    "description": "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.\n",

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.\n",

  "caveats": "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.\n",
