First you need to know, bacteria adhere to a greater extent to cut than to uncut fresh greens, thus a need for a disinfectant.

2. The most common washing fluid used by packaging companies is water, with a small amount of chlorine mixed in. This is the same chemical used in Swimming Pools and it helps kill off bacteria. Even organic salad mixes use chlorine. Although chlorine is a toxic gas, when dissolved in water in small amounts there is virtually no risk to human health.

3. A few years ago, some companies started testing new disinfectants using organic acids, for example lactic acid (found in milk) and peracetic acid. Fresh Express (owned by Chiquita) is using this mix, called FreshRinse, in its products.
