Can you refreeze chicken thats been thawed in water?

It isn't generally safe to refreeze raw food. This is especially true for chicken, which is contaminated with salmonella at scary-high rates. If the chicken has thawed, it isn't generally safe to refreeze it and eat it later. This is especially true if it is thawed in room-temperature water rather than being thawed in the refrigerator.

Once thawed, the chicken should be cooked fairly quickly. Once cooked, it can then be frozen for later consumption.
