☠️ Red 40 Lake in Pet Food

Grade D-4 ptsPotential Cancer Link

What It Is

"Red 40 dye precipitated onto an insoluble base, used to color fats and oils that a water-soluble dye can't tint evenly."

Health Impact

Chemically and functionally this is still Red 40 — the "lake" form is just a manufacturing trick to make the same dye work in fat-based treats instead of water-based ones. The same hypersensitivity and EU-warning-label concerns apply; the delivery method doesn't change what it is.

Why This Grade

A meaningful red flag: an unnamed source, heavy processing into a by-product or digest form, or documented regulatory scrutiny in at least one country. -4 pts deducted.
