Oyster
Oyster appears in 124 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
Oyster appears in 124 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.
What this page can and cannot answer
Audit the co-occurring flags first
59.7% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Oyster as the trigger. Open records such as Asian-Style Chicken For Lettuce Wraps; B.B.Q. PORK BAO; Bao and inspect which ingredient row carries the caution marker. The 95.6/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 57% average label depth helps locate the term when checking the package.
59.7% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 105 of 120 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.

What else is usually in the same product as Oyster
Across the 124 products on this site that list Oyster, 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. Caramel Coloring shows up about 10.2x more often with Oyster than in the catalogue at large.
| Additive | Shared products | Share of Oyster products | Share of all products |
|---|---|---|---|
| Caramel Coloring | 72 | 58.1% | 5.7% |
| Carrageenan | 6 | 4.8% | 4.5% |
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.
How do the sampled products compare?
Each point is one of the 16 sampled products listed below: its overall safety score against how many separately flagged ingredients its label carries. Bubble size is the number of ingredient rows the label actually resolved to.

How should I read safety signals when Oyster sits in heavily flagged products? ▼
