(CNN) North Carolina's poultry farms suffered significant losses in Hurricane Florence, while flooding from the storm damaged crops in South Carolina, industry officials said this week.

Some 3.4 million poultry birds were killed in North Carolina, according to the state Department of Agriculture & Consumer Services. That exceeds poultry losses two years ago in Hurricane Matthew, it said.

The state last year tallied about 830 million head of broiler chickens, plus 32 million head of turkeys, a federal inventory shows.

Sanderson Farms, one of the largest poultry producers in North Carolina, lost 1.7 million chickens on its farms, and 60 of its 880 production chicken broiler houses have flooded, the company said in a news release

In addition, about 30 Sanderson farms that together house more than 6 million chickens around hard-hit Lumberton, North Carolina, remain isolated by floodwater and out of reach of feed trucks, Sanderson said, noting that the number of dead chickens could increase.
