Who is behind Food Dye Laws

Food Dye Laws is published by Radif Partners, a company that builds free reference tools on public rules. This one exists because the question "is this dye banned?" now has a different answer in each state, for each kind of food and for each date, while the FDA, the legislatures and the courts each publish only their own part. We read those texts and put them side by side.

What the site does

The state checker combines the FDA rule and every state law for any dye or additive on any date. The ingredient checker reads a label's list. The product search shows what labels filed with USDA say, category by category, with their dates. The timeline puts every federal and state date in order. Each tracked substance, each state with a law of its own and each food category has a page.

Where the facts come from

Federal decisions from the Federal Register and the electronic Code of Federal Regulations; state laws from each legislature's site or the state code; court orders from the court record where we could open it; product data from USDA FoodData Central. Every fact carries its source and the date we read it. When an official source could not be read, the site says "not confirmed". The method page describes the checks.

What we are not

We are not the FDA, a state agency, a legislature or a law firm, and we work for no food, color or ingredient company. We give no legal advice and no health advice: where an agency has taken a position on safety, we quote it and name it.

How the site is paid for

Nothing is sold here and there is no affiliate link. If advertising is added one day, it will never sit inside a tool, and it cannot use what you type, which never leaves your browser.

Tell us when something is wrong

Laws change, courts rule and FDA orders get stayed. If a fact differs from the official text, write to contact@fooddyelaws.com with the page. The editorial policy explains how a correction is made and dated. The site has 53 pages of tools and guides.
