While generally safe, refreezing partially thawed fish is likely to lead to some loss of texture and flavor, and is best avoided unless absolutely necessary. The same is true of some dairy products, such as milk and cheese. Partially thawed and refrozen fruits and vegetables are also liable to diminish in quality, but are generally safer than fish, provided they do not look or smell bad and they have not been held above 40° F for longer than 6 hours.
