Shiitake

Shiitake appears in 88 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

Shiitake appears in 88 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.

Derived by this site from the ingredient lists of every catalogued product (Open Food Facts), recomputed on each data refresh. 247,206 ingredients have at least one appearance and are ranked here. Usage and list position describe prevalence, not safety.

Reading this ingredient record

Use prevalence before concern

Only 2.3% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Shiitake spans 54 named brands and is led by the Plant-based foods and beverages group. Start with All in one nutrition shake; All Natural Hot & Sour Soup; AnSungTangMyun Noodle when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 99.8/100 product average proves this ingredient safe.

54 named brands carry this ingredient

The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 57 of 73 classified products, leaving a meaningful remainder elsewhere. This breadth is why the page reports label depth, category, and product examples separately. Those dimensions help locate comparable products; combining them into a stronger safety claim would hide the variation the catalog actually contains.

Next check: compare label position across two brands before treating prevalence as equivalent exposure.

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.
