The toxicity of newsprint ink is addressed in CDFS-122. With virtually no toxic concerns of newsprint, the feasibility of use for large animals has been the topic of different studies. Mastitis is defined as inflammation of the mammary glands. When the mammary glands are infected, the teats become rigid decreasing milk quality and production. Mastitis is commonly caused by a bacterial infection.
Bacteria have different origins.
Some bacteria are normally found on animals and humans because the bacteria are necessary for everyday living. Staphylococcal bacteria are normally found on mammalian skin. Streptococcal bacteria are of fecal origin and associated with organic materials, such as corn or straw. Coliform bacteria are also of fecal origin. Klebsiella species is a specific type of coliform bacteria that was singled out in this study because its evidence in bedding is directly related to mastitis.
