Weekend reading: Barry Estabrook’s Pig Tales

Barry Estabrook.  Pig Tales: An Omnivore’s Quest for Sustainable Meat.  WW Norton, 2015.

I was happy to be asked to blurb this one.  It’s a great read:

Estabrook tells two powerful stories here.  The first is about the appalling ways in which Big Pig raises animals, pollutes the environment, and uses the political system to avoid and fight regulation.  The second is about how skilled animal husbandry and respect for the intelligence of pigs produces calmer animals, more delicious meat, and a far more satisfying life for farmers and pigs alike.  Pig Tales is beautifully written.  It is also deeply touching.

Is free-range pork more contaminated than industrial pork?

My e-mail inbox is flooded with copies of an op-ed from today’s New York Times arguing that pigs running around outside have “higher rates” of Salmonella, toxoplasma, and, most alarming, trichina than pigs raised in factory farms. The writer,  James McWilliams, is a prize-winning historian at Texas State San Marcos whose forthcoming book is about the dangers of the locavore movement to the future of food.

I put “higher rates” in quotation marks because that is not what the study measured.  The study on which McWilliams based his op-ed is published in Foodborne Pathogens and Disease. The investigators actually measured “seropositivity” (antibodies) in the pigs’ blood.  But the presence of antibodies does not necessarily mean that the animals – or their meat – are infected.  It means that the free-range pigs were exposed to the organisms at some point and developed immunity to them.  The industrial pigs were not exposed and did not develop immunity to these microorganisms.  But you would never know that from reading the op-ed.   How come?

Guess who paid for the study?  The National Pork Board, of course.

The Center for a Livable Future at Johns Hopkins has much to say about all this.  My point, as always, is that sponsored studies are invariably designed in ways that produce results favorable to the sponsor.    In this case, the sponsor represents industrial pork producers.

April 14 update:  the editors of the New York Times have added a note to the electronic version of Professor McWilliams’ op-ed pointing out the National Pork Board sponsorship of the study on which he based his piece.  And McWilliams rebuts arguments against his piece on the Atlantic Food Channel, while conceding that he may have gotten the science wrong.
