Leek
Leek appears in 211 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
Leek appears in 211 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
Use prevalence before concern
Only 18.5% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Leek spans 89 named brands and is led by the Meals group. Start with Albacore Tuna in Water, No Added Salt; Artichoke Spinach Dip Mix; Artificial Pork Flavor when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 98.3/100 product average proves this ingredient safe.
89 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 167 of 208 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.
What else is usually in the same product as Leek
Across the 211 products on this site that list Leek, 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 2.4x more often with Leek than in the catalogue at large.
| Additive | Shared products | Share of Leek products | Share of all products |
|---|---|---|---|
| Caramel Coloring | 29 | 13.7% | 5.7% |
| Carrageenan | 6 | 2.8% | 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.
