In our study, M. tuberculosis complex was detected only in
the bovine milk samples (13.3%). Previous studies have addressed
the identification of Mycobacteria in milk samples collected from
both individual and collective bulk tanks. In a study carried out in
Brazil, Mycobacterium spp. was detected from 8% of bovine milk
samples (Marília Masello Junqueira et al., 2013). Zoonotic tuberculosis
in human is attributed mainly to M. bovis and occasionally to
M. tuberculosis, which is mainly transmitted through milk. Therefore,
certain habits, such as the consumption of raw bovine milk,
may predispose individuals to these infections (Marília Masello
Junqueira et al., 2013).
