Compost Manure to Avoid E. Coli and Other Foodborne Pathogens

A deadly E. coli outbreak in northern Germany had government officials originally suspecting sprouts from an organic farm to be the cause. However, in a statement released Monday, June 6, test results were released that found no evidence that sprouts from an organic farm were the cause of the outbreak, according to The Associated Press.

As of Thursday, June 16, over 3,000 German citizens, mostly adults, had been effected by the rare E. coli O104:H4 strain, according to Food Saftey News’ website.

The geographic source of the outbreak is still unknown; however, the E. coli epidemic has been linked specifically to bean sprouts and no other vegetable. The sprouts are responsible for the worst recorded outbreak of E. coli infections and a death toll of 39 people.

Mark A. Kastel, co-director and senior farm policy analyst at The Cornucopia Institute, a farm policy research group based in Cornucopia, Wis.,reminds us how important it is to know the origin of your manure, otherwise it could become the source of spreading foodborne pathogens such as E. coli.

The new practice of raising beef and dairy cattle on highly concentrated factory farms and feeding them grain in high rations changes the pH in cattle rumen, according to Kastel. These pH changes are responsible for creating more deadly E. coli pathogens, which are alive and well in manure.

When we spread this type of manure around growing produce, eating that produce raw becomes dangerous. Using contaminated manure from concentrated factory farms can encourage the spread of highly toxic strains of foodborne pathogens in raw food.

To kill these pathogens, organic farmers are required to compost their manure before they spread it on crops. Conventional farms, however, are not required to follow this strict management practice. As a result, the U.S. Food and Drug Administration has seen 10 sprout recalls in the past two and a half years (since April 2009). Nine of these were because sprouts from conventional farms tested positive for foodborne pathogens, while only one was because sprouts from an organic farm tested positive (90 percent conventional, 10 percent organic).
