The US Food and Drug Administration (FDA) provided the following response to the question "Would it be correct to say that the FDA states that there is no pus in milk?" in a Jan. 3, 2008 email to ProCon.org:

“[T]he types of somatic cells [cells that are present in pus but do not constitute pus in and of themselves] in milk are of several different types, including epithelial. Pasteurized milk produced under the requirements of the Pasteurized Milk Ordinance is safe to consume. The agency has no evidence that supports milk in US commerce is inherently unsafe, dirty or not sanitary. If you wish to offer safety data, risk analyses, or material information to the agency, please do. If you have additional concerns, please let us know. We will make every effort to address them.”

[Editor’s Note: ProCon.org responded on Jan. 4, 2008 to the above FDA e-mail. We asked the FDA to please provide a direct response to our question: Would it be correct to say that the FDA states that there is no pus in milk? ProCon.org contacted the FDA again with the same question on Feb. 25, 2008 and again on Aug. 30, 2009. We have not received a response.] Jan. 3, 2008
