Frequently Asked Questions (FAQs)
Does this calculator guarantee food safety?
No. It is a general reference only. Real food safety depends on packaging, storage conditions, temperature, and visible quality.
What does Not Recommended mean?
It means the selected storage method is not considered appropriate for that food item in this guidance model.
Can I use this for cooked leftovers?
Yes. The cooked-food section includes common leftovers and prepared foods with simple fridge/freezer guidance.
Why do some foods last longer in the freezer?
Freezing can significantly slow spoilage, so many foods have a much longer storage window there than in the fridge.
Does the calculator store my food information?
No. Calculations happen in your browser and the data is not stored.
