Red #40
Red #40 appears in 2,295 indexed US food products. No FDA SAFFA status or CSPI rating is attached in this snapshot, so this page reports prevalence rather than a safety verdict.
What the data can answer
Red #40 appears in 2,295 catalogued products, but this snapshot has no FDA SAFFA status or CSPI Chemical Cuisine rating attached to it. This page therefore cannot answer whether the ingredient is safe from those sources. It can show how often it occurs, where it tends to sit on labels, and which kinds of products contain it.

Catalog prevalence comes from Open Food Facts ingredient lists. FDA SAFFA and CSPI Chemical Cuisine labels are shown only when the source record contains them.
How to use this page
Audit the co-occurring flags first
54.2% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Red #40 as the trigger. Open records such as 1% lowfat milk; 100% Juice, Ruby Red Grapefruit; 100% real ice cream and inspect which ingredient row carries the caution marker. The 88.3/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 81% average label depth helps locate the term when checking the package.
54.2% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 2295 of 2295 NOVA-tagged records. That describes the surrounding products, not the substance. For a useful comparison, hold category and processing level constant, then inspect which named component changes alongside the caution flag; otherwise the product mix will confound the ingredient question.
Next check: open the lowest-scoring linked formulation and locate the exact caution-marked component.

- Of the way down the captured list, averaged across the 2,296 products listing it (mean slot 17.2). Red #40 usually falls near the end of the captured list; this position does not measure its amount because source formatting, compound ingredients and labeling exceptions vary.
Ranks use Open Food Facts ingredient rows on this site’s refresh cycle. 247,206 ingredients with ≥1 product appearance enter the ranking. Prevalence and list depth are catalog facts, not toxicology.
What else is usually in the same product as Red #40
Across the 2,295 products on this site that list Red #40, these flagged additives appear alongside it most often. The comparison column is how often each one appears across every product with a parsed ingredient list, so the two figures are measured over the same set. Yellow 5 shows up about 3x more often with Red #40 than in the catalogue at large.
| Additive | Shared products | Share of Red #40 products | Share of all products |
|---|---|---|---|
| Yellow 5 | 335 | 14.6% | 4.8% |

Co-occurrence describes what manufacturers formulate together. It is not a claim that these additives interact, and it carries no regulatory meaning. Counted over products with parsed ingredient lists; Open Food Facts, 2026-09-01.

Frequently Asked Questions
How should I read safety signals when Red #40 sits in heavily flagged products? ▼
54.2% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming Red #40 is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.
