Thanks to Mark Patterson from the London Beekeepers Association for posting about this – bee expert Professor Dave Goulson featured in a segment about pesticides in honey on the BBC show Food: Truth or Scare last Wednesday (available to UK viewers for another 22 days).
The honey segment starts at 21 minutes in. The presenters, Chris Bavin and Gloria Hunniford, look at headlines from last autumn about pesticides found in honey – “75% of honey we eat contains pesticides” reads one, quoting a study in which scientists tested 198 honeys from around the world. “I always regard honey as being pure, about being healthy, about being mending” says a shocked Gloria.
“Do we need to worry about the honey we eat?”, Chris chirpily asks Prof. Goulson. Together they look at an observation hive and we hear that honey bees travel up to five miles to forage, meaning they inevitably come into contact with pesticides. It’s also explained that many UK supermarket honeys contain honey blended from several different countries, often a mix of EU and non-EU honeys. Even organic honey producers cannot guarantee their honey is pesticide-free – certainly in the UK there is no organic farm big enough to provide over a five mile radius of pesticide-free forage.
However, Dave tells us that the good news is that the levels of pesticides found in honey are small – the concentrations are low and well beneath what are deemed to be safe levels for humans (in the short term!). There are concerns about the possible long-term effects of pesticides on us – no-one really knows for sure what the effects might be. However, Dave is going to carry on eating honey – phew! Not a surprising conclusion but a reminder of the environment our bees have to contend with.
- Nerve agents in honey (Science, 06/10/17) – “On page 109 of this issue, Mitchell et al. (2) show that most honeys sampled from around the world between 2012 and 2016 contain neonicotinoids at levels known to be neuroactive in bees.” The full-text is not available without a subscription but there is a freely available accompanying short video for the research, Pesticides found in honey around the world.
