一般说多数细菌“怕”盐,在盐渍的食品中很难生存。但也有不怕盐的细菌,如“副溶血性弧菌”就恰恰喜欢含盐的环境。因此,有人把这类细菌统称为“嗜盐性弧菌群”(简称“嗜盐菌”)。嗜盐菌广泛存在于含有一定盐分的海水、海底部沉积物及海产食品中(如海鱼、海虾、海蟹及贝类),在冷荤食品如自鸡、猪头肉等肉菜中也极易生长繁殖。

In general, most bacteria are “scared” of salt and hardly survive in salted foods. But there are also bacteria that are not afraid of salt, such as “Vibrio parahaemolyticus” just like the salty environment. Therefore, some people refer to these bacteria as “halophilic Vibrio species” (“Halobacterium”). Halophilic bacteria exist widely in seawater, sea bottom sediments and marine products (such as sea fish, shrimp, sea crabs and shellfish) containing a certain amount of salt. They are also very easy to eat in cold meat dishes such as chicken and pig meat Growth and reproduction.
