Popis: Salmonella enterica, known for its resilience to acidic environments, has been linked to foodborne outbreaks of illness from fruit derivatives. This study aimed to assess the survival of five serovars of Salmonella enterica subsp. enterica in various fruit purees subjected to different storage temperatures. Among the studied serovars, S. enteritidis exhibited the most significant population decrease in all fruit purees. In contrast, S. Agona, S. Gaminara, S. Michigan, and S. Montevideo survived in peach puree at 4 °C for at least 3 days, and S. Agona, S. Gaminara, and S. Montevideo maintained their initial levels in pear puree under the same time/temperature conditions. However, none of the strains were detectable in plum and black currant purees after 2 days at 4, 15, or 25 °C. These findings highlight variations in the behaviour of S. enterica serovars within different fruit purees. Likewise, low-temperature conditions prolonged the survival of the tested strains in all fruit purees analysed.
