Perceived
The "bee in the soda can" scenario is one of the more vivid and widely circulated outdoor hazard stories. Social media amplifies occasional case reports of people who swallowed an insect, felt a sting in the throat, and required emergency treatment, which inflates the perceived frequency considerably relative to the actual rate. Most people who have spent summers drinking outdoors overestimate how often this ends badly.

~11,000 estimated oropharyngeal (mouth/throat) sting emergency visits per year, United States

Show derivation
Huff, Phillips, and Keith (Wilderness & Environmental Medicine, 2025) used NEISS data (2004–2023) and estimated that approximately 5% of all Hymenoptera sting emergency department visits involve the oropharyngeal (mouth and throat) region, typically from insects swallowed with food or drink. Applying that 5% fraction to the widely cited ~220,000 annual US ED visits for all Hymenoptera sting reactions yields ~11,000 oropharyngeal sting visits per year. Annual probability: 11,000 / 335,000,000 ≈ 3.3 × 10^-5. Compounded over 59 years of remaining adult life: 1 - (1 - 3.3e-5)^59 ≈ 0.0019. The estimate is intentionally conservative because "oropharyngeal sting" is broader than the specific can/bottle-drinking scenario, but the NEISS study is the only US surveillance source that approximates this route.

The mechanism here is not mechanical choking — bees and wasps are too small to obstruct the airway as a physical object. The danger is the sting itself: inside the mouth or throat it causes localized inflammatory edema that can narrow the airway even in non-allergic individuals, and in those with venom allergy it can trigger full systemic anaphylaxis. The ~11,000/year figure is an extrapolation from a 2025 NEISS study that found ~5% of all sting ED visits are oropharyngeal; it is not a direct count of "swallowed insect while drinking" and may include other routes of oral sting (e.g., eating). Deaths from specifically swallowed insects are not separately tracked.

A bee or wasp inside a can or bottle is a genuine, if rare, hazard — and the mechanism is less obvious than most people assume. The danger is not that the insect physically blocks your airway; bees and wasps are small enough to swallow without obstruction. The danger is the sting: delivered inside the mouth, posterior pharynx, or esophagus, it triggers localized inflammatory edema in confined anatomy where even modest swelling can produce stridor, difficulty swallowing, and in severe cases airway compromise — even in people with no prior venom allergy. In those who do have venom allergy (roughly 3% of US adults), an oropharyngeal sting can trigger full systemic anaphylaxis.
A 2025 NEISS analysis by Huff, Phillips, and Keith estimated that approximately 5% of all Hymenoptera sting emergency visits involve the oropharyngeal region, typically from insects accidentally swallowed with food or drink. Applied to the ~220,000 annual US sting ED visits, that implies around 11,000 oropharyngeal sting ER trips per year — not a trivial number in absolute terms, but spread over 335 million people and 59 remaining adult years, it comes to roughly 1 in 500 over a lifetime. Only about 2% of those cases required hospitalization. Deaths from this specific route are not separately tracked in US surveillance; they are absorbed into the ICD-10 X23 “sting” category that averages ~72 per year from all mechanisms combined.
The fear is real but the framing matters: the scenario to worry about is not “the insect itself gets stuck” but “the sting triggers swelling or anaphylaxis in a place the body finds very hard to manage.” Practical risk reduction is simple — check the opening of outdoor cans and bottles before drinking, pour into a clear glass, or use a cup with a lid. These are low-friction habits that effectively eliminate the exposure route without any change to outdoor behavior otherwise.

Oropharyngeal Stings by Stinging Insects Presenting to U.S. Emergency Departments- Statistic
Approximately 5% of all Hymenoptera sting ED visits involve the oropharyngeal region; ~2% of oropharyngeal sting patients required hospitalization- Excerpt
“[Paraphrase from abstract — full text paywalled] Huff, Phillips, and Keith analyzed NEISS data (2004–2023) for Hymenoptera stings in the oropharyngeal region (mouth and throat), typically from insects accidentally swallowed with food or drink. Oropharyngeal stings accounted for approximately 5% of all sting ED visits; roughly 2% of those patients required hospitalization. ”

Toxicological Risk Assessment of Accidental Ingestion of Bees and Wasps- Statistic
The actual number of accidental bee/wasp ingestion incidents remains unknown; deaths from ingestion are not separately coded in any US or EU surveillance system- Excerpt
“[Paraphrase from open-access PMC article] The authors review the toxicological risk of accidental bee and wasp ingestion, noting that oropharyngeal edema and anaphylaxis from internal stinging are the primary injury mechanisms. They state that the actual number of accidental ingestion incidents remains unknown, as fatalities from this route are subsumed under ICD-10 code X23 (Contact with hornets, wasps and bees) without route sub-classification. ”

- Confirms the surveillance gap: no dedicated count exists for deaths or ER visits specifically from swallowed insects. Used to justify the wide uncertainty band and to establish that the Huff 2025 oropharyngeal fraction is the best available approximation.
