Aflatoxin‐negative cottonseeds in bright, greenish yellow fluorescent seed locks

Abstract

Abstract Bright, greenish yellow (BGY) fluorescent locks were removed from an aflatoxin‐contaminated sample of lint cotton. Hand ginning of these fluorescent locks yielded 51 seeds, 26 with BGY linters, and 25 with nonfluorescent linters. All seeds were analyzed individually for aflatoxins. Two of the seeds with BGY lint accounted for 99.9% (2.75 μg) of the total aflatoxins. Four other seeds each contained 0.02 μg of total toxins, and all others contained no toxins. Our results show that 88% of the seeds necessarily lost in discarded fluorescent locks would contain no aflatoxins.
