Recent Advisory News

  • Warning: don't eat the fish from these local waters. TENNESSEE - Tennessee Department of Environment and Conservation recently lowered the contaminant level that would trigger a mercury fish consumption advisory. This resulted in addition of new fish advisories in various state lakes and rivers. The state agency will put up signs at major access points to warn anglers of the new advisories.

  • DNR reminds anglers to follow fish consumption advisories. MINNESOTA - State Department of Health recently issued new fish consumption advisories in Lake of the Isles, Calhoun, Harriet, Brownie and Cedar lakes, and in the Mississippi River downstream of Minneapolis.

  • Environmental quality officials warn about mercury in Utah trout. UTAH - State Department of Environmental Quality recently issued a number of consumption advisories for trout collected from waterbodies in northern and southern Utah due to elevated mercury levels.

  • State warns of mercury in some fish caught near Trinidad. COLORADO - State health officials recently issued new consumption advisories for fish collected from Trinidad Lake and Horseshoe Reservoir due to elevated mercury levels.

  • Lagoon fish unsafe to eat, officials say. SOUTH CAROLINA - Due to the lack of resources, the state health department is not routinely monitoring contaminant levels in fish collected from storm water ponds and lagoons. State environmental officials remind anglers of the potential health risks associated with consumption of fish caught in these smaller water bodies. Relatively higher levels of pollutants such as fertilizers, herbicides, pesticides, and petroleum products are commonly associated with these water bodies and therefore fish from these ponds and lagoons are probably not safe to eat.

Current Events, News and Journal Articles

  • Fish does not protect the heart, researchers say. WASHINGTON - This article summarizes the findings from a recent study issued in the May issue of the American Journal of Cardiology. In brief, the study concluded that the observed benefits to the heart that are associated with fish consumption are due to overall healthier dietary patterns, as opposed to specific omega-3 fatty acids from fish.

  • Toxin found in popular fish snacks. HONG KONG - This article summarizes results of a study conducted in Hong Kong which evaluated contaminant levels in dried meat snacks. In brief, the study found elevated arsenic levels in 36% of the dried shredded squid sample tested.

  • Persistent halogenated hydrocarbons in consumer fish of China: regional and global implications for human exposure. This article summarizes the findings of a study which evaluated the concentrations of persistent halogenated hydrocarbons (PHHs) in 13 fish species from a major fish-farming region of China. The authors concluded that in general, no significant health risks would be associated with the consumption of freshwater farmed and wild marine fish. However, the authors advised consumers to limit consumption of seawater farmed fish.

  • Seafood arsenic: implications for human risk assessment. The authors studied the forms and levels of arsenic in dietary seafood and evaluated the metabolic process and fate of these arsenic compounds. The authors estimated the margin of exposure between carcinogenic doses used in rodent studies and those expected after human consumption of large quantities of seafood to be a minimum of 103 to 104.

  • Evaluating regional predictive capacity of a process-based mercury exposure model, regional-mercury cycling model, applied to 91 Vermont and New Hampshire lakes and ponds, USA. The authors conducted a feasibility study to evaluate if the regional mercury cycling model is a good application for developing regional fish advisories using existing data. Results indicated that the model is not a good a priori predictive tool and therefore cannot be used for the regional scale analyses.
