The trial was conducted on smoked salmon samples experimentally contaminated with a cocktail of 4 strains of <em>Listeria monocytogenes</em> (LM ATCC 19114, LM ATCC 15313, LM ATCC 19111 and LM ATCC 7644) at a final concentration of 8 log cfu/g and kept at 4°C until its use. Thermosonication treatments between 40°C and 50°C for 5, 10 and 15 minutes proved to be more effective without altering the sensory characteristics of the food.</p> ER -
