Talk Description
Introduction: The Food Safety Modernization Act (FSMA) was enacted in 2011 to emphasize the prevention of foodborne illnesses in the food system. Within FSMA, the Produce Safety Rule (PSR) was the first rule with federal regulatory standards established for produce activities. One of the major components of the PSR is cleaning and sanitation in produce handling environments. To accommodate a wide variety of operations and equipment used, the regulation uses general terms for cleaning and sanitizing requirements, such as "adequately cleaned..." and "...when necessary and appropriate, sanitize...", which can be left to interpretation as to what constitutes adequately cleaned surfaces. Within the food industry, adenosine triphosphate (ATP) bioluminescence assay can be used to verify surface cleanliness, based on the reactivity of the luciferin-luciferase reagent with any ATP residue, resulting in light being emitted and measuring the presence of organic matter. ATP luminometer companies have set general thresholds of relative light unit (RLU) requirements, but there is lack of data on what these values mean in practice within different produce commodities and their environments.
