  "term": "controllable variability",
  "field": "Environment",
  "definition": "Sources of heterogeneity of values of time, space or different members of a population that can be modified in part - in principle, at least - by intervention, such as a control strategy. For example, variability in the time and temperature history of food storage among storage devices influences variability in pathogen growth among food servings and in principle could be modified through a control strategy. For both population and individual risk, controllable variability is a component of overall variability. (FAO/WHO 2003b)",
