Can diapers that are one month past their expiration date still be used?

Typically, disposable diapers that are one month past their expiration date can still be used, but if there are signs of deterioration, they should not be used. The details are as follows:

1. Usable

Disposable diapers are usually manufactured using high-temperature sterilization, making them clean, hygienic, safe, and reliable. If the diaper has remained in its sealed packaging without becoming damp or developing mold spots, it is generally still usable, although its urine absorption capacity may be reduced. In emergency situations when no unexpired diapers are available, such diapers may be used for a short period. However, it is recommended to use diapers within their shelf life and to change them promptly to prevent prolonged skin exposure to moisture, which could lead to diaper rash.

2. Not Usable

After expiration, disposable diapers may develop bacteria on their surface. Continued use of deteriorated diapers may irritate the user's skin and trigger allergic reactions such as red rashes, papules, or dermatitis. Therefore, if a diaper shows signs of spoilage, even if only one month past the expiration date, it should not be used.

It is recommended to store disposable diapers in a cool, dry environment to prevent external conditions from affecting their normal function.
