If pollen is taken by bees from poisonous plants such as hemlock or foxgloves, will the honey be poisonous?

Yes, although the toxin must be present in the nectar. Rhododendron and Kalmia nectars produce toxic honey, for instance, as do honey from many other members of the Ericaceae like Ledum. Coriaria and Aesculus are other plants with toxic nectars that can give rise to toxic honey.

Bees make honey from the nectar extracted from a flower not its pollen. The way toxins in nectar influences a honeybee’s willingness to eat floral nectar has been investigated by a team led by Dr Geraldine Wright (Newcastle University).


Honeybees were found to be endowed with the ability of making a connection between almost any color, shape, texture or scent with food.


The new analysis on the honeybee genome has showed that honeybees have relatively few genes for taste receptors compared to other evolved insects of a similar size like those from the Diptera Order (which includes flies and mosquitoes).


That's why researchers have thought that perhaps honeybees had a decreased need to track down and learn about toxins, even if some floral nectar is toxic.


But the new research carried out by Wright's team points out that honeybees could have the ability to detect the toxins, even if they are not able to taste them.


The team discovered that both the carbohydrates level and the toxin presence in nectar influenced a honeybee’s memory for learned odors.


Honeybees learned not to react to odors linked with toxins within 20 min of ingesting toxins, and this behavior will be kept up to 24 hours after the first contact with a toxin.
Reply:No. Only certain parts of those plants are toxic. Think about it: if the nectar in their flowers were toxic, how would the bees be able to gather it , and incidentally, pollinate 'em, without dying?

Reply:yeah, (in response to above), you mean isnt ALLAH and his creations wonderful?
Reply:No.


Bees process it before it is harmful to us.


Isn't creation wonderful?
