Answer:
Some bacteria are used as indicators because if they are present in the product, we can say that it is a product with the presence of pathogens that will cause diseases. Some of them are: total coliforms, fecal coliforms and enterococci.
To be a good indicator they must have a correlation with the pathogens and be more abundant than them. Its presence in a food indicates the possible presence simultaneous pathogen microorganisms. For example, E. coli has been used as Index of possible presence of pathogens of enteric origin in water and food
