california state law forcing every baby food maker selling in CA to publish lab results for arsenic, cadmium, lead, and mercury for every lot. effective jan 2025. 47,802 measurements across 828 products from 31 brands.
california's AB 899 is the most ambitious heavy-metal disclosure law in the world. signed in 2023 and effective january 2025, it forces every baby food maker selling in california to publish lab results for arsenic, cadmium, lead, and mercury. every lot. every product. uploaded as PDFs to the manufacturer's own website with QR codes on the package.
i scraped the entire corpus in 50 minutes one weekend in april 2026. that pull is what powers this slice of the database, 47,802 individual measurements covering 828 unique baby food products from 31 brands, with most products tested for all four metals across multiple lots. the AB 899 reanalysis page at /pages/babyfood goes deeper on the dose-band scoring and worst-offender brand lists. there is also a separate writeup of the scrape itself at /pages/lead-database-extraction-story.
the law forces every test, even the failing ones, to be public. that's the part that matters. before AB 899 you could test a lot, fail it, throw it out, and never tell anyone. now you have to publish it.
AB 899 contributed measurements to 1 of the 13 categories in the lead database. each card links to the full sortable table for that category, where you can filter by source = "AB 899" to see only these rows.
metals tested: arsenic, cadmium, lead, mercury.
units: normalized to ppb (parts per billion by mass), identical to µg/kg. 1,000 ppb = 1 ppm = 1 mg/kg = 0.0001%. recall records (where the original notice did not publish a concentration) are flagged in the table as "recall record" rather than a number.
license: public disclosure (state of california). when you reuse rows from this source, attribute the original source. the unified database itself is published under CC-BY-SA 4.0.

the lead database hub stitches together AB 899 with eight other open-license sources for a unified, searchable view of consumer-product heavy-metal data. nine sources, thirteen categories, 67,497 measurements, all normalized to the same units.
