Details About the oldest animal humans eat:

When produced into food, chickens are often only six weeks old. Pigs are six months of age. Cows are 18 months old. While land animals are young, marine life provides us with much older food. In culinary form, tuna has an average shelf life of five to fifteen years, although lobster is typically the oldest. Because they don’t age very much, 50–100-year-old lobsters are frequently seen in the sea. Based on size, most of the lobsters we eat are between five and eight years old, although some can be over thirty.
