David Krause, PhD, MSPH, CIH, FAIHA - Remediation of Microbial Contamination & Legionella

This week we welcomed Dr. David Krause for a discussion on remediation of microbial contamination and Legionella. We have wanted to get Dr. Krause on the show for a long time now and the stars have lined up.

Dr. David Krause is the founder of Healthcare Consulting and Contracting (HC3). He is a Certified Industrial Hygienist and Toxicologist, with 30 years of experience in public health, occupational hazard assessments, and indoor air quality. David received his Doctorate in Environmental and Occupational Health and Master of Science in Public Health Toxicology from the University of South Florida, College of Public Health in Tampa, FL. He is a nationally recognized expert in risk assessment, workplace exposures to pathogens and hazardous chemicals, health care facilities, Legionnaires’ disease, combustion products, flame retardants, indoor air quality, and mold. From 2008 to 2011 Dr. Krause served as the State Toxicologist for the Florida Department of Health.

During his tenure as State Toxicologist Dr. Krause led state-wide investigations into the potential health effects of corrosive emissions from Chinese Drywall, sources of carcinogens in the Acreages Pediatric Cancer Cluster, and human health risks throughout the Deep Water Horizon oil spill response. Dr. Krause reviewed and approved all of the state’s ATSDR program health hazard evaluations and fish and seafood consumption advisories. Florida’s fish and seafood consumption advisories considered human health risks due to mercury and polychlorinated biphenyls (PCBs). Developing health advisory levels for chemicals in drinking water and human health screening levels for petroleum products and PAHs in coastal waters and beach sediments were among the responsibilities of Dr. Krause while serving as the State Toxicologist.

In 2009 he co-authored the Guidelines for the Surveillance, Investigation, and Control of Legionnaires’ Disease in Florida. As a volunteer for the American Industrial Hygiene Association Dr. Krause co-authored and edited the AIHA Guideline for the Recognition, Evaluation, and Control of Legionella in Building Water Systems, in 2015 and the 2nd edition in 2022.

David is a member of the ACGIH Bioaerosols Committee and was a contributing author for the ACGIH 2021 White Paper on Engineering Controls for Bioaerosols in Non-Industrial/Non-Healthcare Settings. Dr. Krause is past chair of the AIHA Indoor Environmental Quality Committee and coordinated AIHA’s efforts to develop guidance on reducing the risk of spreading COVID-19 in the workplace through engineering controls and effective cleaning & disinfection.
