Contaminant
Hexavalent chromium
A toxic industrial form of chromium.
What it is
Hexavalent chromium enters waterways from metal plating, tanning, and industrial discharge, and can accumulate in fish. It is a known carcinogen and irritant, and long-term exposure is linked to cancer and liver and kidney damage. Follow the meal limits shown.
Cleaning and cooking will not help
Trimming, skinning, and cooking won't lower it — it's stored in the muscle. Reduce exposure by eating smaller, younger fish and fewer meals.
How to prepare it
- Trimming and skinning won't help — this settles in the muscle you eat, not the fat.
- Cooking doesn't remove it either; a fillet carries the same amount cooked or raw.
- Eat smaller, younger fish — they carry less.
- Follow the meal limits above and space your meals out across the month.
