Applegate Lake, Ore. -- For the first time in Applegate Lake's history, the Oregon Health Authority issues an advisory about high mercury levels in some of the fish.
"The mercury is probably not new but this is the first time we've had data showing that's a problem," said Oregon Health Authority Toxicologist Dave Farrer.
The Oregon Health Authority issued the warning Thursday, asking those who consume fish from Applegate Lake to lessen their consumption.
"Bass, bluegill, and black crappie, based on those mercury, concentrations, that were measured, we are recommending some meal restrictions on those species of fish," Farrer said.
The O.H.A. recommends not eating more than 5 large bass meals and 13 pan-fish meals per month.
But pregnant woman and children need to eat substantially less. The health authority suggests they eat no more than 2 bass meals and 4 meals of pan-fish a month.
kristin Salamone, a nurse at Providence Hospital in Medford says pregnant and breast feeding mothers, along with children should avoid the fish all together.
"It does have adverse effects on cognitive developments in babies, and their motor skills," said Salamone.
But if you chance it or even stay in the recommended amounts, there are possible side effects to know about.
"They'll get pins and needles sensation, they'll also muscle weakness, trouble hearing, trouble walking possibly," she said.
Salamone says if you feel any of those symptoms, call your doctor immediately.
Despite the O.H.A.'s announcement, employees at the general store at Applegate Lake say they aren't too concerned about the restrictions.
They point out that the majority of the fish in the lake are trout, which have been deemed safe to eat.
