Columbia River Poisened on purpose? ODFW needs to explain !

What Are the Charges Leveled Against ODFW & WDFW? They knew or should have known. We want to know if delayed health warnings were done on purpose?

In the mid-1960s PCBs were detected in soil and wildlife, and concern arose over their possible adverse effects on health and the environment. Research confirmed that some PCB congeners degrade very slowly in the environment and can build up in the food chain, notably in fish and fish-eating birds.

In 1968 a widespread human-poisoning episode in Japan was at first attributed to the consumption of rice-bran oil contaminated with PCBs. In this incident and in a similar incident that occurred in 1978-79 in Taiwan, consumption of PCB-contaminated rice-bran oil resulted in chloracne (a severe form of acne), fatigue, nausea, and liver disorders. There was a preliminary report that liver cancer among Japanese males was significantly increased; however, the uneven geographic distribution of liver cancers between the two areas of western Japan involved in the incident (with a significant increase in liver cancers observed in only one of the areas) suggests that factors other than just the rice-oil poisoning were involved. Nevertheless, the Japan and Taiwan incidents increased the already growing concern over the safety of PCBs.
