Cheese enthusiasts take their hobby pretty seriously. That’s why when the world’s oldest cheese was found in an Egyptian tomb this week, people started proclaiming en masse that they wanted to try it, which of course led experts to come out and advise something you would never think necessary: don’t.
Researchers are warning that the 3,200-year-old cheese could be poisonous. Made either of cow or goat milk, the cheese may contain a fatal infectious disease called brucellosis. According to the CDC, it’s an infection spread by eating unpasteurized or raw dairy products and infected animals.
