Salmonella is a foodborne pathogen of global significance and is highly prevalent in pork. This study investigated the prevalence, contamination distribution, virulence genes and antibiotic resistance of Salmonella in 3 pork processors in the Shandong Province of China. Samples were collected from 13 different sampling sources across the slaughter procedures (600 samples) as well as at retail outlets supplied by these processors (45 samples).

Lately, the inclusion of additional lactic acid bacteria (LAB) strains to cheeses is becoming more popular since they can affect cheese's nutritional, technological, and sensory properties, as well as increase the product's safety. This work studied the effect of L33 and L125 free cells and supernatants on feta cheese quality and fate. In addition, rapid and non-invasive techniques such as Fourier transform infrared (FTIR) and multispectral imaging (MSI) analysis were used to classify the cheese samples based on their sensory attributes.

Article Synopsis
  • - This study investigated the impact of FMCC-B281 cells and their supernatant on the spoilage and survival of E. coli O157:H7 in fresh-cut salads, specifically romaine lettuce, rocket cabbage, and white cabbage, during storage.
  • - The researchers used modified atmosphere packaging and monitored microbial counts, pH levels, and conducted rapid analyses using FTIR and MSI to evaluate salad quality over time.
  • - Results indicated that while pathogen levels increased in lettuce and rocket cabbage, they stabilized in cabbage, and the presence of FMCC-B281 enhanced the salads' shelf life by 1-2 days compared to control samples.
