ENVIRONMENTAL MICROBIOLOGY

NANCY HALL: nancy-hall@uiowa.edu

DNA fingerprinting was used to detect Clostridium perfringens in taco meat served at a high school staff luncheon.

The Environmental Microbiology section provides analytical services to detect potentially harmful microorganisms in many environmental matrices, including food and water. Such analyses are used in outbreak investigations to pinpoint the source of contamination and to assess the environmental impact from exposure to microbial contaminants. Culture confirmation of microorganisms is critical in the performance of DNA fingerprinting on the food, environmental and clinical stool isolates to evaluate the scope of the outbreak — local or national — and focus remediation efforts.

Laboratory testing is also provided in support of statewide water surveillance programs to assess the overall safety of public and private drinking water supplies, surface waters (lakes and ponds), and recreational waters (pools and spas). Pathogen analyses of water, food and environmental samples are expanding with emphasis on Cryptosporidium, Legionella, Salmonella and Listeria.
