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.
