The Iowa State University Center for Food Safety and Public Health has developed a series of biological risk management tools for beef and dairy producers. The materials are designed to increase awareness on how diseases can enter a cattle facility and spread among the animals. Risk assessment and management recommendations focus on a route of disease transmission approach, rather than focusing on specific diseases.
There are five main routes of disease transmission: aerosol, direct contact, fomite, oral and vector. With targeted practices against these five routes, producers can reduce their risk of common, everyday diseases entering their farms and ranches, as well as foreign animal or emerging diseases.
The materials are designed for cattle producers to learn about various risks, conduct self-assessments, and implement practical management steps. Visit www.cfsph.iastate.edu/BRM/beefresources.htm  for links to the various materials.
