The lipolytic activity of some of the major psychrophilic bacterial population of chicken meat and liver available in the local market was seem to responsible not only for loss of flavor but also for production of certain toxic substances like 7-(2-hydroxyethyl)-monascorubramine, a red pigment produced by certain Penicillium sp.
