It’s not mold, it’s calcium lactate (2018)

Tangential, but I recently noticed that natamycin, an antifungal agent, is being used in packages of shredded cheese as a preservative.

I was a little taken aback on seeing it, given that antibiotic stewardship has been pushed so much in the last decade.

I realize that natamycin is an antifungal and not an antibiotic, and that mechanisms of developing resistance are likely different between eukaryotes and prokaryotes. However, I’m still somewhat concerned what long-term low-level exposure will mean.

"True, fungi cannot survive if its host's internal temperature is over 94 degrees," says Neuman. "Currently, there are no reasons for fungi to evolve to withstand higher temperatures. But what if that were to change? What if, for instance, the world were to get slightly warmer? Now there is reason to evolve."

Thanks for reminding me to rewatch it before the new season comes out (soon).
