“Lettuce is so thin and fragile,” defined Trevor Craig, a meals security professional and company director of technical coaching and consulting at Microbac Laboratories. “It breaks down easily and produces a lot of liquid.”

“The primary reasons behind this discoloration are due to improper handling and storage,” she stated. “If the leaves are bruised or cut, or if the lettuce is stored with an excess of moisture, this can result in much faster development of rust on your leaves.”
Over time, as lettuce oxidizes, it produces polyphenols ― plant compounds with quite a few well being advantages ― as a protecting measure to forestall the expansion of mould and fungi. This may give it the rust look, Sabatini stated. Another contributor is publicity to ethylene fuel that’s naturally emitted by different produce in your fridge.
The rusty discoloration could also be ugly, nevertheless it doesn’t make the lettuce unsafe to eat, Sabatini stated. You can simply chop it off if it bothers you.
“As long as your lettuce is still crisp and the rest of the leaves appear vibrant and firm, it’s safe to eat the pink parts,” she defined.
Why do some packaged greens get moist and soggy?
The fragile nature of leafy greens makes them delicate to being jostled or crushed throughout selecting, packaging or transport, Craig stated. As a end result, the greens would possibly look wilted, darkish inexperienced or soggy, however they’re not essentially unsafe.
However, darkish or moist leaves can sign spoilage, Sabatini stated. As greens age, they launch moisture, which causes them to darken or get soggy. Overpacking, temperature adjustments throughout transport, and improper storage may improve moisture.
Harmful micro organism, like E. coli, salmonella or listeria, can begin to develop in all this further moisture, which can improve the chance of constructing you sick, Craig stated.

Best-by dates can inform you how lengthy the greens ought to keep recent, not essentially how lengthy they’re fit for human consumption. Sell-by dates inform retailers how lengthy to show a product, however you need to use it as a information to purchase the freshest pack on the shelf.
Usually, if the greens nonetheless look good previous the dates on the bundle, they’re doubtless fit for human consumption, Craig stated.
How to securely retailer and eat greens at dwelling.
Storing salad greens appropriately will assist maintain them recent for longer. Sabatini recommended preserving leafy greens separate from different vegatables and fruits to reduce ethylene fuel publicity.
