Well if ya eat ‘em they are dead anyway. Just a matter of timing. I don’t like salmon or tuna for that matter. Much prefer pike, whitefish, or good ole crappies. I won’t vote one dollar for research on using wood spoke or steel wheels. ---

> [@texases](#): > > And in related news, it looks like getting lead out of gas was a GREAT idea: Doesn’t surprise me. But the dangers of lead have been established for decades. Long before it was ever removed from gas or pipes. Once it gets into the air-we-breath and the food-chain it can be extremely harmful. ---

The link provides a technical paper that shows how the chemicals may reach the salmon but I didn’t see where in the body it was detected. If it’s in the meat, does that imply that Coho salmon are dangerous for human consumption in the same way that tuna, or any large predatory fish, is (e.g. mercury)? ---

In pristine Minnesota, the health dept puts out an annual fish advisory on how many of which fish can be eaten before exceeding safe limits. Still one has to wonder what the excuse now is for mental health melt downs? Guess there will always be something driving people wild. In basic training my girl friend now wife sent me a greeting card asking me what my excuse was. It was a picture of a man with crippled hands. Guess implying I wasn’t writing enough. Before computers where you could zip off a text or email with no effort. Maybe it’s the computers and not lead? ---

Town I grew up in is a huge draw for people doing Salmon fishing. Mercury content is a big concern there - all from industrial discharge. There’s a lake in Syracuse NY (Onondaga) that is loaded with Mercury. Allied Chemical dumped TONS of Mercury into the lake spanning decades. It’s a very big lake. ---

Yeah it’s better to eat vegetables from Mexico fertilized with human waste. We buy corn fed animals from local sources. The cows are happy until they are not. ---

All types of toxins bioaccumulate in the flesh of animals and fish. Better to eat the plants and vegetables “straight-up,” thus lower down on the food chain. Better for the environment, save on the water supply, the transportation, the refrigeration, the slaughterhouse waste. And all our health. All countries use human waste in more form or another in agriculture, my neighbors do here in Maine, "Humanure… Ever hear of PFAS in municipal sewage sludge, sold to dairy farmers as the “next great thing?” You get three chances a day to make smart food choices. Your move… ---

> [@bing](#): > > Yeah it’s better to eat vegetables from Mexico fertilized with human waste Why go that far? Your neighbors in the US use human waste as a fertilizer. When treated properly, it is safe. Basically it has to heated, made alkaline, and sit around for 6 to 12 months before the dangerous microbes are killed. Here’s an article that discusses it. Its use is pretty widespread. ---

> [@jtsanders](#): > > Your neighbors in the US use human waste as a fertilizer. When treated properly, it is safe. Tell that to the farmers in Maine that spread biosolids from waste water and now their land is polluted with PFAS. Can’t eat vegetables grown there or animals that grazed the land. It is no longer viable as farmland…I saw recently, there are now other states with the same problem. ---

The PFAS came from people’s excrement so they are already contaminated aren’t they? I’m not saying it’s right only that the barn door is already open. ---

Not exactly. If people had excreted that amount of PFAS, they would all be dead. The PFAS came from industrial waste water mixed with municipal sewage. When treated, the remaining biosolids are left over and a disposal issue. Using those biosolids as fertilizer was looked at as a win-win but that was before they realized there were man-made chemicals (PFAS in particular) that were left in the biosolids that did not break down or be removed by treatment plants. Nothing breaks them down, that’s why they are called “forever chemicals” and they are poisonous to living creatures that consume them. There is no way to treat them properly to make them safe, they need to be contained in some type of vault that will not leach out until we come up with a way to eliminate the hazard. What has happened already is almost irreversible. But that does not mean we shouldn’t raise the alarm and stop spreading biosolids on our farmlands. That is, as they say, cr@pping where you eat… [Next page](https://community.cartalk.com/t/common-tire-chemical-implicated-in-mysterious-deaths-of-at-risk-salmon/198244.md?page=2)
