Karl Matthews, Ph.D., Professor of Microbial Food Safety at Rutgers University, discusses ways to eliminate pathogens like Salmonella, E. coli O157:H7 and Listeria from fresh fruits and vegetables. He highlights the importance of preventative measures from farm to table, including the use of water antimicrobials, like chlorine, and photosensitizers, like curcumin. Watch this episode: https://youtu.be/6Wkef9RyUVE Ashley's Biggest Takeaways We consume billions of microorganisms in the food that we eat each day. Fresh fruits and vegetables that are not thermally processed are likely to carry a higher microbial load than cooked foods. Many of those microbes are not concerning to human health. However, when pathogens of human health concern are present, the food can become unsafe to eat. Scientists use many methods from pre-harvest through post-harvest to keep food free of human pathogens. Water antimicrobials, such as chlorine, and photodynamic inactivation using photosensitizers, such as curcumin, are 2 prevent

Saeed Khan, Ph.D., Head of the Department of Molecular Pathology at Dow diagnostic research and reference laboratory and President of the Pakistan Biological Safety Association discusses the importance and challenges of biosafety/biosecurity practices on both a local and global scale. He highlights key steps for biorisk assessment and management and stresses the importance of training, timing and technology. Ashley's Biggest Takeaways Adequate biosafety and biosecurity protocols depend on a thorough understanding of modern challenges, and scientists must be willing and able to respond to new technological threats appropriately. In the microbiology lab, the threat goes beyond the physical pathogen. Implications of genomics and cyber security must be built into biorisk management techniques, including data storage and waste management practices. Risk assessments involve evaluation of both inherent and residual risk. Inherent risk is linked to the pathogen. Residual risk varies according to the lab, equipment,
