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.
