SUNNYSIDE, WA (AP) — Officials say the more than 1,800 dairy cows that died in a blizzard in southern Washington state earlier this month were a nearly $4 million loss, not including the lost milk production.

Farm Service Agency program specialist Gerri Richter says seven dairy farms have given notices of loss to the agency’s office in Yakima, and more are expected to report soon.

The state dairy federation, says up to 15 farms near Sunnyside lost cows, with one dairy reported to have lost about 600 cows in the Feb. 9 storm.
