State Food Ingredient Regulations
10 US states have enacted food-additive bans or regulations, sorted by the number of regulated ingredients. State data is compiled from enacted statutes — beginning with California's Food Safety Act (AB 418, 2023) — and tracked legislation in New York, Illinois, and other states; see our methodology.
Navigating PlainIngredients by State
The state index is the best place to start if your question is geographic ("Which state leads in X?", "What does this look like in my state?"). Each state page drills down into the full set of records for that jurisdiction, along with summary statistics and comparisons across the country. Data coverage can vary by state — some states publish richer underlying datasets, some refresh more often, and a small number of states lag the national median. We flag coverage gaps on the state page itself.
State-Level Data Quality
Because each state operates its own reporting pipeline, subtle format differences show up across the dataset. We normalize obvious discrepancies — title casing, leading zeros on zip codes, abbreviation expansions — without altering the underlying data. When two states use incompatible category codes for the same real-world concept, we map them to a common taxonomy and document the mapping on the methodology page. Where a mapping is imperfect, we leave the original category visible on the record.
Interpreting State Comparisons
Raw totals by state can be misleading if you do not account for population. Whenever we present a count-based ranking, we also publish a per-capita variant when meaningful. Per-capita comparisons should be read with care in small states and sparsely populated states: the denominator is small, so one or two records can swing the rate substantially. For consequential comparisons, always click through to the state page and look at the underlying count, the time frame, and the methodology note before concluding that a difference is real.
When State Data Disagrees With Federal Data
Occasionally the state-level number you see on PlainIngredients will differ from a federal aggregate. This is usually because the state reported its data on a different cadence, used a slightly different population, or applied a narrower definition of the measured concept. We cite the exact state dataset on the state page; if you need to reconcile with a federal source, the methodology page links both and explains the differences. We do not silently "correct" state data to match federal data or vice versa.
