CALGARY - Alberta provincial apiarist Doug Colter said an increasing incidence of American foul brood is beginning to be found in the Canadian province.

Analysis of samples from hives sent in by 28 Alberta beekeepers found evidence of AFB in eight that it's becoming resistant to the current antibiotic treatment.

"I'm afraid this fall when I start inspecting colonies it will be just the tip of the iceberg," he said.

The eight samples came from beekeepers with a combined 26,000 hives - 15 percent of Alberta's total.
