It's not about safety, it's about mouthfeel and flavor. Freezing and
thawing almost all meats and veggies will result in cell wall
destruction. The protoplasm leaks out of the damaged ones. Refreezing
damages still more cells and reduces still more the juices and,
therefore, flavors. Texture is damaged because empty cells are tough
and tasteless.
