(March 31, 4:30 p.m.) A major shipper of organic mushrooms to several Canadian provinces is out of commission after a fire destroyed its growing facility.

And a fire at another mushroom farm in Canada put a dent in production of conventional product shipping to Edmonton and other Canadian cities.

But because of an oversupply of mushrooms in Canada, the effect on markets could be minimal.

A fire March 13 destroyed the 40,000-square-foot operation of Golden Valley Mushrooms Ltd., Pitt Meadows, British Columbia, which had shipped about 3,000 pounds of organic oyster and baby oyster mushrooms to customers in British Columbia, Alberta and Quebec, said Tony Chan, the company’s manager.

The company shipped very little product to the U.S., Chan said.

The company will need a new facility to replace the one damaged by the fire. The cause of the fire remained unknown as of March 28, Chan said.

Chan did not know when construction of a new facility could begin.

Golden Valley ships product under the Golden Valley label, Chan said.

The second fire occurred March 21 at Prairie Mushrooms Ltd., Sherwood Park, Alberta.

The fire destroyed the company’s primary growing building, cutting its supplies by 70% to 75%, according to an article in the Edmonton Sun.

Prairie is expected to ship about 100,000 fewer pounds per week because of the fire, and could take 12-18 months to rebuild, according to the story.

The fires came at a time when some Canadian producers of mushrooms were shipping more product than usual to the U.S. because of an oversupply north of the border, said Joe Caldwell, vice president of Watsonville, Calif.-based Monterey Mushrooms Inc.

Monterey does not expect its Canadian exports to increase to fill possible gaps created by the Golden Valley and Prairie fires, Caldwell said.
