what are Specific spoilage organisms
The main culprits are microbial organisms known as specific spoilage organisms (SSOs). The concept of SSOs arises from the fact that not all bacteria cause food spoilage; indeed, the degree of food spoilage is not proportional to the amount of microbes present on the food.n general, without further preservation techniques, the environment of a fresh fish provides an abundance of biosynthetic materials that the spoilage organisms such as Shewanella putrefaciens and Pseudomonas spp. can readily use to survive and proliferate.
