The importance of expiry dates varies depending on the type of product. Here’s a breakdown of different product categories and how critical their expiry dates are:

Food Products

Perishable Items (e.g., dairy, meat, fresh produce): Expiry dates are crucial for safety. Consuming these items past their expiration date can lead to foodborne illnesses due to bacterial growth.
Non-Perishable Items (e.g., canned goods, dry pasta): These items often have a “best by” date rather than a strict expiration date. They can usually be consumed past this date, but the quality, taste, and nutritional value may decline.

Pharmaceuticals

Medicines: Expiry dates are essential, as drugs’ chemical composition can change over time, potentially making them less effective or harmful. Always check and adhere to the expiration dates of medications.
OTC (over-the-counter) drugs: While some might remain effective past their expiration date, it’s not guaranteed. Potency and safety can diminish.

Cosmetics and Personal Care Products

Cosmetics (e.g., makeup, lotions): Expiry dates help ensure product effectiveness and prevent skin irritation or infections. Opened products have a shorter shelf life due to contamination from exposure.
Personal Care Items (e.g., shampoo, toothpaste): These products might lose effectiveness over time but are generally not harmful if used slightly past their expiry date.

Household Products

Cleaning Supplies: Expiry dates on these products often refer to effectiveness rather than safety. Using them past the expiry date might result in reduced cleaning power.
Batteries: Over time, batteries can lose their charge capacity. While not harmful, they may not perform as expected.

Summary

Safety: Critical for perishable foods and pharmaceuticals.
Effectiveness: It is important for all categories to ensure optimal performance.
Quality: Relevant for non-perishable foods, cosmetics, and personal care items.

It is best to adhere to expiration dates when in doubt, especially for items that impact health and safety. For non-critical items, using them shortly past the expiration date is usually acceptable, but always be cautious of changes in appearance, smell, or performance.
