JOPLIN, Mo. —
Kansas health and wildlife officials issued revised fish consumption advisories for 2014 last week.
A number of rivers and lakes in Southeast Kansas are on the list because of elevated pollution levels.
The advisories identify types of fish and aquatic animals that should be eaten in limited quantities or, in some cases, avoided because of contamination of streams, rivers and lakes.
The advisory includes:
• All forms of aquatic life including fish and shellfish because of perchlorate in Horseshoe Lake located in units 22 and 23 of the Mined Lands Wildlife Area in Cherokee County.
• Shellfish — mussels, clams and crayfish — in the Spring River from the confluence of Center Creek to the Kansas/Oklahoma border. The shellfish are contaminated with lead and cadmium.
• Shellfish in Shoal Creek from the Missouri/Kansas border to Empire Lake in Cherokee County, because of lead and cadmium contamination.
State officials also are warning that “sensitive populations” of Kansans should limit their consumption of all types of fish caught in the state to one meal per week because of mercury contamination.
The advisory includes pregnant women, women who may become pregnant, women who are nursing and children age 17 or younger.
The public throughout the state also is advised to restrict consumption of black bass species (largemouth, smallmouth and spotted bass) to one meal per week because of mercury.
The Kansas Department of Health and Environment along with the Kansas Department of Wildlife, Parks and Tourism compiled the list.
Missouri officials have yet not issued their 2014 fish consumption advisory, but the 2013 list warns sensitive populations to limit their consumption of bass and walleye to one meal per month because of mercury contamination.
That advisory is in effect statewide.
Buffalo species greater than 21 inches should not be eaten more than once per week if taken from Turkey Creek in Jasper County because of elevated levels of chlordane and polychlorinated biphenyls, or PCBs.
There are no advisories for the Spring River and Shoal Creek in Missouri, although there is one across the state line.
Gena Terlizzi, spokeswoman for the Missouri Department of Natural Resources, said that while the state issues fish advisories, it does not issue shellfish advisories.
She also said all advisories are based on extensive, annual fish-tissue studies by the Missouri Department of Conservation and the DNR in lakes, ponds, rivers and streams.
“Missouri fish-tissue data do not support an advisory being placed on these water bodies,” she said in a statement e-mailed to The Joplin Globe.
Grand Lake, Tar Creek
The Oklahoma Department of Environmental Quality has not issued its 2014 advisory yet, either, but its 2013 advisory included Spring River, the Tar Creek area and Grand Lake.
The advisory was the result of studies conducted in 2003 and 2007 that showed increased levels of lead in fish collected in Tar Creek area mill ponds, the Spring and Neosho rivers, and Grand Lake.
Based on the studies, residents were advised to limit consumption of carp and freshwater drum in Spring River to no more than three meals per month if the fish were cooked with bones, or nine meals per month with boneless fillets. Lead collects in the bones, according to the department.
Redhorse sucker and smallmouth buffalo consumption should be limited to six meals per month (with bones) if taken from Grand Lake, and eight meals per month (with bones) if taken from the Neosho River.
There are no restrictions on bass species taken in Spring River, but there is on bass — 14 meals per month (with bones) — when taken from area mill ponds.
There were no restrictions on crappie, but sunfish should be limited to two meals per month (with bones) when taken from mill ponds and five meals per month (with bones) when taken from Spring River.
There were no restrictions on sunfish taken from the Neosho River or Grand Lake.
There also were no restrictions on blue or channel catfish taken from the Neosho River or Grand Lake, but there is an advisory of nine meals per month for catfish (with bones) taken from Spring River.
No samples were collected for catfish from mill ponds.
There were no advisories on fish taken from Grand Lake because of mercury, according to the department.
