title: Ochratoxin a in retail flour.
abstract: Flour delivered to a school in the Bournemouth area was found by thinlayered chromatography to contain up to 6.25 mg/dg of ochratoxin. A. Penicillium cyclopium, a fungus known to produce this toxin, was found in discoloured portions of the caked flour. Ochratoxin was also found in a second sack delivered to the school, but not in samples of sound flour or in six samples of flour of varying quality from other sources. The health risk did not appear to be serious.
