Shellfish
Shellfish appears in 154 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
Shellfish appears in 154 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.

What this page can and cannot answer
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 39 of 154 records have some flagged component, while the rest do not. Compare 100% Whey Protein Vanilla Flavor Protein Powder; Apple Fritters; Autumn Grain Salad w/ Champagne Vinaigrette to see how surrounding formulations change; do not assign their 0–100 score range to Shellfish itself. The ingredient most often sits near the end of the captured list, and Dietary supplements supplies the most useful like-for-like starting point for a label review.
39 of 154 linked records have some flagged component
All 136 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 0–100 score spread more informative than the average alone: investigate the low end, identify the actual flagged row, and compare it with a similar unflagged formulation before drawing a conclusion.
Next check: pair one flagged product with a similar unflagged product from the same shelf category.
