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.

Tangent on tangent - in addition to the antifungal there is also anticaking agent (nothing crazy, often some type of flour) that noticeably changes the mouthfeel of cheeses that come pre-shredded. If you notice a grainy texture in your food, try grating it off a brick instead!

People are super religious about this but I've never been able to tell pre-shredded cheese from cheese I've shredded myself and I don't think anyone else can tell the difference in a blind taste test.

That's actually crazy to me. Like, a sealed, generic brand bag from the cold section of a chain grocery store vs a block purchased from the deli and shredded by hand? The difference is massive! Taste will vary between the two anyways but the texture difference is categorical. The pre shredded has grainy flour like stuff all over it, the manually shredded is completely smooth with no graininess at all. I can 1000% tell the difference in any kind of test you want to do.

Where are you buying cheese that this comparison isn't noticable?
