Action Alert

Fair trade or free trade? Let your voice be heard on Minnesota’s future!

The Obama Administration is negotiating two new mega trade deals (one with Pacific Rim countries, another with Europe) entirely in secret, with the goal of further expanding the NAFTA-model of free trade. These trade agreements could have major impacts on Minnesota's farmers, workers, small business owners and rural communities. They could limit Minnesota’s ability to support local food and energy systems and grow local businesses. In order to stay up to speed, Minnesota has set up a new Trade Policy Advisory Council (TPAC) to advise the state legislature and Governor.

TPAC wants to hear from Minnesotans: What concerns do you have about free trade? What role could TPAC play in the future? Now is your opportunity to have a say in our future trade policy. Complete the survey and let them know future trade negotiations should be public, not secret. Help ensure the voices of all Minnesotans are heard in the development of trade agreements and that they protect local control and our quality of life. The free trade model has failed for Minnesota and we need a new approach to trade. Help ensure the voices of all Minnesotans are heard before trade agreements are completed, and that they protect local control, our natural resources and our quality of life.

Please take five minutes and complete the survey. To find out more about these trade agreements, go to

Ethanol, antibiotics and what we don’t know

A by-product of ethanol production is something called distillers’ grains, a corn mash that’s typically dried and sold to livestock producers.

Alarming research coming out of the University of Minnesota raises concerns over the public health impacts of antibiotic use in ethanol production. 

Ethanol producers frequently add antibiotics like penicillin and erythromycin to fermentation tanks to control bacteria (bacteria compete with yeast for sugar, and too much bacteria can decrease ethanol yields). These antibiotics end up in animal feed. A by-product of ethanol production is something called distillers’ grains, a corn mash that’s typically dried and sold to livestock producers. In 2009, the FDA did extensive testing and found antibiotic residues in more than half the distillers’ grain samples they tested.

The ethanol industry played down the findings by contending that the antibiotic residues were almost certainly rendered inactive during the drying and finishing process, and therefore, not a concern (the FDA did not test for antimicrobial activity).

Now, however, new research calls that contention into question. A recent article in National Hog Farmer, a trade publication, reported on research by graduate student Devan Paulus and Professor Jerry Shurson at the University of Minnesota. Paulus and Shurson tested distillers’ grain samples from plants throughout the U.S. and found active antibiotic residues. The data, which has not yet been published but were confirmed in a call I made to Paulus, indicated antibiotic residues in all 117 samples tested, and antibiotic residue active enough to inhibit E. coli growth in one of the samples.

National Hog Farmer paints the study results as reassuring, but low-level antibiotic activity is a pathway to antibiotic resistance, as the antibiotics kill off susceptible bacteria leaving the “superbugs” to thrive. Even one sample in 117 testing positive for antibiotic residue is an indication that we don’t know the fate of these antibiotics or if they’re contributing to the antibiotic resistance epidemic.

Perhaps the most frustrating aspect of this issue is that these antibiotics are not necessary. Effective non-antibiotic antimicrobials are readily available to producers and used successfully by many producers, including POET, the largest producer in the country. According to POET, the switch to antibiotic-free distillers’ grains offered a market advantage: antibiotic residues are not permitted in layer hen feed.

This new data is another clear sign that ethanol producers need to move away from antibiotic use. In the meantime, we need to know more about the fate and impact of antibiotics in distillers’ grains. The FDA should do comprehensive testing of distillers’ grains for antibiotic activity and make public their results. There’s too much uncertainty, and too much at risk, to ignore this emerging problem.
