Histamine Tracker
Swiss cheese
Swiss cheese develops significant histamine during its months-long aging process through bacterial activity.
Classic Swiss cheese is aged for several months, and bacterial activity during that time is associated with histamine and other biogenic amine accumulation.
-
Aging bacteria — while the propionic acid bacteria that create Swiss cheese's signature flavor and holes are not well-established as significant histamine producers, other bacterial species active during aging are associated with histamine accumulation in this style of cheese
-
Younger Swiss vs. aged — mild, lightly aged Swiss will typically carry less histamine than older, sharper varieties, so the flavor intensity of a given block can serve as a rough guide
Opting for the mildest, freshest-tasting Swiss available may offer a more manageable starting point.
