Models that predict bacterial growth in food products can help industry with decision-making with regard to microbial food spoilage. Such models have recently been developed using machine learning (ML) rather than a mechanistic understanding of bacterial growth. Thus, our aim was to compare the performance of mechanistic (M) models and the Gaussian process (GP) model (i.

Article Synopsis
  • Fresh produce can be contaminated with Listeria monocytogenes at various points in the supply chain, especially in retail environments where limited assessment tools exist for controlling its spread.
  • Researchers developed an agent-based model to simulate Listeria transmission in a retail store's produce section to identify effective environmental sampling and control strategies.
  • The model highlights key factors influencing Listeria prevalence, suggesting that improving supplier controls and reducing contamination from consumers could significantly lower the risk of contamination in fresh produce.

In recent years, there have been numerous recalls of frozen vegetable products due to Listeria monocytogenes contamination, which causes listeriosis. In pregnant women, listeriosis can cause miscarriage, stillbirth, and other serious complications. Manufacturing guidelines are created with the intention that frozen vegetables will be cooked prior to consumption.

Article Synopsis
  • The Epstein-Barr virus (EBV) infects immune cells called B cells, helping them grow and change in a way that can lead to cancers called lymphomas.
  • A key protein from the virus, called EBNA2, boosts the production of a special substance (NAD) that B cells need to grow properly.
  • When doctors found this process in infected B cells of transplant patients, they realized it could be a target for new treatments to fight EBV-related diseases.
