I buy butter in a small tub & if I don’t leave it out, I can’t spread it. It is alway covered. Unused containers are kept sealed & refrigerated until ready to use, tho. Haven’t had any health problems with it so far & this includes several years.
I agree, the thing is Land o Lakes introduces the thought, you wouldn’t want your buttr to have you serve lower qulity foods to your friends or family would you ?
