How should stored food be contained to ensure safety?

Stored food should be contained in vermin-proof containers to ensure safety. This is crucial because these containers prevent pests, such as rodents and insects, from accessing the food. Vermin-proof containers are typically made of durable materials that seal tightly, thus reducing the risk of contamination and preserving the food's integrity. Ensuring that food storage is pest-proof is critical for maintaining hygiene standards and preventing foodborne illnesses.

In contrast, plastic containers, while useful for many purposes, may not be entirely effective in keeping vermin out unless they have tight-fitting lids. Open containers provide no protection against pests at all, making them highly unsuitable for storing food. Cardboard boxes may offer some level of protection but are not ideal for long-term food storage since they can be easily penetrated by pests and are also susceptible to moisture damage. This highlights the importance of using specifically designed vermin-proof containers for safe food storage practices.
