It might help if people who actually eat the fish were warned:
The N.C. Division of Public Health, which issued the advisory for PCB-laden channel catfish, says it relies on news reports and its website to alert the public. Because signs are expensive, the division says, they go up only when communities request them and help with the cost.
You might want to ask yourself: Why would county commissioners (or other community leaders) want to request help/spend money for signs that could scare away tourists? This is a state-level responsibility, not a pass-the-hat, elective enhancement.
Stanley and Montgomery counties spent $2,100 to install metal signs around Badin Lake, where the state issued a similar advisory in 2009, said state public health spokeswoman Julie Henry. A follow-up study found them effective, depending on where they were placed.
Language barriers are among factors that can limit their helpfulness.
That last part elicited this lovely comment from a reader:
Could be a way to be rid of illegals that can't read or speak english.
If that was supposed to be a joke, it ain't funny.
