The CAHFS San Bernardino branch served as the central entry point for birds that were necropsied on-site and for samples that were shipped to the USDA National Veterinary Services Laboratory and the Davis CAHFS lab for testing for the presence of the causal virus.
The CAHFS lab in San Bernardino was instrumental in the diagnosis and eradication efforts during the 2002-2003 outbreak of exotic Newcastle disease, which was originally diagnosed in a backyard chicken.
Researchers within the UC system target bluetongue in a collaborative effort involving individuals at SVM, UCCE, UC Riverside, CDFA, CAHFS, USDA, and also local veterinarians and local cattle and sheep producers.
The CAHFS laboratory system then confirms these observations with laboratory findings.
Recently, the CAHFS laboratory database of toxicological findings was mined for use in a UCCE publication on poisonous plants in California (Forero et al.
The CAHFS laboratory system and UCCE also play an important role in poultry diseases.
The county distribution data demonstrated a substantial increase in submissions in certain counties; however, there is a potential for bias in these results due to a variation in the ease of making a submission close to a CAHFS laboratory.
6% of all SDs from backyard poultry throughout the CAHFS laboratories in the past 10 years.
CAHFS and UC Cooperative Extension faculty routinely give public talks during related community events such as the Davis Tour de Cluck or the Heirloom Exposition in an effort to improve outreach.
After the END outbreak of 2002-2003, a study showed that fewer than 2% of backyard poultry owners interviewed were aware of the CAHFS Backyard Flock program and had submitted birds for testing (Soberano et al.
The estimated cost to CAHFS, and ultimately to CDFA, for performing each necropsy averages $172 (Emily Sanson-Smith, CAHFS Davis, personal communication).
We would like to thank CAHFS systemwide for their combined efforts in the Backyard Flock program, and Lucy Gomes, CAHFS Tulare IS staff, who was responsible for extracting the data for this study.
