an epidemiological study of listeriosis in dairy cattle

of disease. Similarly storing feed straw covered outside was also associated with an
increased risk of disease (OR 3.23, CL 0.97-10.09) (Table 3. 9).
(iv) Housing:
a) Type of housing: Housing animals in houses other than loose yards or cubicles was
associated with a decreased risk of disease in milking cows but this was not statistically
significant (OR 0.16, CL 0.01-1.12) (Table 3. 11).
b) Use of bedding: Straw bedding in other types of houses was also associated with a
decreased risk of reporting disease (OR 0.0, CL 0.0-0.95) (Table 3. 11).
