Sausages containing bacteria from baby feces could be good for digestion, Spanish scientists say.
With more and more evidence showing the importance of gut health, bacteria from baby poop could make savory meats probiotic.
An imbalance between healthy and unhealthy gut bacteria is associated with cancer, diabetes and inflammatory bowel disease. Probiotics are thought to help balance bacteria, but their effects have not been proven.
Sausages are usually fermented by bacteria naturally found in raw meat or by commercial bacteria added to the meat. The bacteria creates lactic acid that dries out the meat and keeps germs from spreading and spoiling the sausage. Unfortunately, it’s difficult for these healthy bacteria to survive the acid in our stomachs. That’s why researchers turned to baby poo.

Infant feces contain far more probiotics, like Lactobacillus and Bifidobacterium, than adult excrement.
Researchers used fecal samples from diapers of healthy infants up to 6 months old. Bacteria was cultured from the samples and added to fermented sausages. Scientists stressed that feces weren’t present in the food.
Tasters and scientists said the sausages tasted perfectly normal.
"Probiotic fermented sausages will give an opportunity to consumers who don't take dairy products the possibility to include probiotic foods to their diet," said study co-author Anna Jofré, a food microbiologist at Catalonia's Institute of Food and Agricultural Research's food-safety program.
