Formula smells like parmesan cheese?

Br

Hi guys I recently opened a tub of the Similac pro-total comfort

Anyways the tub, didn't seem tapered with, but it smells like parmesan cheese, I usually use Enfamil but since there's been like news articles with tampering, and how a baby got sick, I decided to switch formulas, my doctor recommended Similac, so im not sure if it's supposed to smell like that. Help!
