How to Tell if Ketchup Has Gone Bad: A Comprehensive Guide

Ketchup is one of the most commonly used condiments in the world, and it’s a staple in many households. However, like any other food product, ketchup can go bad if not stored properly or if it’s past its expiration date. Consuming expired or spoiled ketchup can lead to foodborne illnesses, which is why it’s essential to know how to tell if ketchup has gone bad. In this article, we’ll discuss the signs of spoiled ketchup, how to store ketchup properly, and tips for extending its shelf life.

Understanding Ketchup’s Shelf Life

Ketchup is a condiment made from tomatoes, vinegar, sugar, and spices. Its shelf life depends on various factors, including the manufacturing process, storage conditions, and handling practices. Generally, unopened ketchup can last for up to 5-10 years if stored in a cool, dry place.
