University of Maryland
JIFSAN-CFS³
Advisory Council Annual Symposium
Environmental Impact on Food Safety
The Hotel at the University of Maryland
College Park, Maryland USA
October 4–5, 2023
Symposium Background
There are a number of environmental factors that can have a significant impact on food safety and the supply chain. Microbial and chemical contaminants within the water supply are a key area of focus within our agricultural and manufacturing environments. In recent years, the focus of water quality and the impact on food packaging and sustainability have been driven by both regulatory changes and consumer expectations. The purpose of this symposium is to discuss our current understanding of the impact of the environment on our food supply with a focus on food, beverages, and packaging. The development of sustainable packaging technologies and challenges in the testing landscape will also be addressed. Speakers will provide a holistic view of the challenges, solutions and future steps that can be taken to close our existing knowledge gaps. The session will conclude with a discussion of how these often-complex, technical issues can best be communicated to stakeholders including consumers.
