serious for young children, older adults and people with weakened immune systems. Canadian authorities warned consumers not to eat the affected products and worked with importers to remove them from stores.

Importantly, the Canadian alert reported no illnesses associated with the recalled products at the time. This was a precautionary recall rather than a confirmed deadly chocolate outbreak. The incident demonstrated that even established international food brands must maintain strict manufacturing and contamination controls.

Why These Snacks Became So Dangerous

The stories behind these products reveal several different types of food safety failures and consumer risks. Some involved deliberate criminal activity, while others resulted from contaminated ingredients, inadequate manufacturing controls or product designs that created choking hazards. It is also important to distinguish between products that caused documented deaths and those that were recalled because of potential health risks. Not every product on this list caused a fatality.

The Peanut Corporation of America scandal, for example, involved a confirmed multistate Salmonella outbreak and criminal convictions. The Paqui One Chip Challenge was associated with a teenager’s death, while Diamond Shruumz products were connected to multiple hospitalizations and potentially associated deaths. Other products, including WOW! chips, Toxic Waste Nuclear Sludge and Hot Pockets, became controversial because of gastrointestinal reactions, contamination or physical injury risks rather than documented deaths. These incidents demonstrate why food safety inspections, ingredient testing, accurate labeling and effective recall systems matter.
