Which of the following can lead to increased cost due to waste?

Choosing poor food management practices can lead to increased costs due to waste. This is because ineffective management can result in improper food handling, storage, and inventory control, which can lead to spoilage, contamination, and overall loss of food products. When perishable items are not stored correctly, or if there's a failure to track inventory, it can cause foods to go unused until they are no longer safe or suitable for consumption. Additionally, mismanagement can lead to over-preparation, where food that is made isn't sold or consumed in a timely manner, further contributing to waste and financial loss.

In contrast, proper food storage, buying in large quantities wisely, and maintaining food safety standards are practices that generally help reduce waste and control costs. Proper food storage preserves the quality and longevity of food items. Purchasing in bulk can be cost-effective if managed well, as it usually reduces overall expense while minimizing the potential for waste. Maintaining food safety standards also ensures that food is handled properly, extending its shelf life and reducing the risk of spoilage.
