Coliforms, a common form of bacteria, have been an indicator of the presence of pathogens in assessing the contamination of water as well as dairy products [10]. Coliforms can cause rapid spoilage in milk because they ferment lactose with the production of acid and gas, and

Fungi in partic-ular produce an abundance of extracellular pectinases and hemicellulases that are important factors for fungal spoilage (Miedes & Lorences, 2004). Some spoilage
