Why Buy Organic?
Cows that produce organic milk are not treated with antibiotics or hormones; this is especially important, as drug-resistant bacteria and early-onset puberty in girls continue to be on the rise.
Price: $6.39 per gal.
Why Buy Conventional?
Cost. There's real sticker shock in paying a $3.50 premium per gallon, especially if you have milk-gulping kids in the house.
Price: $2.89 per gal.
Verdict: Go organic if you can; the extra chemistry in commercial cows is just too much.
