Network Analysis of Livestock Movements (Including Poultry and Hatching Eggs) Introduced in California from 2004 to 2014: Implications for Potential Introduction and Spread of Infectious Diseases

Transmission of infectious diseases mostly occurs due to contacts among infected and susceptible individuals. Therefore, the characterization of the contact patterns among individuals is a prerequisite to better understand and even predict the spread of diseases in a population. California is one of the most important states for livestock production and trade, particularly cattle and poultry.

Investigating raccoon abundance, home range and Baylisascaris procyonis prevalence in Yosemite National Park and its association with human occupancy in Yosemite Valley

Currently, there is lack of information regarding the abundance and movements of raccoon population living in Yosemite National Park. Recently, close human-raccoon interactions have been increasingly reported in Yosemite Valley, raising concerns about zoonotic disease transmission. Moreover, due to their diet habits, raccoons may pose a challenge to reintroduction programs of endangered species into the park.

Development of an early-warning system based on real-time risk assessment, producers self-assessment of biosecurity & educational tools for the prevention, early detection & rapid control of AI outbreaks in the US poultry industry

The goal of this interdisciplinary, multi-institution, research-extension project within the "Critical Agricultural Research and Extension (CARE)" priority is to develop an innovative early-warning system for better prevention and control of Avian Influenza (AI) outbreaks in US poultry industry.

Evaluation of the Interface between Feral Pigs and Pasture-Raised Pigs, a Multi-Agency Epidemiological Approach: Implications for Infectious Disease Transmission and Surveillance

The growing niche of pasture-raised pigs in the last two decades reflects consumer demand for local, sustainable, humanely-raised meat. One of the challenges of raising pigs outdoors is the increasing probability of domestic pigs interfacing with feral pigs and a corresponding increasing risk of emerging diseases. California has one of the largest and widest distributions of feral pigs.These two parallel trends of an expanding feral pig population and a growing interest in pasture-raised pork creates a possible disease transmission link for existing pathogens harbored in feral pigs.
