More honey bees dying, even as antibiotic use halves
Despite tighter restrictions on antibiotics used in Canadian beekeeping, honey bee death rates are still rising. A new study led by University of Guelph researchers, published in Nature Sustainability, is the first large-scale project to assess antibiotic usage trends and their impact on honey bee health in Canada. The withdrawal of antibiotics, following recent regulation changes, was one of the top predictors of honey bee overwintering mortality — a result that surprised lead author Dr. Bren
