What the data can answer
Blue #1 & 2 appears in 2 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.

Reading this ingredient record
Audit the co-occurring flags first
100% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Blue #1 & 2 as the trigger. Open records such as Giant gummy, cola bottle!; Christmas cookie assortment and inspect which ingredient row carries the caution marker. The 65.0/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 54% average label depth helps locate the term when checking the package.
100% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 2 of 2 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.
