Recent Advisory News

  • Down-river tests show more PFCs but state won't alter fish-consumption advisories. MINNESOTA -- Fish collected last fall from the Mississippi River were tested and the results show that perfluorochemical contamination is widespread south of the 3M plant in Cottage Grove. State officials concluded that no new fish consumption advisories are needed and that people should continue to follow the current advice. The agency said that they will continue to monitor the situation with more sampling of different fish species at several locations downstream from the plant.

  • Critics: Fish warnings fail to hook those most at risk. INDIANA -- There is concern that Indiana's annual fish advisory document is not reaching the target audience. The people most affected by the advisories are the anglers, most of whom are not accessing the Internet-only document for information. Health officials are trying to come up with new, practical and more cost-effective ways to distribute the information. In previous years, they distributed hard copies of the document, but it got to be too cumbersome and expensive. Officials want to remind people that no fish should be eaten, by anyone, from the following waterbodies: Clear Creek, Elliot Ditch, Grand Calumet/Indiana Harbor Canal, Little Mississinewa River, Little Sugar Creek/Walnut Fork, Sugar Creek (from Interstate 74 to Indiana Highway 32), Pleasant Run Creek, Wea Creek, Kokomo Creek, Wildcat Creek, Salt Creek and Stoney Creek.

  • Rock River pulled from list of impaired waters, fish advisory changed. Rock County, WI -- Rock River was one of seven waterways removed from the state's list of impaired waters. The Department of Natural Resources has lifted the PCB Advisory, issued in 2000, for Rock River channel catfish caught between the Indianford Dam and the Illinois state line. However, the water body is still subject to the general advisory, recommending that women of childbearing age, those nursing and children under the age of 15 eat one meal of catfish per month. The remaining population is advised to eat one meal per week of catfish.

  • Michigan wants improved fish warnings. MICHIGAN -- A survey conducted from March 2005-March 2006 asked nearly 1100 anglers fishing in the Tittabawassee River, Saginaw Bay, Saginaw River and Shiawassee River about their fish consumption. The study, conducted by the Michigan Department of Community Health, found that several people were eating fish that current advisories recommend against consuming, and that few people were aware of recommendations to limit the number of servings of other fish. Overall, the health department plans on working with the community groups to raise more awareness about the fish consumption advisories.

  • Change in standards delays fish advisories. ALABAMA -- Alabama decided to adopt the more stringent EPA standards for mercury to replace their existing FDA mercury standard. The new measure is four times the measure of protective health, but in doing this, there have been laboratory location and procedural changes that have delayed the release of the annual fish consumption advisories by several months. They are due out by mid to late summer.

  • OEHHA finalizes advisory on mercury in fish in Lake Berryessa and Putah Creek. CALIFORNIA -- The California EPA's Office of Environmental Health Hazard Assessment has modified one fish consumption advisory for Lake Berryessa and issued a new advisory for Putah Creek. Both advisories stem from elevated mercury levels in these two water bodies. The Lake Berryessa guidelines outline the following as recommendations: women of childbearing age and children 17 years old and younger can have one meal per month of largemouth, smallmouth, or spotted bass, catfish or Chinook (king) salmon. One meal a week of bluegill or other sunfish, trout or kokanee is okay for this group. For women beyond childbearing age and men, up to three meals a week of trout or kokanee is okay. One meal a week of the following is an acceptable alternative to the trout or kokanee: largemouth, smallmouth, and spotted bass, catfish, bluegill or other sunfish, and Chinook (king) salmon.

    According to the advisory for Putah Creek, women beyond childbearing age and men can have one meal a week of black bass, crappie or hitch. Alternatively, a daily serving of trout or Sacramento blackfish is fine, or a meal of bluegill, or other sunfish, catfish (including bullheads), sucker, carp or goldfish, or crayfish could be eaten up to three times a week. For women of childbearing age and children 17 and younger, up to three servings a week of trout or Sacramento blackfish is acceptable. One meal a week of any of the following is an acceptable alternative: black bass, bluegill or other sunfish, carp or goldfish, catfish (including bullheads), crappie, sucker, hitch, or crayfish.

  • Fires shine new light on mercury's impact. MINNESOTA -- A U.S. Forest Service fisheries research team is testing fish, water, and soils in an effort to determine the impact of forest fires on mercury levels in fish. The theory is that mercury is deposited in the forest from rain and snow. The mercury builds up over time and is then rapidly released in the event of a forest fire. The joint team of scientists from the Forest Service, the University of Minnesota, and the U.S. Geological Survey is examining possible relationships between the forest fires and elevated mercury levels in the lakes, surrounding soil, and the fish. They are collecting perch from several lakes and so far have noticed that when mercury levels in the fish are higher, they are also higher in the surrounding soil and secondly, that lake size is also important. Of the lakes they have sampled, larger lakes show lower levels of mercury while the smaller lakes show higher mercury levels.

  • New warning for canned tuna. NATIONWIDE -- Consumer Reports magazine, published by the Consumers Union, is recommending that pregnant women avoid consuming canned light tuna, as well as Chilean sea bass, halibut, American lobster and Spanish mackerel because of mercury concerns. The Consumer Reports decision is based on the latest testing by the Food and Drug Administration and an investigation by the Chicago Tribune. The newspaper's reports found high levels of mercury in 15 percent of the canned light tuna they tested. The FDA found 6 percent of their 2000-2005 canned light tuna samples to be above the average levels for albacore, a fish the federal government advises pregnant women and children to limit consuming. The Consumers Union felt it was important to bring these results to the public's attention by publishing these findings in the July 2006 issue of the magazine. The FDA and the tuna industry have stood behind their conclusions that despite some high level mercury results, the overall average mercury level in canned light tuna is low and therefore no public warning is needed.

  • University of Wisconsin-Milwaukee Researcher's 12-year study of Great Lakes fish consumption by Native tribes holds surprises. A professor at UWM's College of Health Sciences has completed a 12-year study among 822 volunteer adult members of the Ojibwe Tribe of the northern Great Lakes region. His work examined the effects of large quantities of fish consumption. Overall, the mercury levels in the people he studied were twice the levels in people who do not eat as much fish. However, he views that mainly as an indicator that the members of the Ojibwe tribe were eating fish, not as a red flag for mercury-related health problems. On average, the mercury levels were lower than the U.S. Government limit of 1 ppm mercury in fish.

  • Body burdens of mercury in lower Hudson River area anglers. Blood samples and questionnaires from 191 anglers were evaluated. Results indicated that participants who reported eating fish caught from the lower Hudson River (a federally designated Superfund site with health advisories) had significantly higher mercury concentrations in their blood samples. This study also showed that there was a positive dose-response relationship in which the blood metal concentration increases as consumption frequency increases. This study supports the theory that consumption of fish from the lower Hudson River is a human exposure pathway to mercury.

  • A screening-level assessment of lead, cadmium, and zinc in fish and crayfish from Northeastern Oklahoma. This study evaluated the human and ecological risks of metals in fish (common carp, channel catfish, flathead catfish, largemouth bass, spotted bass, and white crappie) and crayfish collected from the Spring and Neosho Rivers. Comparison of sample results and current criteria for lead, cadmium, and zinc indicated that human consumption of carp and crayfish could be restricted from elevated levels of these metals. Similarly, channel catfish consumption could be restricted due to elevated lead concentrations.

  • Bioaccumulation of heavy metals in water, sediment, aquatic plants and tissues of Cyprinus carpio from Kizilirmak, Turkey. The objective of this study was to evaluate the applicability of Cyprinus carpio's tissue as a biomonitor of metal accumulation. Metal (Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn) concentrations were measured in fish tissues. In addition, the relationships of metal concentrations in organs to concentrations in water, aquatic plants, and sediments were compared. Results indicated that with the exception of Mn, metal concentrations were highest in the kidney. Concentrations of Pb, Mn, and Zn were found to be above the FAO/WHO limits, EU, and Turkish Food Codes proposed for fish, suggesting that the edible parts of these carp in the study region may not be safe for human consumption.

  • Heavy metal concentrations in Malapterurus electricus and Chrysichthys nigrodigitatus from Ogba River in Benin City Nigeria. The purpose of this study is to evaluate the level of pollution in the Ogba River in Benin City, Nigeria. Heavy metal concentrations in Malapterurus electricus and Chrysichthys nigrodigitatus collected from the river was analyzed and results indicated that Cu, Mn, Cr, and Ni concentrations in both fish exceeded the WHO and FEPA recommended maximum allowable standards in food fish. This study concluded that consumption of fish from the Ogba River may be a potential health hazard to humans.
