Why is it not recommended to use a glass to scoop ice?

Using a glass to scoop ice is discouraged primarily because it poses a risk of breaking or chipping. When a glass is used to scoop ice, it can easily slip or make contact with hard surfaces, leading to cracks or pieces breaking off. These fragments may contaminate the ice, which is meant to be a clean and safe product for consumption. Keeping ice free from potential contaminants is crucial to ensure food safety, as any introduction of foreign materials can lead to foodborne illness.

While other factors, such as transferring heat or holding bacteria, are relevant to food safety, the immediate concern is the physical integrity of the glass. This makes option A the most compelling reason against using glass in this manner. Additionally, while glass can potentially absorb odors or hold bacteria, these issues are generally less significant when compared to the risk of breaking, which can lead to immediate visual contamination of the ice.
