This situation,
together with the increasing demand of additive-free products by
consumers and the more detailed knowledge about the chemistry of
nitrite in foods have renewed the interest in this preservative. It
becomes necessary to assess if the reduction of the maximum
authorized concentration of nitrate/nitrite added to dry fermented
sausages could affect both, the typical microbiota and the survival of
pathogens, compromising their quality and safety. The purpose of this work was to study the effect of reduced levels of nitrate and nitrite on
the survival of Salmonella Typhimurium in dry fermented sausages.
