Nebraska defines Regulated Medical Waste as: A waste or reusable material known to contain or suspected of containing an infectious substance including:

• Waste generated in the research, diagnosis, treatment, or immunization of human beings or animals
• The production or testing of biological products
• Cultures and stocks of infectious agents and associated biologicals
• Pathological waste
• Sharps that have been used in animal or human patient care
• Contaminated animal carcasses, body parts, and bedding of animals that were known to have been exposed to infectious agents during research.

Nevada regulations do not require treatment of medical waste. Disposal in a permitted landfill according to approved practices is acceptable.

However, until the waste has been either treated or disposed, it must be stored and collected according to the requirements of Nevada Administrative Code (NAC) 444.662. (Note: the Washoe County District Health Dept. has infectious waste regulations that do require treatment before disposal.)
 
There is no comprehensive federal regulatory program for the management of medical waste. The US Occupational Safety and Health Administration (OSHA) has adopted regulations to limit workers' occupational exposure to blood and other body fluids which may pose a risk of infection by bloodborne pathogens.

Medical wastes must be stored in watertight and clearly labeled containers, that are resistant to corrosion in a safe location that is inaccessible to the public. They must be in cleanable containers with liners or in a manner approved by the solid waste management authority.
