Foods such as salted pork, strawberry preserves, and sweet pickles do not spoil when exposed to bacteria because of their cells and its sugar and salt content. When cells have enough salt or sugar, the cell membrane (which is selectively permeable) does not allow salt or sugar into the cell and therefore does not allow bacteria into the cell. Hence, the food does not spoil.
