Milk safety is a top priority, and we thoroughly clean our equipment between milking and bottling sessions. This keeps bacteria counts low and makes our raw milk last longer than most.
We use cleaning products that are "certified for organic". They contain hydrogen peroxide, acetic acid, peracetic acid, phosphoric and sulfuric acids, sodium tripolyphosphate, and organic chlorine. After using these cleaners, all milking and bottling equipment is flushed with very hot water, so, if there were any residue, it would be in trace amounts.
