    "description": "Most readers who meet this question in a US or European context quietly assume the answer is \"basically zero\" — the same intuition that drives the US-specific food-poisoning entry. The global framing sits in an awkward place: Western readers tend to overestimate their own country's outbreak-driven risk (salad recalls, fast-food E. coli clusters) while systematically underestimating the burden of diarrheal foodborne illness in low- and middle-income countries. We have not found a cross-national survey that isolates \"fear of dying from contaminated food\" as a clean question, so the perceived side here is editorial intuition, not polled data.\n",

Divided by a global population of ~8 billion gives an annual rate of ~5.25 per 100,000, roughly six times the US per-capita foodborne mortality rate. Compounded over 60 adult life-years: 1 − (1 − 5.25e-5)^60 ≈ 3.15e-3, or about 1 in 320 global lifetime. The uncertainty band below is dominated by the FERG 95% UI on the death estimate (310K–600K) rather than sampling noise in the population denominator. This is a global-average scale marker and is useless as a personal estimate — see the regional_breakdown and the body text for why the Sub-Saharan Africa and high-income-country figures differ by more than an order of magnitude.\n",

The global average is a scale marker, not a personal estimate: regional per-capita risk varies by roughly 37x across WHO subregions, and within LMICs mortality is overwhelmingly concentrated in children under 5 rather than adults. A healthy adult in a high-income country has a per-year risk well below the global average; an infant in a rural LMIC has a risk many times above it. Excludes allergic reactions, deliberate poisoning, and gastrointestinal infections transmitted by water or person-to-person rather than food.\n",
