State health and wildlife officials still recommend not eating bottom-feeding fish from the Kansas River between the Bowersock Dam in Lawrence downstream to Eudora.

The Kansas Department of Health and Environment and Kansas Department of Wildlife and Parks on Monday issued their fish consumption advisories for 2010.

Due to levels of polychlorinated biphenyls, officials recommend people not eat carp, blue catfish, channel catfish, flathead catfish, freshwater drum, bullheads, sturgeons, buffalos, carpsuckers and other sucker species from the Kaw from the dam to the confluence of the Wakarusa River northeast of Eudora.

This matches the 2009 recommendations.

According to the agencies, data from most long-term monitoring sites show a decrease in PCB levels. PCBs have not been produced in the United States since the 1970s, but the compounds degrade slowly and take decades to be completely removed from the environment, according to the KDHE.
