Frequently Asked Questions

What's the difference between expiration and best quality dates?

While unopened ketchup can last indefinitely if stored properly, its quality may begin to degrade after the 'best by' date. Over time, the color may darken, and the flavor can lose its sharpness. However, ketchup is safe to consume past the expiration date as long as there are no signs of spoilage like off odors or mold. The taste may not be as optimal, but it should still be safe to use.

How can I tell if Ketchup Catsup Commercially Bottled Unopened has gone bad?

To check if commercially bottled unopened ketchup has gone bad, look for any signs of mold, discoloration, or separation. Smell for any unusual or off-putting odors and check for any changes in texture, such as clumping or thinning. If you notice any of these indicators, it's best to discard the ketchup to avoid any potential health risks.

What are the food safety risks?

Ketchup may pose a minimal risk of foodborne illness due to its high acidity and preservatives. However, contamination can occur from improper handling or storage.

What are some pro storage tips?

To maintain the best quality of ketchup, store it in a cool, dry place away from direct sunlight. Once opened, refrigerate the bottle to prolong its shelf life and preserve flavor.
