TOPEKA, Kan. (AP) — The Kansas state health department has not received a single report on the handling of fetal tissue in the 15 years that it’s been legally required whenever such tissue is transferred.

The Department of Health and Environment’s disclosure — in response to an Associated Press open records request — comes amid a national debate about fetal tissue. It was spurred by anti-abortion activists’ release of videos showing Planned Parenthood officials outside Kansas discussing their handling of fetal tissue.

A 2000 Kansas law banning the sale of fetal tissue requires anyone legally donating it to someone else to file a report providing details.

The state’s abortion providers say they don’t have such donation programs. Abortion opponents said Thursday another possible explanation is that the requirement is being ignored.
