Hello, I'm an expert in the field of confectionery and food science. Let's address your question about the shelf life of lollipops.

Lollipops, like many sugar-based confections, do not typically "go off" in the sense that they spoil or become inedible due to bacterial growth. However, they can change in quality over time. The sugar in lollipops acts as a preservative, which helps to inhibit the growth of bacteria and mold.

Factors that can affect the shelf life of lollipops include:

1. Storage conditions: If lollipops are exposed to heat and humidity, they can melt or become sticky.

2. Ingredients: Some lollipops may contain perishable ingredients like fruit purees that can affect their shelf life.

3. Packaging: Proper packaging can help protect lollipops from contaminants and extend their shelf life.

While they may not spoil, lollipops can become stale, which means they lose their original freshness and become hard or less flavorful. This is more a matter of quality degradation rather than safety.

In general, if stored in a cool, dry place and protected from light, lollipops can last for a long time, sometimes up to a year or more. However, it's always best to check the packaging for a best by or use by date recommended by the manufacturer.
