Bioaerosols from Feedlots and Dairy Farm Operations

Concentrated animal feeding operations can create large amounts of aerosols, comprised of dust, odors, and biological particles. Dairy and feedlot operations can generate these aerosols during both waste application and animal activity throughout the day. It is well known that bacteria and endotoxin can travel over large distances given certain conditions; however it is also well known that the air environment is an extremely harsh environment for bacteria. Aerosolized bacteria and endotoxin released from feedlot and dairy operations potentially pose a risk to the occupationally exposed as well as the general public. This webinar will focus on research at two locations where aerosolized bacteria and endotoxin are being measured from dairy and feedlot operations. The listener will take away an understanding of the processes behind aerosol generation, levels of bacteria and endotoxin in the air surrounding these operations, and potential issues associated with exposure to the public.

An application for continuing education credit for Certified Crop Advisors (CCAs) and members of the American Registry of Professional Animal Scientists (ARPAS) has been submitted.
