GB 31650-2019 MRL × FDA ADE：甲砜霉素（Thiamphenicol）
Cross-reference between China's veterinary-drug residue limit standard (GB 31650-2019, 食品中兽药最大残留限量) and the US FDA CVM adverse-event (ADE) report database (openFDA animalandveterinary/event.json). This is a structural link, not a clinical assertion.

Honest scope note
GB 31650-2019 is a food (residue-limit) standard, not a feed-additive standard — it governs residues in animal-derived *food* (meat, liver, kidney, fat, milk, egg). Its pet-food relevance is indirect: animal-origin pet-food ingredients (meat meal, poultry by-product, fish, egg, dairy) must comply. The ADE count reflects US spontaneous-reporting volume, not incidence or per-animal risk, and may not include China-specific products or trade names. Active-ingredient→OpenFDA term mapping is editorial; a 0 or low count may reflect openFDA ingredient naming rather than true absence of reports.
