ADDL Staff Participate in HPAI Preparedness Exercise

Anne Parkinson, ADDL Serology Section Head

On February 15th the ADDL staff participated in a Highly Pathogenic Avian Influenza (HPAI) preparedness exercise sponsored by the Ohio Poultry Association in collaboration with the Ohio Department of Agriculture Division of Animal Health, USDA/APHIS/VS, Ohio poultry producers and the Ohio State University. The exercise was facilitated by Dr. Carol Cardona from the University of Minnesota Secure Food Team and Dr. Tom Hans, UDSA APHIS VS.


The exercise focused on the logistics of permitted movement of poultry and poultry products during a HPAI outbreak as described in the Secure Poultry Supply Plan.  The interactive outbreak scenario established control areas and participants learned how to achieve and maintain monitored premise status to qualify their products for movement during the chaos that ensues during a declared outbreak. 


The ADDL involvement included providing HPAI testing to producers to meet Ohio and USDA permitting requirements and to maintain a testing schedule that allowed a consistent flow of reported results to the regulating agencies and producers. A review of ADDL’s preparedness to assure consistency with the Secure Poultry Plan was valuable. Opportunities for improvements were identified during the exercise and updates to the ADDL emergency response plan were made to better serve the poultry industry in the event of an outbreak in Ohio.


Poultry Pathology Lecture Presented at The Ohio State University

On February 8th, Dr. Jeff Hayes presented a 2 hour lecture regarding gross and histopathologic lesions of poultry and game birds to veterinary pathology residents at the Ohio State University Department of Veterinary Biosciences.


Beef Expo - March 17-19, 2017

Anne Parkinson, ADDL Serology Section Head

Please note that new testing requirements have been put into place by the Department of Agriculture’s Division of Animal Health for this year’s Ohio Beef Expo.  New mandatory rules for trichomoniasis have been announced and require that all bulls over 12 months of age originating outside of Ohio be tested once using PCR and declared negative before entering the state.  It is also strongly recommended that bulls originating IN Ohio be tested negative for Trichomonas sp. using a single PCR test.  Any testing for the Expo needs to be completed within 30 days of the show to qualify.  The ADDL offers testing services that cover the Expo’s health requirements with results provided within 24 hours of sample receipt.  For more details about the Beef Expo’s health requirements, please refer to the Ohio Beef Expo 2017 Health Requirements. You may contact the ADDL at 614-728-6220 for further testing information.


Senecavirus A Update

Melanie Prarat, ADDL Virology Section 

The ADDL performs diagnostic investigations on any swine having vesicular lesions on its snout and/or around its coronary bands to rule out foreign animal diseases (FADs), including foot and mouth disease (FMD).  Senecavirus A (SVA, also known as Seneca Valley Virus), is a clinical differential of foot and mouth disease virus (FMDV), continues to be detected in Ohio on a weekly basis.  Most cases are found during transport or at the time of slaughter.  It is important for producers and veterinarians to continue reporting of pigs with vesicular lesions to ensure rapid detection of FADs, safeguard our agriculture, and protect the health, quality, public confidence, and marketability of our nation's livestock products.


The ADD offers virus isolation and real-time RT-qPCR to detect SVA in vesicular fluid/tissues, swabs, serum and feces.  Virus isolation can take up to 2 weeks, while  real-time RT-qPCR testing can be completed within 24 hours of sample receipt.


Aquaculture Proficiency Tests

The ADDL successfully passed its annual NAHLN Proficiency Tests for detection of infectious salmon anemia virus using RT-qPCR and detection of viral hemorrhagic septiemia virus using RT-qPCR and/or virus isolation. Aquaculture continues to be a growing industry in Ohio.
