Standards and Sourcing (From Appendix 2)

Fish not allowed. Water pollution and microplastics also prohibit its inclusion.

Rationale (From Appendix 3)

Fishy business

Fish contamination occurs in growth, harvest, processing, and sales. But because edible fish grow in polluted oceans and freshwater lakes, rivers and streams, they can accumulate contaminates from many sources in their natural environment.

Because chemical contamination grows with time, this set of recommendations from the state of Washington recommends eating smaller, younger fish. It also recommends cutting away the fatty portions of fish such as salmon because some chemicals are lipophilic. Other contaminates such as methyl mercury, are water soluble.

Beware of farmed fish

Studies have determined that farmed fish are subject to contamination by multiple chemicals (Friends Don???t Let Friends Eat Farmed Salmon). Feed is one suspect as are chemicals and pharmaceuticals added to keep fish as healthy as possible in crowded pens.
