I can share that in general, slow cookers are considered safe and easy to use appliances when used correctly. The most common issues that may arise with slow cookers are related to overcooking or undercooking food, which can be easily avoided by following recipes and recommended cooking times.
It's important to remember always to read the manufacturer's instructions, use the slow cooker on a flat, stable surface, and ensure that it's in good working condition. Additionally, practicing proper food safety measures, such as thawing meat before cooking and avoiding leaving perishable foods out at room temperature for extended periods, can help prevent any potential issues while using a slow cooker.
