Product listings show standard pasteurization, ultra‑pasteurization (ultra‑pasteurized), UHT shelf‑stable treatment, and ultrafiltration used for higher‑protein variants.
Some whole milks are sold refrigerated and labeled “keep refrigerated,” while others are UHT shelf‑stable boxed milk that do not require refrigeration until opened.
On‑the‑go whole milk is offered in shelf‑stable single‑serve boxes (for example, 6×8 fl oz packs) that are UHT pasteurized so they can be stored without refrigeration until opened.
Labels commonly display organic certification, pasture‑raised or grass‑fed claims, non‑GMO feed, and notes such as no added antibiotics and no rBST/growth hormones.
