Prepackaged Salad Mixes: Are They Really Safe?

Packaging concerns

One area where bagged salads may fall short is in the packaging. Though the airtight nature of plastic bags can slow the process of food spoilage, it also allows the produce to be crushed during transport and storage. Some studies indicate that the liquid that seeps from crushed leaves is more likely to support the growth of salmonella.

Still, let your eyes be your guide in your purchasing decisions. You can tell by looking if the leaves inside the bag are fresh and crisp or if they have become wilted and bruised.

Another option in packaged greens is clamshell packaging, or plastic boxes, rather than bags. This provides a bit more protection for the produce during shipping and storage.
