http://dx.doi.org/10.1021/jf0114482"Honey. Taking
into account the maximum quantities of honeys eaten (up to 93
g per day for some adult consumers and 32 g per day for infants;
see below), even at the highest level of pyrrolizidine alkaloids
thus far found in honey, acute pyrrolizidine alkaloid poisoning
is an unlikely outcome for most consumers of honey (1).
However, levels of pyrrolizidine alkaloids present in honeys
from pyrrolizidine alkaloid-containing plants are well above that
considered by the German Federal Health Bureau (17) to be
capable of causing progressive chronic toxicity, especially in
infants and fetuses."
