The Swine Health Information Center’s (SHIC) December Domestic Swine Disease Monitoring Report is available.
This month’s Domestic Swine Disease Monitoring Report provides information about the highest positivity of PRRSV in the wean-to-market category (50%) since November 2018. This positivity was mainly driven by the PRRSV lineage 1C.5, which had a record number of detections (n=403) within a single month since its emergence. Also, the detection of this lineage broke the 2023 record by 281 cases, with 2,765 detections to date. PEDV positivity increased in November for Iowa, Oklahoma, Minnesota, and Missouri. Influenza A virus positivity increased in sow farms, reaching 36% of positive submissions overall. Mycoplasma hyopneumoniae had a decrease in the wean-to-finish positivity (25%) but remains high compared with previous years. In the confirmed tissue diagnosis, there were alarms for increased PRRSV, influenza A virus, Pasteurella multocida, Streptococcus suis, and Mycoplasma hyorhinis.
The podcast broadcasts a talk with Dr. Daniel Boykin (Smithfield Foods) about endemic pathogen activity in the US and biosecurity tips for PEDV and PRRSV.
