Human Health: Pathogens and Contaminants in Livestock Systems


Human Health: Pathogens and Contaminants in Livestock Systems

View the Archive

Livestock operations take great care to maintain the health of their animals. Attention to the health of the people working with the livestock should also be a part of the day-to-day operations. Pathogens such as E.Coli 0157:H7, Salmonella, and Listeria can infect humans. Dust, whether from manure, feeding, or field operations can also impact human health. Dust is often overlooked as being just a part of agriculture, but small particulate matter (PM10 and PM2.5) can seriously impact people with respiratory issues. This webinar will provide practical guidance on reducing pathogen and inhalation exposures in livestock operations and identify ways to protect human health and those we love.

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

Presenters for this webinar include:

  • Dr. Matt Nonnenmann, University of Iowa
  • Dr. Renee Anthony,  University of Iowa
  • Dr. Michael Pate, Utah State University


Handouts (PDF format) will be available the day of the webinar at the live webinar information page. Find out more about this webinar or future webinars by the Livestock and Poultry Environmental Learning Community (LPELC).
