Quick Answer: In April 2025, the FDA announced a voluntary plan to remove six petroleum-based synthetic dyes from the US food supply, targeting end of 2026 [1]. Major manufacturers including Tyson Foods, Nestle USA, and General Mills have committed to reformulate by 2027 or sooner [4]. Health Canada has not issued an equivalent directive. These dyes remain legally permitted in Canadian food products as of this writing [6].

The six dyes are Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2, and Green No. 3. You've eaten them. They show up in breakfast cereals, sports drinks, candy, flavoured chips, mac and cheese, and dozens of other products that fill a standard grocery cart.
This spring, the US started the process of removing them. Canada hasn't followed. And the difference between a "US formula" and a "Canadian formula" matters more than most people realize.
Here's what actually happened, which brands are changing, and what you can do right now at the store.
What Are the Six Dyes Being Phased Out?
Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2, Green No. 3. All six are petroleum-derived colorants. They serve no nutritional function. Their only job is to make food look more vivid than it actually is [1][2].
A seventh dye, Red No. 3 (also called Erythrosine), was handled separately. The FDA revoked it in January 2025 under the Delaney Clause, a law that prohibits food additives shown to cause cancer in animals [5]. That revocation takes effect for food and beverages on January 15, 2027. The six-dye phase-out is a different process with a different legal basis [5].
The distinction matters because the six-dye plan is voluntary, while Red No. 3's removal is a mandatory legal revocation. One is an industry commitment; the other is a law that companies must follow.
How Did the Phase-Out Come About?
On April 22, 2025, HHS Secretary Robert F. Kennedy Jr. and FDA Commissioner Marty Makary announced that the FDA would work with food manufacturers to phase out petroleum-based synthetic dyes by end of 2026 [1][2][3]. The announcement used the language of an "understanding" with industry, not a formal rule.
Legal analysts flagged the gap right away [2]. No binding regulation accompanied the announcement. The mechanism is cooperative: the FDA and HHS signalled support for reformulation, and food companies agreed to move in that direction, but there was no enforcement mechanism attached.
In the months that followed, the Consumer Brands Association, which represents many major food manufacturers, adopted December 31, 2027 as the industry's working target, one year past the original FDA window [9].
That's where things stand now. The phase-out is real, the commitments are on record, and the timeline has shifted from end-of-2026 to end-of-2027 for most of the industry.
Which Brands Have Actually Committed to Reformulating?
Six major manufacturers made public commitments following the announcement [4]:
Tyson Foods moved first. The company completed removal of synthetic colors from its product lines by May 2025, ahead of any official deadline [4].
Nestle USA committed to eliminate all FD&C synthetic dyes from its US portfolio by mid-2026 [10].
Kraft Heinz reported that 90% of its products were already synthetic-dye-free as of 2025, with a public commitment to phase out the remaining products [4].
General Mills committed to removing synthetic dyes from its cereals and K-12 school food products by summer 2026, with the full product portfolio targeted for end of 2027 [4].
Conagra Brands committed to dye-free school foodservice items by the 2026-27 school year, and to reformulating its full retail portfolio by end of 2027 [4].
PepsiCo announced at its April 24, 2025 earnings call that Lay's and Tostitos would be dye-free by end of 2025, with the broader snack portfolio transitioning "in coming years" [4].
A Consumer Reports review published in 2026 found no evidence that any of these six manufacturers had reversed or formally retracted their commitments [9].
The honest summary: most of the reformulations target 2027, not 2026. If you assumed the US food supply was already dye-free based on the April 2025 headlines, it isn't yet. The process is underway and ongoing.
What Does Health Canada's Position Mean for You?
Health Canada has not announced an equivalent phase-out. As of this writing, all six dyes remain on Health Canada's List of Permitted Food Colours, meaning they are legally approved for use in Canadian food products within established usage limits [6].
CBC News reported in 2025 that Canadian health authorities were watching the US situation but had not announced plans to follow [7]. Canadian Grocer covered the question of whether manufacturers operating in Canada would mirror their US reformulations [8].
Here is what that means at the grocery store. When a manufacturer reformulates its US product to remove Red No. 40, it is not legally required to apply the same change to the Canadian version of that product. Some companies will apply the change globally. Others may sell a reformulated US product and a still-dyed Canadian product at the same time. Canada's separate labelling regulations make that possible.
This is not hypothetical. It already happens with other ingredients across different markets.
For Canadian shoppers, the practical conclusion is this: you cannot assume a US reformulation covers what you're buying in a Canadian store. The brands are the same. The products may not be identical.
Can You Track These Dyes on Canadian Labels Right Now?
Yes, and it's simpler than it sounds.
On Canadian food labels, synthetic dyes must be declared in the ingredient list. They appear under their common names: "Red 40," "Yellow 5," "Yellow 6," "Blue 1," "Blue 2," or "Green 3." Some labels use the "FD&C" prefix (e.g., "FD&C Red No. 40"). All are required to appear in the ingredient list in descending order of concentration.
A few categories where they show up most often: flavoured chips, candy, sports drinks, brightly coloured cereals, fruit-flavoured snacks, processed cheese products, and some baked goods and condiments.
Where they almost never appear: plain meats and fish, plain dairy, fresh or frozen produce, plain grains and legumes, and most products with short, recognizable ingredient lists.
The simplest approach is to look at the ingredient list before buying. If you see Red 40, Yellow 5, or any of the six on the label, you know they're in the product. No guesswork required.
Frequently Asked Questions
Are these six synthetic dyes banned in Canada?
No. All six dyes are currently permitted under Health Canada's List of Permitted Food Colours, meaning they are legally approved for use in Canadian food products within established usage limits [6]. Health Canada has not announced a phase-out or restriction equivalent to the US FDA plan [7]. They are legal in Canadian food products as of this writing.
Will brands reformulate their Canadian products too?
Some will, some won't, at least not on the same timeline. The public commitments from Tyson Foods, Nestle USA, and others apply to their US portfolios. Whether those reformulations extend to their Canadian-market products depends on each company's own decision. The best way to know is to check the ingredient list on the specific Canadian product you're buying.
What is the difference between the six-dye phase-out and the Red No. 3 revocation?
Red No. 3 was revoked by the FDA in January 2025 through a mandatory legal action under the Delaney Clause, which prohibits food additives demonstrated to cause cancer in animals [5]. That revocation is binding and takes effect for food and beverages on January 15, 2027. The six-dye phase-out announced in April 2025 is a separate voluntary plan, built on a cooperative understanding with industry rather than a binding regulation [1][2].
Is the six-dye phase-out actually happening, or did it quietly stall?
Based on the public record as of mid-2026, the reformulations are proceeding. No major manufacturer has publicly reversed its commitment, and Consumer Reports' 2026 review confirmed active reformulation across the named companies [9]. The timeline has shifted: most manufacturers are targeting end of 2027, not end of 2026. But the direction has not reversed.
Do natural colorings work as replacements?
Major manufacturers are using a variety of natural colorant alternatives as they reformulate. Annatto (for yellow and orange), beet juice (for red and pink), turmeric (for yellow), and spirulina (for blue and green) are among the alternatives appearing in reformulated US products. Whether any specific replacement performs the same visually and in shelf-life testing varies by product type. This is a manufacturer decision, not a regulatory one.
