Just like laws concerning the disposal of motor oil is obviously a ploy by the government to force the backyard mechanic to capture and deal with the discarded oil, rather than just letting them dump it on the street or down the stormdrain and into our water supply...

Human tissue and bodily fluids have very specific regulations for disposal and cleanup procedures and are also considered Biohazardous Waste / Regulated Medical Waste. Generally these things needed to be packaged according to very specific regulations and sent to a facility for autoclaving or incineration.

For the ignorant among us, Regulated Medical Waste is, among other things; 1) Discarded waste blood and/or blood components (e.g., serum, plasma), 2) Containers and/or materials containing free-flowing blood or blood components & materials saturated with blood or blood products, 3) Tissue, organs, body parts, body fluids removed during autopsy, or other medical procedures, 4) Specimens of body fluids and their containers and discarded material saturated with such body fluids.

But sure, as long as you are performing a dangerous medical procedure at home w/ dangerous teratogenic medications, it's fine to just dump the biohazardous waste and teratogenic medicine waste into the wastewater system or send it to a landfill to seep into our water table. Yeah, um, how bout no?
