During hot and humid seasons, extensive rot of sour lime was
observed to be caused by Aspergillus flavus. In view of this,
investigations were undertaken to obtain data on the production
of various toxins by A. flavus during post harvest pathogenesis
of sour lime. Sixty percent of the pathogenic A. flavus isolates
were detected to be aflatoxin B(1) producers in sour lime
tissue. It was also noted that thirty three percent of
aflatoxigenic A. flavus isolates had the potential to coproduce
cyclopiazonic acid (CPA). Such aflatoxigenic isolates produced
quantitatively more CPA (ranging from 250.0 to 2501.3 microg/kg)
than aflatoxin B(1) (ranging from 141.3 to 811.7 microg/kg) in
the affected sour lime. This study demonstrates for the first
time that sour lime are a favourable substrate for aflatoxin
B(1) and cyclopiazonic acid production by A. flavus isolates.
This is of great concern to the health of consumers.
