As many times as you finish one task and begin another.
Under foodservice rules, no, you cannot. Gloves are meant to be single use disposable. This means you wash your hands, wear the gloves for one task, remove them and dispose of them. It is not necessary to wear gloves on break. Never wash and reuse gloves.
Disposable gloves keep you from catching disease or contaminating a sample.
If they are not single-use, disposable gloves and they hold up to being washed and sanitized, they can be reused.
Most disposable gloves are made of plastic, and are not organic. Some are made of latex rubber, which is from a plant (organic).
In 1964 they introduced the disposable latex gloves for use in surgery.
when you are cleaning

You need to change your gloves anytime you touch something that you do not want to spread to somewhere else. For example, I use chemicals at work that if mixed could be an issue, so I replace my gloves any time I change chemicals. However, I don't change them if I'm using the same chemical all day. A nurse would change his/her gloves any time he/she leave a patient. You should wash your hands every time you take off your gloves.
Rubber gloves are great for general cleaning and are disposable as well!
To prevent cross contamination
Try a good thick, laytext glove, such as disposable gloves for dishwashing found at the dishwashing section of your local grocerie store. :)
When handling raw meat, it is recommended to use disposable gloves made from nitrile or polyethylene. Nitrile gloves offer better puncture resistance and are more durable, making them suitable for food handling. Polyethylene gloves are less expensive and provide a good barrier against contaminants but are less durable than nitrile. Always ensure that the gloves are food-safe and change them frequently to prevent cross-contamination.
