    Kansas Issues Revised Fish Consumption Advisories
    Saturday, December 06, 2008 :: infoZine Staff
    The Kansas Department of Health and Environment (KDHE) and the Kansas Department of Wildlife and Parks (KDWP) are issuing revised fish consumption advisories for 2009. The advisories identify species of fish that should be eaten in limited quantities or, in some cases, avoided altogether because of contamination found in tested fish.


    topeka, KS - infoZine - The advisories include guidelines for mercury and polychlorinated biphenyls (PCBs) in fish, perchlorate in fish and other aquatic life, and lead and cadmium in shellfish. Data from most Kansas long-term monitoring sites show a decrease in PCB levels and no trend in mercury concentrations. PCBs have not been in use in the U.S. since the 1970s, and chlordane use was discontinued in 1988.

    Chlordane levels have declined dramatically statewide, and PCB levels are expected to follow. PCBs and chlordane degrade slowly, so it takes decades for them to be completely removed from the environment, even after use is discontinued.

    Kansas recommends not eating specified fish or aquatic life from the following locations:


    The Kansas River from Lawrence (below Bowersock Dam) downstream to Eudora at the confluence of the Wakarusa River (Douglas and Leavenworth counties) for bottom-feeding fish (carp, blue catfish, channel catfish, flathead catfish, freshwater drum, bullheads, sturgeons, buffalos, carpsuckers and other sucker species) because of PCB levels;


    Horseshoe Lake located in units 22 and 23 of the Mined Lands Wildlife Area (Cherokee County) for all forms of aquatic life in addition to all fish because of perchlorate levels;


    The Spring River from the confluence of Center Creek to the Kansas/Oklahoma border (Cherokee County) for shellfish (mussels, clams, and crayfish) because of lead and cadmium levels;


    Shoal Creek from the Missouri/Kansas border to Empire Lake (Cherokee County for shellfish because of lead and cadmium levels.


    In addition, Kansas recommends a limit of one 8-ounce serving per month, or twelve 8-ounce servings per year, on the consumption of bottom-feeding fish from the following locations due to PCBs:


    The Arkansas River from the Lincoln Street dam in Wichita downstream to the confluence with Cowskin Creek near Belle Plaine (Sedgwick and Sumner counties);

    Cow Creek in Hutchinson and downstream to the confluence with the Arkansas River (Reno County).


    Due to mercury contamination, Kansas recommends a limit of one 8-ounce serving per week for adults or one 4-ounce serving per week for children (twelve years or younger) of any species of fish from the following locations:


    The Little Arkansas River from the Main Street Bridge immediately west of Valley Center to the confluence with the Arkansas River in Wichita (Sedgwick County);

    The main stem of the Blue River from U.S. 69 Highway to the Kansas/Missouri state line (Johnson County).


    Kansas counties with current fish consumption advisories include: Cherokee, Douglas, Johnson, Leavenworth, Reno, Sedgwick and Sumner counties.

    In 2004, the Environmental Protection Agency (EPA) issued a nationwide consumption advisory for locally caught fish, based on nationwide average mercury levels in a variety of fish. Many states east of Kansas have mercury fish consumption advisories that include a mix of water body specific and statewide advisories. EPA recommends that consumers limit consumption of any locally caught fish to not more than one 8-ounce meal per week. The advisory is designed to protect consumers in states lacking fish contaminant data. EPA further indicates that where there is better information, state advisories should take precedence. The EPA advisory rationale is found at: ( PDF ).

    Since 2004, KDHE has been collecting fish tissue samples from both lakes and streams. These samples are taken from bottom-feeding fish and from predatory fish (basses, crappie, walleye) in lakes. Mercury tends to accumulate in predatory fish to a greater extent than in bottom-feeding fish. Prior fish tissue contaminant monitoring efforts had largely focused on bottom-feeding fish and legacy organochlorine pesticides and other organic chemical contaminants (DDT, dieldrin, chlordane, PCBs, etc.). Average mercury concentrations in Kansas fishes are clearly lower than nationwide averages. KDHE protocol requires use of the average tissue mercury level when conducting water body specific risk assessments. However, when considering the condition of the State’s water bodies as a whole, the median concentration is a better indicator of central tendency and is somewhat lower than the average.

    Consumers of Kansas fish can safely eat at least two 8-ounce fish meals per week from any Kansas water body not under a specific KDHE/KDWP advisory. Data suggest higher levels of consumption are safe for most consumers. In about 5 years data should be adequate for conducting individual risk assessments for our largest and/or most heavily fished and harvested lakes.

    Women who are pregnant or nursing may wish to consult with their physician about safe levels of fish consumption and mercury exposure. This sensitive group, and children under twelve, should restrict their total mercury intake as related to both supermarket fish and locally caught species. Information on the FDA/EPA commercial fish advisory is available at: www.epa.gov/fishadvisories/advice/ .

    Fish consumption advisories assess cancer risk levels using EPA methods. Cancer risk assessment is a method to determine the added increase in cancer levels in a population if fish in the advisory areas are consumed regularly over a 70-year period. Assessments that estimate the increased risk of cancer as greater than one in 100,000 are determined to be unacceptably high. Risk assessments for contaminants assessed as non-carcinogens (mercury, lead, cadmium) were based on 8-ounce serving size for adults and 4-ounce serving size for children nine to eighteen years of age.

    Additional testing for contaminants in fish and other aquatic life will continue. Information on the Kansas Fish Tissue Contaminant Monitoring Program can be found at: www.kdheks.gov/befs/fish_tissue_monitoring.htm .

    Sad.:sad2: Not new news but still sad.
    All more the reason to CPR. Especially the big ones.
    I wish I didnt have to drive 50 miles to keep a fish.:smile2:
    They shouldnt allow the harvest of fish from the above mentioned stretches of river. They taste bad, and shouldnt even be persued.
    The banks are contaminated and should be avoided also.:wink::smile2:

    Have a nice day.:smile2:

    They need to put up a sign at Eudora to tell the contaminated fish that they can't swim any further downstream.

    Thanks for the post eric. I have fished some places I dont eat the fish from because of the trash dumps and upstream runoffs:confused2:. I believe the five year study will show some astounding results in the lakes.

    do not eat the fish from these areas they say. makes you wonder how much of these toxins they remove form our drinking water before it gets to your home:confused2:

    Gary, if they did that sign you was talking about it would be like changing
    the subject. It wouldn't be a fish consumption advisory anymore. It would
    be simply a fish advisory. Also, I've never met a fish that could read a sign.
    Technically, I don't think it's within the official capacities of the KDWP to
    require a fish to do anything. Far as I know, most fish just sort of ignore
    humans in general and fish & game officers in particular. Must be why fish
    & game people like to shock them fish so much. Must be frustrating to be
    in charge of critters with so little respect for Kansas law.

    I'm sure we could all use a few more contaminants in our diet, if it comes
    to that, Tom. I would like to be a glowing example of modern health and
    a few extra limbs wouldn't be that bad either.
