Abstract
Foodborne pathogens are a major contributor to foodborne illness worldwide. The adaptation of a more quantitative risk-based approach, with metrics such as Food safety Objectives (FSO) and Performance Objectives (PO) necessitates quantitative inputs from all stages of the food value chain. The potential exists for utilization of big data, generated through digital transformational technologies, as inputs to a dynamic risk management concept for food safety microbiology. The industrial revolution in Internet of Things (IoT) will leverage data inputs from precision agriculture, connected factories/logistics, precision healthcare, and precision food safety, to improve the dynamism of microbial risk management. Furthermore, interconnectivity of public health databases, social media, and e-commerce tools as well as technologies such as blockchain will enhance traceability for retrospective and real-time management of foodborne cases. Despite the enormous potential of data volume and velocity, some challenges remain, including data ownership, interoperability, and accessibility. This paper gives insight to the prospective use of big data for dynamic risk management from a microbiological safety perspective in the context of the International Commission on Microbiological Specifications for Foods (ICMSF) conceptual equation, and describes examples of how a dynamic risk management system (DRMS) could be used in real-time to identify hazards and control Shiga toxin-producing Escherichia coli risks related to leafy greens.Entities:

Figure 1A number of examples of the types of big data currently or potentially available across the leafy green food chain that can be integrated for use in traceback to determine implicated product source during outbreak situations, and can be used to inform dynamic risk management systems (DRMS).
Figure 2Stylized DRMS. Dynamic risk management involves the use of big data for quick identification of changing conditions resulting in potential changes to the hazard analysis and facilitates decision-making to manage those risks in real-time. (A) through (D) represent examples of how a DRMS could have been used to identify hazards and control Shiga toxin-producing Escherichia coli (STEC) risks related to leafy greens. (A) represents the baseline conceptual risk management in a fresh-cut leafy greens operation, where the initial hazard level, controlled by preventive measures during production is below the Food Safety Objectives (FSO), and (i) no introduction or cross-contamination occurs during harvest; (ii) there is a small reduction during washing, and (iii) potential increases in STEC populations are controlled by the cold chain. (B) represents STEC contamination of leafy greens during processing. The initial hazard level is controlled by preventive measures during production, and (i) no introduction or cross-contamination occurs during harvest, (ii) untreated water used during the wash step introduces a high level of STEC, and (iii) potential increases in STEC populations are controlled by the cold chain. In this case, DRMS would have had the real-time data surrounding the wash water (see Figure 1), flagged a concern, and allowed for risk management decision-making that could have prevented entry of this product into the supply chain. (C) represents STEC contamination of leafy greens during production. Due to a breakdown in pre-harvest preventive measures, the initial hazard level is higher than the baseline, which may be due to a combination of factors including (i) proximity of concentrated animal feeding operations (CAFOs), (ii) unusual weather patterns (i.e., winds and freezing), and/or (iii) contaminated water sources used in applications that contacted harvested product. For this scenario, (i) no introduction or cross-contamination occurs during harvest; (ii) there is a small reduction during washing, and (iii) potential increases in STEC populations are controlled by the cold chain. In this example, DRMS would have the real-time data around production practices (see Figure 1), flagged a concern, and allowed for risk management decision-making to prevent entry of this product into the supply chain. (D) represents a potential response to (C) using DRMS. When DRMS flagged a concern with production water use (see Figure 1), the risk management decision is made to treat the water (e.g., chemical treatment, UV light) that contacts the harvestable portion of the leafy greens (i.e., overhead irrigation, foliar sprays, and aerial sprays) prior to application to reduce the introduction of STEC from this source. The risk management decision to treat the irrigation water decreases STEC levels to below the FSO.
