Detection and identification of Penicillium spp. in a frozen chicken nuggets production facility.

Frozen chicken nuggets can be stored over a long period, during which time they may be exposed to temperature abuse conditions leading to spoilage by psychrophilic filamentous fungi. The purpose of this study was to investigate the main sources of chicken nugget spoilage. Mycological analyses were performed using raw materials and products from each stage of processing, as well as from the industry's indoor air environment.
