Final answer:
It is not safe to store food in a container that previously held a toxic material as it can transfer contaminants to the food, posing health risks. It is important to use food-grade containers designed for storing food to ensure safety.
Step-by-step explanation:
It is not safe to store food in a container that previously held a toxic material. Toxic materials can contaminate the container and transfer to the food, posing a health risk to anyone who consumes it. This can lead to foodborne illnesses and other health problems.
Even if the previous toxic material has been washed off, there is still a possibility of residue or particles remaining on the surface of the container, which can contaminate the food.
It is important to always use food-grade containers that are specifically designed to store food to ensure safety and prevent any potential health risks.
