Elevated Mercury Level Found in Center Pond Fish

BECKET, Mass. — The state Department of Public Health has issued an advisory after a mercury-contaminated fish was found in Center Pond. 
 
According to a letter sent to the local Board of Health from the Division of Environmental Toxicology, Hazard Assessment and Prevention, elevated levels of mercury were measured in the sample taken from the pond. 
 
The concentration in the fish exceeded DPH's action level of 0.5 milligrams per kilogram, or parts per million. 
 
"This indicates that daily consumption of fish from the waterbody may pose a health concern. Therefore, DPH has issued a FCA for Center Pond recommending that sensitive populations should not eat chain pickerel and all other people should limit consumption of chain pickerel to 2 meals/month," the letter states.
 
The letter specifically points to chain pickerel, but the 60-acre pond also has largemouth and smallmouth bass and yellow perch.
 
The "sensitive populations" include children younger than 12, those who are nursing, pregnant, or who may become pregnant.
 
The Toxicology Division recommends reducing intake of "large, predatory fish" or fish that feed on the bottoms of waterbodies, such as largemouth bass and carp. More information on safely eating fish can be found here
