Does honey ever go bad?
Archaeologists found 3,000-year-old honey in ancient Egyptian tombs that is still perfectly safe to eat today.
Honey is a super-food that never goes bad because it has very little water and is naturally acidic. Bacteria cannot grow in it because the honey actually sucks the moisture out of them. Bees also add a special enzyme that creates hydrogen peroxide, which keeps the honey fresh for thousands of years.

When Howard Carter opened King Tutankhamun's tomb in 1922, he found jars of honey from 1323 BCE that were still liquid. This happens because honey is only about 17% water. This low moisture creates something called osmotic pressure. It works like a vacuum that pulls water out of any bacteria that try to grow there, drying them out until they die.Honey is also very acidic, with a pH level around 3.9. Most germs like Salmonella need a neutral environment to live, so they cannot survive in the honey's acid. While making honey, bees mix nectar with an enzyme called glucose oxidase. This enzyme creates gluconic acid and hydrogen peroxide. The hydrogen peroxide acts as a shield that stops fungi and bacteria from moving in.The ancient Egyptians were also smart about how they stored it. They put the honey in clay jars and sealed them with wax to keep air out. Since honey is hygroscopic, it normally drinks up moisture from the air. If the jars weren't sealed, the honey would have soaked up water and spoiled. Scientists at the Texas A&M University Honey Bee Lab say that if the seal stays tight, honey is one of the only foods that can last forever.
