Last updated: September 2026. Please read this page carefully before using our calculators.

Educational information only

All content on ProduceGuide — calculators, articles, tables, and examples — is published for general educational purposes. It is not professional advice and is not a substitute for a qualified professional. We are not qualified professional in the relevant fields, and no client or advisory relationship is created by your use of this Site.

Entries summarize standard food-storage guidance from USDA and extension research. Shelf lives are typical ranges — when in doubt, look and smell before eating.

When produce shows mold, off smells, or sliminess beyond surface wilting, discard it. "Wilting is reversible; rot is not."

Accuracy of calculations

We implement well-known, publicly documented formulas (see the methodology section on each calculator page and USDA and university extension food storage guidance as applicable). Even correctly implemented formulas produce estimates that depend on your inputs and assumptions. Real-world outcomes vary. Do not rely on a single web tool for a consequential decision.

Advertising disclosure

ProduceGuide is funded by display advertising served through Google AdSense. Advertisers have no influence over our content, formulas, or editorial choices, and placement of an ad is not an endorsement.
