I just read three pieces that show the power of transparency in the food system.

First was the op-ed in the Times I missed yesterday on the conditions of sows in the pork industry (should we call it the pig industry?). Nicolette Hahn Niman points out that Smithfield Farm recently decided to stop using gestation cages which "virtually immobilize pigs during their pregnancies in metal stalls so narrow they are unable to turn around."

Getting rid of gestation crates (already on their way out in the European Union) is welcome and long overdue, but more action is needed to end inhumane conditions at America’s hog farms.

Of the 60 million pigs in the United States, over 95 percent are continuously confined in metal buildings, including the almost five million sows in crates. In such setups, feed is automatically delivered to animals who are forced to urinate and defecate where they eat and sleep. Their waste festers in large pits a few feet below their hooves. Intense ammonia and hydrogen sulfide fumes from these pits fill pigs’ lungs and sensitive nostrils. No straw is provided to the animals because that would gum up the works (as it would if you tossed straw into your toilet).

You get the picture. I saw another email on how this sort of knowledge is affecting producers - in this case, in the dairy industry. The source was Dairy Line, a trade publisher for milk producers.

They are concerned that "well-funded activists" are raising questions about rBST, the synthetic growth hormone that pumps up milk production (and reduces the productive lifespan of cows). They blame the activists, but the fact is, consumers are voting for rBST-free milk with their wallets the more they hear about the issue.

As organic milk - which cannot be produced with synthetic hormones and antibiotics - has raised awareness on this issue, other non-organic milk companies have followed suit and are banning rBST (which is not approved for use in Europe).

The email goes onto state that "similar scenarios have developed in other arenas in recent months ... issues that affect poultry and pork production and 'We’re concerned dairy is coming under the same kind of attack,'" the email said.

As consumers learn more, production methods come under greater scrutiny and traditional agriculture feels the heat. It's happening across the food system.

Finally, transparency can effect decisions at the farm. Albert Straus, of California's Straus Family Creamery (an organic milk producer) decided to test his feed for GM contamination. According to Time magazine, he "was alarmed to find that nearly 6% of the organic corn feed he received from suppliers was "contaminated" by genetically modified (GM) organisms.

So Straus and five other natural food producers, including industry leader Whole Foods, announced last week that they would seek a new certification for their products, "non-GMO verified," in the hopes that it will become a voluntary industry standard for GM-free goods. A non-profit group called the Non-GMO Project runs the program, and the testing is conducted by an outside lab called Genetic ID. In a few weeks, Straus expects to become the first food manufacturer in the country to carry the label in addition to his "organic" one.

The bottom line: Transparency changes food production decisions. It is now having a measurable impact on what we eat.
