"The first set is outbreak contributing factors—the practices that most likely led to contamination, proliferation, or survival of agents in the environment (Centers for Disease Control and Prevention, 2023). The second set is environmental antecedents, hereafter referred to as antecedents, of the outbreak. Antecedents are the circumstances and situations that led to the contributing factors. For example, an investigation may identify the contributing factor to a norovirus outbreak as contamination of food by an ill employee, and the antecedent as insufficient staffing, which led to the employee not being allowed to stay home while ill."
"Identifying the contributing factors and antecedents is essential to understanding the outbreak’s root cause and implementing sustainable corrective actions to stop the outbreak and future outbreaks (Firestone et al., 2018)."
The two biggest environmental antecedents were 1) lack of training of employees for specific purposes and 2) lack of oversight of employees / enforcement of policies.
From the text, Table 3 and 5 were most interesting.

Abstract
Foodborne outbreak investigations often provide data for public health officials to determine how the environment contributed to the outbreak and on how to prevent future outbreaks. State and local health departments are responsible for investigating foodborne illness outbreaks in their jurisdictions and reporting the data to national-level surveillance systems, including information from the environmental assessment. This assessment is designed to describe how the environment contributed to the outbreak and identifies factors that contributed to the outbreak and environmental antecedents to the outbreak. Environmental antecedents, also referred to as root causes, are specific reasons that allow biological or chemical agents to contaminate, survive, or grow in food. From 2017 to 2019, 24 jurisdictions reported 1,430 antecedents from 393 outbreaks to the National Environmental Assessment Reporting System. The most reported antecedents were lack of oversight of employees/enforcement of policies (89.1%), lack of training of employees on specific processes (74.0%), and lack of a food safety culture/attitude towards food safety (57.5%). These findings highlight the critical role that employees play in restaurant food safety and are heavily influenced by restaurant management, who can exercise active managerial control to manage these antecedents. Identifying antecedents during investigations is essential for understanding the outbreak’s root cause and implementing sustainable corrective actions to stop the immediate outbreak and future outbreaks.
