Ou
Ou appears in 5 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
Ou appears in 5 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: 1 of 5 records have some flagged component, while the rest do not. Compare Cheerios au miel et aux noix; Mashed Potatoes Butter & Herb; Mocha Latte Bar to see how surrounding formulations change; do not assign their 60–100 score range to Ou itself. The ingredient most often sits in the upper half of the list, and Plant-based foods and beverages supplies the most useful like-for-like starting point for a label review.
1 of 5 linked records have some flagged component
All 4 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 60–100 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.

How do the sampled products compare?
Each point is one of the 5 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.
