In a similar study conducted by Chen et al. (2007) on
crayfish tails stored at 2 8C, results showed very different
pattern when samples were stored in MAP, observing coliform
count of 5.5 log CFU/g after six days of storage. Chen et al.
(2007) also observed an increase in total coliforms from
3 log CFU/g on day 2 of storage to 6.5 log CFU/g after 14 days of
storage in vacuum-packed crayfish tails stored at 2 8C. Linton
et al. (2003) on the other hand, did not detect any coliforms on
prawns treated with hydrostatic pressure and stored at 2 8C
during a 28 days period of storage. There are many factors that
may determine the presence or absence of coliform, such as
the environment the prawns lived in such as fresh or salt
water and also how they were harvested and processed.
