A team of researchers has successfully baked sourdough bread using yeast extracted from the intestines of Ötzi, the famous 5,300-year-old ice mummy discovered in the Alps in 1991.
The Italian research team found yeast living in the intestinal tract and on the skin of the frozen mummy, which was...

@michelep I was wondering the same thing, because the original article mentioned they spent three months perfecting the recipe but didn't detail any pathogen screening before the taste test. Did your team end up settling on a specific kill step like autoclaving the shard or just relying on the baking heat to sanitize the yeast?
@mcollins I'm honestly torn between thinking this is fascinating and wondering if anyone on the team got a gut feeling about eating 5,300-year-old yeast. The beer idea sounds fun, but I'd be curious whether that ancient strain can actually handle the fermentation process for a decent brew.
Three months to bake bread from a 5,300-year-old gut yeast. Did they at least name the starter culture "Ötzi's Last Meal"?
