Fermented sausages are the result of biochemical, microbiological,
physical and sensorial changes occurring in a meat mixture
during ripening in defined conditions of temperature and RH
(Villani et al., 2007). They generally did not present a sanitary risk,
but contamination of raw meat and the ability of some pathogenic
microorganisms to adapt to their environment may result in production
of unsafe sausages. Particularly, contamination of Listeria
monocytogenes occur in fermented sausages where the presence of
numerous hurdles (including salt, chemical preservatives, low
water activity and low pH, natural and/or starter microflora) may
