Cutting Through the Propaganda on Raw Milk and Brucellosis

Various media have been waging one of the bigger anti-raw milk propaganda campaigns in memory through their reporting on a recent individual case of brucellosis attributed to raw milk consumption. The media are using the case of the third individual incidence of brucellosis blamed on raw milk consumption in the past year and a half to warn the public that people are putting their health in jeopardy if they don’t consume milk that is pasteurized. The illnesses occurred in Texas in August 2017, New Jersey in October 2017 and New York in November 2018 with the latest illness blamed on Miller’s Biodiversity Farm of Quarryville, Pennsylvania; there is currently a quarantine in effect prohibiting the farm from distributing raw dairy products. A cow that tested positive for Brucella has been removed from the dairy herd.

The media have been taking their cues from press releases issued by public health departments that have been giving the advice to pasteurize all milk. However, the solution to avoid getting brucellosis is far different from what public health and the media are telling you. In the words of one healthcare professional, “For public health officials to issue public notices that the solution to this avoidable problem is to pasteurize all milk, is astonishing.”

First off, the three cases of brucellosis are the only known cases attributed to raw milk consumption over the past 20 years. Brucellosis is a systemic disease in cattle and humans that is caused by the bacteria Brucella abortus. At one time the disease in cows caused severe reductions in offspring and was a problem for the cattle industry. A national eradication campaign was launched in the 1950s and, according to USDA statistics, the number of cattle/bison herds affected by brucellosis in the U.S. has been less than 10 every year from 2003 onward.1

The eradication program’s success has led to a huge decline in the number of brucellosis cases in humans; estimates are that there are about 100 cases of human brucellosis per year in this country.2 In the U.S. this is mainly an occupational disease with most of the rare cases of brucellosis being in people who attended the birth of an infected cow and then became infected during handling of the birth tissues and fluids.3,4

In an infected dairy cow, the Brucella abortus pathogen can proliferate in the mammary glands and then enter the milk. The pathogen can pass to humans when drinking the infected milk but, as mentioned, the cases of brucellosis (also known as undulant fever) attributed to drinking raw milk in the U.S. are extremely rare.

The “milk ring test” is the traditional and commonly used method to screen dairy herds to detect any cows with brucellosis; the test is performed on the herd’s milk to check for the rare presence of Brucella antibodies.

Two vaccines against brucellosis have been developed for calves: the S19 vaccine and the RB51 vaccine. The S19 vaccine is effective but it has the disadvantage of causing testing for antibodies to become positive. The vaccine can make it difficult to distinguish between a vaccinated cow and an infected cow. The RB51 vaccine does not cause the antibody testing of cows to become positive but another problem arises with its use.

The RB51 vaccine must be administered to calves before they become fertile; a side effect is that, if a cow is given the RB51 vaccine when pregnant, it may actually cause an infection with the vaccine strain of Brucella in the vaccinated cow. It is, therefore, possible that if the RB51 vaccine isn’t given strictly according to the protocol, the vaccinated cow may become infected and may shed the pathogen (i.e., the RB51 strain of Brucella) into the milk.

Public health officials have found in all three cases of illness from brucellosis attributed to raw milk consumption, the strain of Brucella abortus discovered in the three individuals was the RB51 vaccine strain. In fact, in November 2017, the Pennsylvania Department of Agriculture sent a letter to licensed raw milk producers in the state advising them to stop immunizing cows from brucellosis with the RB51 vaccine.5

So the solution to preventing brucellosis in raw milk is not for producers to pasteurize the milk but rather to either stop giving their herd the RB51 vaccine or to make sure their vets give the calves the vaccine before the calves become fertile. Worth noting, too, is that hundreds of people drank raw milk produced by the herds responsible for the three cases of brucellosis and, as far as is known, no one else became sick.

In the meantime, the media fear-mongering continues on. The latest case of brucellosis attributed to raw milk consumption dates back to November 2018, but to read the stories in the media, you would have thought it was just discovered. CDC press releases on this latest case dated January 23, 2019, and February 11, 2019, are providing the impetus for the flood of media reports.

Has an agenda ever gotten so much mileage over three illnesses?

A fear-inciting statement from the February 11 CDC press release that the media have parroted is, “the CDC and state health officials are investigating potential exposures, to Brucella strain RB51 in 19 states, connected to consuming raw (unpasteurized) milk from Miller’s Biodiversity Farm in Quarryville, Pennsylvania.”6 (The farm allegedly distributed raw milk to people in the 19 states listed later in the release.) Being exposed to a pathogen is far different than being sickened by it; we are exposed to various pathogenic bacteria such as listeria and e. coli in the environment every day.

One headline screamed, “Deadly Disease Caused by Raw Milk Has Already Put 19 U.S. States on High Alert.”7 There have been no deaths from brucellosis attributed to raw milk consumption since the eradication program succeeded in substantially eliminating the incidence of the disease and possibly even long before then.

The public health agencies and their allies in the press have been misleading the public long enough on raw milk and brucellosis. It’s time for fear and hysteria to give way to science and common sense.

Raw Milk Dairy Under Investigation

CDC accuses Millers Organic Farm of causing raw milk illness

CDC accuses Millers Organic Farm of causing raw milk illness

A Pennsylvania Raw Milk Dairy Under Investigation by government agencies?

The raw milk dairy under investigation is Miller’s Organic Farm in Pennsylvania, which we wrote about several weeks ago when the CDC accused them of causing illness in 2 people.

David Gumpert has been uncovering additional facts in the case agains this raw milk dairy and reporting about it on his blog.

In his most recent article, he states

“If owner Amos Miller fails to allow inspection of his facilities by the deadline, the U.S. Justice Department “will be forced to initiate enforcement proceedings,” it said in a recent letter to the Pennsylvania farmer. While the Justice Department didn’t say exactly what it plans, presumably it will seek either an injunction of some kind, or a similar action, which would ostensibly restrict sales of Miller’s food and impose severe fines or raids for violation of a court order.”

“Regardless of which agency takes the legal lead, the government’s intent is to challenge Miller’s on the basis of safety rather than the legitimacy of private food distribution. Government lawyers know that it will be much easier to convince a judge to enforce an injunction or similar legal device based on fear-mongering than on the legal aspects of private membership associations.”

Since Miller’s Organic Farm operates as a private membership association so that others can enjoy the raw milk and other raw dairy products, this is an important case to watch. When the FDA, USDA or state level agencies target one farm for “enforcement,” they are effectively targeting all who want access to nutrient dense and healing foods. Including and most especially fresh raw milk from grassfed cows.

An email address is set up to collect testimonials about products from Miller’s Organic Farm and all letters of support. Send emails to WriteToMillers@gmail.com

For a virtual tour of the farm and the family who operates it, see the recent post on Nourishing Liberty about Miller’s Organic Farm

We will continue to update this situation as it changes.
