JEFFERSON CITY, Mo. (AP) — Missouri has lifted restrictions on the movement of poultry near facilities in two counties where bird flu was confirmed last month.

The Missouri Department of Agriculture announced in a news release Thursday that the decision was made after testing showed no further spread of the highly pathogenic H5N2 strain of avian influenza. The restrictions were put in place after the disease was detected in Jasper County in the southwest part of the state and Moniteau County in mid-Missouri.

Agricultural officials urged owners to continue keeping their birds away from wild fowl and to report unusual deaths.

The virus is deadly in poultry but poses no immediate public health concern. It’s carried by wild waterfowl that aren’t sickened by it. The incubation period is about 21 days.
