Geektastic: I'm sure someone can explain how a traveller eating honey on their morning toast affects bees.
In a few short words that they'll accept and believe - I kind of doubt it. One risk:
In experiments carried out early in the 20th century, M. pluton was shown to survive for about 12
months in an incubator and at normal room and outdoor temperatures. In honey exposed to direct
sunlight the organism was destroyed after 3-4 hours, while in honey stored away from direct
sunlight the organism survived up to 7 months (White 1920).
In view of the above, M. pluton is classified as a potential hazard in imported honey.
TLDR. If you have some imported honey from a hive which was infected with EFB (european foul brood), then if a local bee eats any of that honey - quite likely as they're inclined to be attracted to honey, then they'll take that back to their hive, and you'll have introduced a new disease to NZ which would be destructive to our local industry.
Yes, I understand that the honey may contain things. It just seems a bit unlikely a bee will pop into a house, open the honey and eat it.
I wonder what they would say if you bought NZ honey back from overseas in sealed jars! ;-)
I'm not terribly likely to bring any myself (aside from knowing you aren't allowed to) as we currently have 28 beehives on the property, so honey is not something we tend to run short of as the keeper pays his 'rent' in honey and I would have to eat almost nothing else to stand much chance of getting through it all.
