Storage & Reheating Tips

- •After opening, refrigeration extends shelf life and maintains quality
- •Always use clean utensils when scooping ketchup to prevent contamination
- •Wipe the bottle rim clean after each use to prevent crust formation
- •Keep the cap tightly sealed when not in use
- •If ketchup separates (watery layer on top), shake well before using

- •Single-serve packets can be stored at room temperature until the printed date
Food Safety Reminder
