African swine fever virus DNA detection in commercial pig feed and feed
ingredients in China
Abstract
During the acute phase of the African Swine Fever Virus (ASFV) epidemic
in China, complete feed, and feed ingredients from three mills were
tested for ASFV DNA by PCR. Across mills, the percentage of positive
sample pools detected in complete feed ranged from 0.5% to 1.2%, and
from 0.2% to 1.8% in feed ingredients, including positive pools of
wheat, rice, corn, and soy samples. This is the first report of ASFV
contamination in feed under commercial conditions in China.
