What’s In Your Milk?

An Exposé of Industry and Government Cover-Up on the DANGERS

of the Genetically Engineered (rBGH) Milk You’re Drinking

Introduction by Ben Cohen, Co-founder of Ben & Jerry’s Ice Cream

Foreword by Jeffrey M. Smith, author of the bestseller Seeds of Deception


A powerful exposé of the dangers of Monsanto’s genetically engineered (rBGH) milk,

and its no-holds-barred conspiracy to suppress this information.


rBGH (recombinant Bovine Growth Hormone) is a genetically engineered, potent variant

of the natural growth hormone produced by cows. Manufactured by Monsanto, it is sold to

dairy farmers under the trade name POSILAC. Injection of this hormone forces cows to

increase their milk production by about 10%.


Monsanto, supported by the Food and Drug Administration (FDA), insists that rBGH milk

is indistinguishable from natural milk, and that it is safe for consumers. This is blatantly false:

  • rBGH makes cows sick.  Monsanto has been forced to admit to about 20 toxic effects,

including mastitis, on its POSILAC label.

  • rBGH milk is contaminated by pus, due to the mastitis commonly induced by rBGH,

and antibiotics used to treat the mastitis.

  • rBGH milk is chemically and nutritionally different than natural milk.
  • rBGH milk is contaminated with rBGH, traces of which are absorbed through the gut.
  • rBGH milk is supercharged with high levels of a natural growth factor (IGF-1), which

is readily absorbed through the gut.

  • Excess levels of IGF-1 have been incriminated as a cause of breast, colon, and

prostate cancers.

  • IGF-1 blocks natural defense mechanisms against early submicroscopic cancers.
  • rBGH factory farms pose a major threat to the viability of small dairy farms.
  • rBGH enriches Monsanto, while posing dangers, without any benefits, to consumers,

especially in view of the current national surplus of milk.

The risks of cancer to consumers and particularly their children, especially those enrolled in the

Public School Lunch Program, are undisputable.

The book is a unique resource on rBGH milk. It presents Dr. Epstein’s trailblazing scientific

publications since 1989, which have played a major role in influencing other nations, including all

of Europe, Canada, Australia, New Zealand, and Japan to ban rBGH milk. The book also presents:

the author’s editorials and letters to major newspapers, and correspondence with the FDA,

Congressman John Conyers, and other key members of Congress and the Senate.

Epstein also details evidence of interlocking conflicts of interest between Monsanto and the

White House, regulatory agencies, and the American Medical Association and American Cancer

Society. He also details evidence of Monsanto’s white collar crime; the suppression and

manipulation of information on the veterinary and public health dangers of rBGH milk; and

evidence of Monsanto’s “Hit Squad,” which attempted to stifle and discredit him.

Of compelling interest is the story behind Fox Television’s firing of Jane Akre, a veteran journalist,

following her in-depth interview on rBGH with Dr. Epstein, his subsequent day-long deposition

by Monsanto on her behalf, her subsequent litigation against Fox, and Fox’s successful counter suit.

Monsanto’s corporate recklessness, compounded by FDA’s complicity and refusal to require

labeling of rBGH milk, more than justify the rejection of any assurances of its safety. Of further

interest is the critical relevance of this information to the ongoing growing concerns and debate

on genetically engineered foods, including irrefutable evidence discrediting the “trust us”

safety assurances of Monsanto, and other industries.   

The book also presents resource materials, including listings of national and international

anti-biotech, public health, veterinary and animal rights activist groups. Also listed are rBGH-free

U.S. dairy producers, such as Horizon Organic, and Swiss Valley Farms.

What’s In Your Milk’s (2006) critical message to consumers is




As evidenced in his new book What's In Your Milk?, Dr. Samuel Epstein has again made a very persuasive and important case about hidden dangers in every day consumer products.  And not only does Epstein raise our awareness about possible carcinogens in our milk supply, but also about how special corporate interests seek to keep the public in the dark about documentation relating to health hazards of their products. 

The book is a must read for every American consumer.

-Rep. John Conyers

Ranking Democrat

House Judiciary Committee

As one of the world's leading scientific authorities on genetically engineered rBGH milk, Dr. Epstein is uniquely qualified to address the hidden dangers in your milk.  His new book, What's In Your Milk? is a powerful resource to help understand how you could unknowingly increase your own and family's risk for breast, colon and prostate cancer by drinking commercial milk that is tainted with a potentially dangerous hormone.

Do yourself a favor and read this book.

-Dr. Joseph Mercola

Founder of the world's most visited natural health site,

A clear indictment of Monsanto and U.S. regulatory agencies for recklessly allowing rBGH milk, and other genetically engineered foods and ingredients, to be force-fed to consumers without any label warnings.  This is all the more serious for rBGH milk in view of the solid scientific evidence on its dangers, documented in Dr. Epstein's new book.

Indispensable reading for food activists, and for the general public.

-Ronnie Cummins

National Director, Organic Consumers Association

With the collusion of government, pathologically self-interested corporations, typified by Monsanto, continue to deceive the public on issues vital to our lives and health.  In highly readable prose, Dr. Samuel Epstein lays bare the facts, and tells us what we can do about it.

-Mark Achbar

Executive Producer and Co-Director, The Corporation

Legendary public interest scientist Dr. Samuel Epstein tells the outrageous story of how Monsanto forced its dangerous hormone drug rBGH into your family's milk through junk science, political influence, media intimidation and deceptive spin.  Here's what was done, and is being done, to you by Monsanto and what you can do about it.

Got milk?  Then get this book.

-John Stauber

author of Trust Us, We're Experts, and Toxic Sludge Is Good For You!

In the nearly 40 years since Epstein and I have been close friends, his life and work have been an epic of superb science, matched only by relentless and skilled activism.  Epstein's new rBGH milk book is the latest affirmation of these unique qualities.  It should help put a nail in the coffin of genetically engineered milk and food.

-Edward Goldsmith

Founding Editor, The Ecologist

Timely and pertinent, What's In Your Milk? is the most comprehensive review of the dairy industry's plunge into the darkness of bio-engineering of what we drink and eat.  Epstein describes a massive international experiment including hundreds of millions of adults and children as unknowing suspects.  The book's documentation of the cancer and other risks of rBGH milk make a compelling case for recognition of the role of public interest science in protecting the public interest.

-Quentin D. Young, M.D.

Chairman, Health and Medicine Policy Research Group

Since the mid-1980's, Dr. Samuel Epstein has done more than any other individual to track the shady and questionable co-mingling of government and the big milk money of the dairy industry.  Now in his latest effort, What's In Your Milk?, Dr. Epstein provides a complete history of the approval process of the controversial rBGH dairy hormone, done without the public's knowledge or consent.  With internal documents in hand, he traces two decades of government and industry suppression of health and safety data on genetically engineered milk--the template for all of the emerging irreversible genetically engineered (GE) materials on our grocery store shelves today.

This cautionary tale empowers citizens with the facts they need to confront our industries and government when it comes to our health and the environment.

-Jane Akre

Journalist and Whistleblower fired by Fox News over the rBGH story

Dr. Epstein is a world-class optimist.  His optimism is that information on the dangers of rBGH milk will protect the public, especially in children, from these risks.   Dr. Epstein's groundbreaking new book, What's In Your Milk?, is likely to prevent these risks.

-Peter I. Hardin

Editor/Publisher, The Milkweed (influential monthly publication covering the U.S. dairy industry)

This gripping book is a classic case history of how systemic corporate crime undermines public health and democracy.  It is also an aspiring tale of how countervailing heroes can stop a corporate giant and show how great a difference one person can make.

Dr. Sam Epstein deserves high praise for his courageous and impeccable piece of science and scholarship.

-Kenny Ausubel

Author, Seeds of Change

Director, Bioneers

Dr. Samuel Epstein is a rare scientist these days who has the courage to speak up against powerful corporate interests overwhelmingly focused on their bottom line, with indifference to food safety.  His battle against Monsanto's dangerous rBGH milk, detailed here, is a cautionary tale for our health writ large in a country increasingly beholden to corporate interests above public health.

-Anna Lappe

Co-author, Grub:  Ideas for an Urban, Organic Kitchen

Dr. Epstein, true to form, as he has done this many times in the past, reveals a frightening account of a botched human experiment carried out on a huge scale by Monsanto, a profit- and power-hungry, deceitful and greedy biotech company, by forcing genetically engineered (rBGH) milk down the throat of the American public with the connivance of politicians and regulatory agencies.  As the scientifically demonstrated health risks of rBGH milk are born mainly children and juveniles, this is the more detestable.  I am glad that, despite huge political pressure from the U.S. and World Trade Organization sanctions, at least in this case, the European Union has put the health and well-being of its citizens before corporate profit, and banned the use of rBGH.

-Arpad Pusztai, Ph.D.

Leading international scientific expert on genetically modified foods



As Arthur Schopenhaur said, "There are three steps in the revelation of any truth:  in the first, it is ridiculed; in the second, resisted; in the third, it is considered self-evident."   I feel confident that Dr. Epstein's outstanding new book will finally lead us to the realization of that truth.   The book is a must for every concerned U.S. family.

-Ben Cohen, Co-Founder Ben & Jerry's Ice Cream

President, Business Leaders for Sensible Priorities


" . . . as the book shows, corporate power and spin are enormous.  It takes more than just the science to fight it.  And that is Dr. Epstein is the hero of this drama.  He is more than just a scientist.  He is a public health activist looking out for us all.   Thank you Sam."
