Distribution of risk factor values for each spatial set of units.
^a A total of 52 slaughterhouses were present, handling poultry (n=24), ruminants (n=17) and/or swine (n=23). The “Others” category refers to areas having slaughterhouses handling ruminants or swine and might also include poultry slaughterhouses.
^b Not applicable (absence of areas with those values for the specific unit set).
