The West Virginia Sport fish Consumption Advisory
Why is a fish consumption advisory needed?
While most West Virginia sport fish are of high quality, low levels of
chemicals like polychlorinated biphenyls (PCBs), mercury and dioxin have been
found in some fish from certain waters. To ensure the continued good health of
West Virginians, the West Virginia Department of Health and Human Resources
offers an advisory for how often these fish can be safely eaten. An advisory is
advice, and should not be viewed as law or regulation. It is intended to help
fishermen and their families make educated choices about: where you fish, what
types of fish you eat, how to limit the amount and frequency of fish you
consume, and how you prepare fish for cooking.
By following these advisories, you can get the health benefits of
eating fish and
reduce unwanted contaminants.
Where can I get advisory information?
Advisory information is included in the DNR 2005 fishing regulations
which can be
obtained at DNR offices or any location that issues fishing licenses. Note that new advisories may be issued after the
regulations are printed as more data become available.
Contact the following state agencies or visit their websites:
A detailed technical document, the "West
Virginia Sport Fish Consumption Advisory Guide"
is available in Adobe PDF format (285k). This document is the
method for calculating the meal consumption limits upon which the advisories are
issued.
If you do not have Adobe Acrobat Reader installed on your computer, you
can download it free from Adobe's website at:
http://www.adobe.com/products/acrobat.
The national repository for state consumption advisories may be found at
http://www.epa.gov/ost/fish/
What about fish from the grocery or
restaurants?
This advisory covers only sport fish caught in West
Virginia. Safety regulations and advisories for fish in the market place
are the responsibility of the Federal Food and Drug Administration (FDA). Most
kinds of fish on the market are safe and the FDA encourages consumption of up to
12 ounces of fish per week.
The FDA and USEPA recently issued a joint advisory for women of
childbearing age and children. They recommend that women of childbearing age and
children limit their intake of fish, including store bought fish and tuna, to 2
to 3 meals per week (12 oz. of fish per week for an adult woman). For more
information about that advisory, see
http://www.fda.gov/bbs/topics/news/2004/NEW01038.html.
Based upon national advisory information issued by FDA, the following species
of fish could pose health problems for some individuals. Avoid these kinds of
fish if you are concerned about your exposure to chemical contaminants:
Shark
Swordfish
King mackerel
Tilefish (also called golden snapper or golden bass)
What contaminants are looked for to
determine if a fish advisory is needed?
Historically, West Virginia fish samples
have been analyzed for a variety of
contaminants. The most recent statewide survey looked for mercury and PCB’s in
fish tissue. Except in a few special cases given on the advisory list,
mercury and PCBs are responsible for the advisories issued for West Virginia
Sport Fish.
If I eat a fish that is listed at a
recommended consumption frequency of one meal per month for mercury, can I also
eat a fish that is listed at a recommended consumption frequency of one meal per
month for PCBs?
Yes. PCBs and mercury affect different body processes, it is considered safe
to eat a fish that has an advisory due to mercury and another fish that has an
advisory due to PCBs, even if they have the same meal frequency suggested.
However, most of the advisories involve multiple contaminants and you may be
eating more of a contaminant than would be safe. You should carefully weigh this
option.
Why does West Virginia
have a more restrictive guidance on some sport fish?
Fish taken from rivers, streams, lakes and reservoirs throughout West
Virginia often have small amounts of chemical contaminants.
Biological and chemical processes that affect a fish's uptake of a particular
contaminant can vary from stream to stream or from fish species to fish
species. Data from a variety of waters and fish species are reviewed and
incorporated into the advisories. Data collected from lakes and rivers in
West Virginia show that a statewide advisory is appropriate. For more
information about locations and fish that have been sampled, see
www.wvdhhr.org/fish.
The lake where I fish seems dirty, but the
fish have been sampled and there is no advisory. How can the lake seem dirty but
the fish not have an advisory?
West Virginia evaluates fish tissue contaminants to decide whether or not to
issue a fish consumption advisory. You cannot see, smell, or taste these fish
contaminants at levels that can affect your health. Therefore, a lake can look
dirty, yet the fish in it can be uncontaminated. Conversely, a lake can look
clean and the fish can be contaminated and require an advisory. Some things that
cause a lake to seem dirty, such as sediment that makes the water look muddy, or
bacteria and algae (microscopic plants) that can produce an odor, do not
contaminate fish tissue. Therefore, you cannot tell if there should be a fish
advisory by whether the lake looks or smells "dirty".
What is the meal portion or serving size
used in this advisory?
The size of the fish meal depends on your body weight. To adjust serving
sizes, follow the advice in the meal size table.
Please note that consumption advice is given in terms of meals for a given
period such as a meal a week. Unless otherwise specified, an eight-ounce meal
size is the standard amount allowed for an "average" adult. The average adult
weighs approximately 150 pounds (equivalent to 70 kg). Because you and your
family members may weigh more or less than the average adult, you can use the
following table as a general guide to adjust serving sizes to body weight.

I weigh more than 151
pounds, why can't I eat more than 8 ounces of fish?
Technically if you weigh significantly more than 151
pounds, you could safely eat a fish meal larger than 8 ounces. However, a
healthy diet includes restricting calorie intake to reasonable levels.
Therefore, meals consisting of more than 8 ounces of protein are not encouraged.
Will there be changes in this advisory?
Changes in the current advisory may occur as new
information becomes available. Should any information change, the advisory will
be updated accordingly. The most up to date information will be on the WVDHHR
website.
This website is a collaborative effort of West Virginia's
Bureau for Public Health,
Division of Natural Resources, and
Department of Environmental Protection
and is maintained by the
Office of Environmental Health Services. For questions regarding the
site's content, please contact these
offices. For questions or problems
related to the website in general, please e-mail the
webmaster.
Do other states have this problem and have
advisories?
Yes. Advisories of some type are in place in Ohio, Kentucky, Maryland,
Pennsylvania and Virginia. Many of these advisories are due to PCB’s, mercury
and dioxin.
How do I know what the fish look like?
The fishing regulations issued by the Division of Natural Resources have a
chart of common West Virginia game fish or check the DNR website
at
http://www.wvdnr.gov/fishing/sport_fish.asp. Regulations are also
available from the Division of Natural Resources' district offices and from
license agents across the state.
Has the lake or river where I like to
fish been sampled for contaminated fish?
To see if the place
you fish has been sampled look at the DHHR website at
www.wvdhhr.org/fish. Since not all waterbodies have been
sampled, it is recommended that the general advisory information be followed.
