Good Practice Crucial to Prevent Bee Disease, says SAC

A bee expert from SAC (Scottish Agricultural College) is warning beekeepers to remain vigilant to prevent the further spread of the bee disease Nosema ceranae, after confirmation of Scotland’s first ever cases was announced last week.

Following the news from Science and Advice for Scottish Agriculture (SASA) of the three confirmed cases, SAC bee advisory officer Graeme Sharpe says beekeepers should ensure they recognise the signs of Nosema ceranae so it can be treated promptly.

The key sign to look out for is soiling inside and on the front of a hive. Graeme also echoes SASA’s advice that good husbandry practices, such as sterilising or replacing the comb, are vital in preventing the further spread of the disease.

Graeme said: "It was really inevitable that Nosema ceranae would be confirmed in Scotland sooner or later, given that many cases have already been recorded in England, Wales and Northern Ireland.

"While the disease does not pose a risk to human health or to honey quality or safety, it is vital that it is prevented from spreading if we are to avoid the further decline of the honeybee.

"The disease shortens bees’ lifespan by affecting their digestion. There is a seasonal trend to infection, with low levels during summer, a small peak during autumn and a slow rise in infection in winter.

"In the early spring, levels of infection increase rapidly when brood-rearing starts and flight is limited due to low temperatures."

Any beekeeper who suspects their colony is affected by Nosema ceranae can contact Graeme for advice at SAC’s Ayr Disease Surveillance Centre on 01292 520318, or speak to SASA.
