contamination – Swine in Minnesota

Assessment of PEDV Trailer Contamination at the Harvest Facility

Today we bring you a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

University of Minnesota researchers Lucas Ferreira, Mark Schwartz, Marie Culhane, and Cesar A. Corzo share preliminary results from their ongoing study examining trailer contamination at the harvest facility during unloading.

Environmental contamination assessment in farms undergoing an outbreak with PRRS 1-4-4 Lineage 1C

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

The Morrison Swine Health Monitoring Project take a look at whether PRRSv cases associated with the linage 1C, RFLP 1-4-4 variant can be detected in the outside areas of farms undergoing an outbreak.

Key Points

There is little understanding of contributing factors aiding the 1-4-4 L1C PRRSv rapid transmission and biosecurity breaches
Environmental detection in recently infected farms was possible although detection was low
Most positive samples originated from exhausting fans, showing the virus may exit a positive barn via that route
