Final answer:
The food worker should change her gloves before touching ready-to-eat food after touching the buttered baking tin to avoid cross contamination and maintain food safety.
Explanation:
After using her gloved hand to rub butter in a baking tin, the food worker must change her gloves before touching any ready-to-eat food. This is to prevent cross-contamination, which happens when bacteria or other harmful substances are transferred from one surface, such as the buttered baking tin, to another, like the ready-to-eat food. Whenever a food worker transitions from handling raw or non-ready-to-eat food to ready-to-eat foods, it is crucial for them to change their gloves to maintain food safety.
