Russia has expanded its ban on US poultry imports to include most poultry and poultry products from Maryland after an outbreak of bird flu there.

The Russian agriculture ministry said the ban includes live birds, hatching eggs, poultry meat and all poultry products that have not undergone heat treatment, as well as poultry feed, reported Reuters.

Russia has already placed similar bans on poultry from Texas and Delaware after bird flu outbreaks.

Agriculture Minister Alexei Gordeyev has said Russia could consider banning all imports of US poultry if the outbreaks are not contained.
