Potential Production of Sterigmatocystin on Country-Cured Ham

In laboratory media, 10 of 16 isolates of Aspergillus versicolor from country-cured ham were capable of producing sterigmatocystin. Three of these isolates were tested and found to produce sterigmatocystin on country-cured ham after 14 days of incubation at 20 or 28 C.
