Survival of foot-and-mouth disease virus in sausage meat products (Italian salami)

Determination of the survival of foot- and-mouth disease virus (FMDV) in fresh meat from experimentally infected swine and in several types of sausage meat (Italian salami) produced according to the technology widely applied by the principal Italian producers has been carried out. The purpose of the experiment was to assess if typical Italian salami can be considered safe with regard to the spread of FMD through international trade. The results obtained showed: (a) high titers of FMDV were detected in both muscle and fat tissues from animals slaughtered at the peak of the experimental disease; and (b) FMDV was not detectable in the above tissues 72 h after slaughtering and the same applies to the different types of salami tested 7 days after production. The above results were obtained in tissue cultures and confirmed through piglet inoculation.
