Groundnuts—Presence of Anatoxin.—In Britain, during 1960,
a large number of turkeys died from an unknown cause. Investigations
revealed that they had been fed on a groundnut meal
which contained a toxic factor arising from a mould Aspergillus
flavus and this has been named Aflatoxin. Young animals were also
found to be susceptible to the toxin.
The presence of Aflatoxin appears to develop after the nuts
have been lifted and seems to be proportional to the discolouration,
amount of damage to the shell and speed of drying. Aflatoxin also
