Article Abstract
The study aimed to evaluate the synergistic interaction of organic acids (OAAs) or lemon extract (LE) plus mild heat (MH; 55 °C) against O157:H7, serovar Typhimurium, and inoculated in beetroot and watermelon juices. A mixed culture cocktail of . O157:H7, . Typhimurium or . was inoculated in beetroot or watermelon juice, followed by treatments with MH, citric acid MH, malic acid MH, tartaric acid MH, and LE MH. Approximately 2.0-log reductions in the number of . O157:H7, . Typhimurium, and . were observed when these bacteria were heated in juices at 55 °C for 5 min. A combination of 1.0% OAAs or 20% LE and MH (55 °C) for 5 min resulted in an additional log-reduction in the count of . O157:H7, . Typhimurium, and . by 2.2-5.0, 4.5-5.0, and 1.5-5.0, respectively.

is a leading cause of foodborne illness in the United States and worldwide. This enteric pathogen deploys various mechanisms to evade the intestinal mucosal barrier to enhance its survival and further infect systemic tissues. Commercially available vaccines against are currently restricted to the serovar Typhi, while none are currently approved for non-typhoidal (NTS) serovars, which are becoming increasingly resistant to antibiotics.

Recent foodborne illness outbreaks linked to lettuce and cucumbers have prompted research into the sources of contamination and the risks of pathogen internalization within the edible portions. This study assessed the colonization and presence of Escherichia coli O157:H7 and Salmonella enterica ser. Typhimurium in romaine lettuce (True Heart, Rio Bravo) and cucumber (Mini-Me, Gherkin) varieties under greenhouse conditions.

Hydroponic nutrient solution (HNS) has been established as an ideal conduit for pathogen contamination and proliferation. This study evaluated the efficacy of lactic acid bacteria and their metabolites in mitigating the risk of foodborne pathogens in HNS when compared to conventional chemical treatments. Hoagland's HNS were prepared according to the manufacturer's instructions and inoculated with Typhimurium, 0157:H7, and at 10 CFU/mL cell concentration.
