Amana Refrigerator Recalls
Scientists at the University of Haifa in Israel have discovered new species of bacteria that can grow at low temperatures in the raw milk, although it is spoiling in the refrigerator. The researchers found that the microbial population in raw milk was much more complex than initially thought. Identified and described one of these bacteria, Chryseobacterium oranimense, which grows at low temperatures and secretes enzymes that are capable of spoiling the milk. Most enzymes are denatured at high temperatures of pasteurization. However, heat-stable enzymes produced by bacteria cold tolerant (can grow to 7 ยบ C), will affect the taste of milk and dairy products. Although not yet determined the impact on the quality of milk from the bacterium C. oranimense and two new species (C. haifense and C. bovis) identified, the discovery will contribute to the understanding of the physiology of these organisms and complex process in which they are involved. In Israel, the dairy companies estimate that cold-tolerant bacteria can cause a 10% loss in fat and milk proteins. Researchers have found that bacterial communities, 20% of the bacteria isolated were new species and 5% of these were members of the genus Chryseobacterium. In a large majority of EU countries, the sale of raw milk is banned (still allowed in England, Wales and Northern Ireland). There is an open debate between whether or not to take raw milk. Some think that the health benefits of extra content nutrients that raw milk outweigh the risks of eating potentially pathogenic bacteria such as Mycobacterium bovis, which causes tuberculosis and Salmonella species.
