Fish and meat have a high nutritional value and are considered
easily perishable foods, as they can be contaminated from
the environment and/or during its processing. In the case of fish,
the high post mortem pH attained in the flesh, the high water
activity and the presence of free amino acids and nucleotides
make this food a readily available bacterial growth substrate
(Gram & Huss, 1996; Luten, B€orresen, & Oehlenschl€ager, 1997).
The same happens in meat, in which the high water activity,
moderate pH and readily available sources of energy, carbon and
nutrients, make this product ideal for microbial growth (Varnam
