Abstract - Bee colonies were dosed with chloramphenicol (CAP) 1.0 g per hive
(single dose in sucrose solution). Samples of honey were
then collected at intervals over a 48-week period and samples of royal
jelly, beeswax, honeybees and brood collected at intervals over a 12 week
period. The mean concentration of CAP in the honey at 7 days after dosing
was 26 g/g, declining to 1.0
g/g at 332 days. Application of the
shook swarm procedure resulted in a mean concentration of CAP in honey of 26
g/g at 7 days, declining to 0.1
g/g at 332 days. The mean concentration of CAP in non-honey samples was in the range of 0.5 to 6.8
g/g, and 0.2 to 3.3
g/g at 7 days and 56 days, respectively.
These results indicate that use of CAP can be detected up to 332 days after
dosing even if the shook swarm procedure is used in an attempt to clean the
hives. There was no evidence of any significant formation of bound
CAP-glucose conjugates in honey.
