Research shows arsenic, mercury and selenium in Asian carp not a health concern to most

29.01.2014
Researchers at the Prairie Research Institute's Illinois Natural History Survey have found that overall, concentrations of arsenic, selenium, and mercury in bighead and silver carp from the lower Illinois River do not appear to be a health concern for a majority of human consumers. The full results of the study have been published in the journal Chemosphere.
Average mercury concentration in fillets was below the US Food and Drug Administration Action Level and EPA Screening Value for Recreational Fishers, though some individual fish had mercury concentrations high enough to recommend limiting consumption by sensitive groups (children

Mercury concentrations were greater in bighead carp and were elevated in both species taken from the confluence of the Illinois and Mississippi rivers. "These fish are low in mercury in comparison to many other commercially available fish. However, as always consumers need to make informed decisions about their food choices," said Dr. Jeff Levengood, lead investigator of the study.

Arsenic and selenium concentrations in bighead and silver carp fillets examined did not pose a risk to human consumers. Inorganic arsenic concentrations were undetectable and concentrations of selenium in carp fillets were well below the 1.5 mg/kg threshold for restricting the number of meals according to the US Environmental Protection Agency. "Carp species, size and collection location should be considered in judging risks associated with uses of these fish taken from the Illinois River ", Levengood said.

Asian Carp in Illinois

Introduced to control algae in retention ponds and wastewater treatment facilities, bighead and silver carp escaped into the Mississippi River during flooding and spread into the Illinois River and Missouri River watersheds. These two Asian carp species impact the ecosystem and fishing industry by outcompeting native fishes for resources. Additionally, their tendency to jump from the water when startled by boat motors has resulted in direct harm to humans, impacting the recreation industry. Commercial harvest of bighead and silver Asian carp species has been proposed as a means to contain the spread of the highly invasive fish. The Illinois River is connected to the Great Lakes via the Chicago Waterway System, leading to concern over potential impacts on the $7 billion Great Lakes fisheries.

Established in 1858, the Illinois Natural History Survey (INHS) mission is to investigate and document the biological resources of Illinois and other areas, and to acquire and provide natural history information that can be used to promote the common understanding, conservation, and management of these resources. With a staff of over 200 scientists and technicians, it is recognized as the premier natural history survey in the nation and is part of the Prairie Research Institute at the University of Illinois. http://www.inhs.illinois.edu.

The Prairie Research Institute at the University of Illinois at Urbana-Champaign is the home of the Illinois State Scientific Surveys: Illinois Natural History Survey, Illinois State Archaeological Survey, Illinois State Geological Survey, Illinois State Water Survey, and Illinois Sustainable Technology Center. The institute is the applied research arm of the state of Illinois, and provides anticipatory research, long-term data collection, and a capacity for rapid deployment and response to sudden or unexpected circumstances. For over 160 years the surveys have applied cutting-edge science and expertise to keep Illinois' economy, environment and people prosperous and secure. http://www.prairie.illinois.edu
