What are PCBs?

Polychlorinated biphenyls (PCBs) are a group of manufactured organic chemicals that contain 209 individual chlorinated chemicals (known as congeners). Concentrated PCBs are either oily liquids or solids and are colorless to light yellow in color. They have no known smell or taste. There are no known natural sources of PCBs. Some commercial PCB mixtures are known in the United States by their industrial trade name, Aroclor.

PCBs don't burn easily and are good insulating material. They have been used widely as coolants and lubricants in transformers, capacitors, and other electrical equipment. The manufacture of PCBs stopped in the United States in 1977 because of evidence that they build up in the environment and cause harmful health effects. Products containing PCBs are old fluorescent lighting fixtures, electrical appliances containing PCB capacitors, old microscope oil, and hydraulic fluids.

During the time that PCBs were manufactured, there were often no effective controls on disposal. Because they do not break down easily, PCBs are now found widely distributed in our environment. Generally their concentrations in the environment are quite low. However, the chemical properties of PCBs cause them to be concentrated up the food chain.

Which fish are safe to eat?

In general, eat smaller, younger fish. Small organisms absorb contaminants in the water, and are in turn eaten by small fish. Big fish eat the small fish, and in this way, the contaminants accumulate up the food chain. The top level predators such as walleye and bass contain the highest amounts of contaminants. Since PCBs are stored in fat, smaller, leaner, shorter-lived species such as bluegills, crappie and yellow perch contain very low or undetectable levels of PCBs.

Great Lakes fish and fish from the Mississippi River are more likely to contain PCBs than fish from Wisconsin inland lakes and rivers.

For me it can be complicated and a lot to remember. I go to a fish market and they are well informed.

I am not sure why all this published info is saying these shellfish are safe. Itals/Vegan Macrobiotics do not ever eat shellfish or bottom feeders for the reasons I stated.

Black and Latino custodial workers @ the Capitol Bldg said it was degrading to clean up the debris left by white supremacist who violently stormed the Capitol Bldg. They even had to clean up smeared feces. One staffer said they were used to cleaning up after white supremacist (referring to racist Congressional members). Those who were there that day feared for their life b/c they weren't given any protection.
Mother Jones posted a list of "law makers" nationwide who promoted/assisted in the insurrection on our government. ALL should be ousted, stripped of pensions, charged with sedition and felony murder.
If black folks are present at a crime, whether they participated or not, they're charged with as many violations as white folks can conjure up. Felony murder is top of their list. Why not for white domestic terrorist?
25,000 National Guardsmen are set up to protect for Biden/Harris inauguration! Authorities are AGAIN saying that white domestic terrorist are the largest threat in American and to the democratic process.
NOT Black Lives Matter protestors, NOT even foreign terrorist, but American grown white men who are angry about all the white privilege they have.
Twitter is now locking accounts for unusual activity when there is no unusual activity. Apparently if you post to much to soon, it triggers their spider hairs. Never mind that it's (or was) a platform to post information and opinions, now it's just a flat bed from the ghost-of-trump-past. Jack Dorsey/Twitter should be charged with giving trump the media to incite a resurrection against the United States government.
18 family members tested positive for COVID after a holiday party in Pennsylvania, including a one year old baby. YES of course they were white. The mother knew she had "something", but during a world pandemic she didn't think it was COVID. This is insane! They just keep spreading it!
