科学家发现病毒可以减少牛奶中食物传播的疾病,但成本仍然是一个障碍。 Scientist finds viruses can reduce foodborne illnesses in milk but cost remains a barrier.

食物微生物学家Dennis D'Amico发现,细菌病毒感染细菌,可以大大减少食用病原体,如消毒牛奶中的Listeria和Salmonella病原体。 Food microbiologist Dennis D'Amico found that bacteriophages, viruses that infect bacteria, can significantly reduce foodborne pathogens like Listeria and Salmonella in pasteurized milk. 在原奶中,菌体减少了沙门氏菌,但没有减少李斯特菌或大肠杆菌. In raw milk, phages reduced Salmonella but not Listeria or E. coli. 奶酪生产限制了它们的有效性。 Cheese-making limited their effectiveness. 主要障碍是成本;需要的噬菌体是病原体的一百万倍才能获得结果。 The main hurdle is cost; a million times more phages than pathogens are needed for results.
