🛒 Expert tips: How to safely buy and store deli meats
To keep your ham fresh and minimize worries:
Buy from trusted sources: Choose pre-packaged meats with clear expiration dates or ask for freshly sliced meat at the deli counter.
Check the “best before” or “sell by” date: Consume pre-packaged deli meats within 7 days of opening; freshly sliced deli meats within 3 to 5 days.
Store properly: Keep in the coldest part of the refrigerator (≤40°F/4°C), ideally in an airtight container to limit oxygen exposure.
When in doubt, throw it out: Deli meats are perishable, don’t risk foodborne illness.
❤️ The end result
That mesmerizing rainbow on the ham isn’t a warning: It’s just the light dancing on the protein. As long as the meat smells fresh, feels firm, and has been stored properly, it’s perfectly safe to eat.
So go ahead, make that sandwich. Perhaps you’ll just admire the colors first. 🌈
