Salmonella, E. coli and thermotolerant coliforms were not
detected in any of the 120 chocolate samples. In company A, six out
of 15 samples of milk chocolate, five of dark chocolate and five of
white chocolate showed Enterobacteriaceae count, ranging from
1.00 to 1.70 log cfu/g. In one sample of 70% cocoa chocolate a count
of 2.36 log cfu/g was observed. Total coliforms were isolated from
six samples of milk chocolate, two of dark chocolate, one of white
chocolate and one of 70% cocoa chocolate (Table 2). In company B,
Enterobacteriaceae was detected in nine samples (52.9%) of milk
chocolate, one (7.1%) of dark chocolate and two (13.3%) of white
chocolate, with counts between 1.0 and 1.8 log cfu/g. One out of 13
light chocolate samples showed a count of 2.27 log cfu/g. In regard
to total coliforms, the same number of contaminated samples (2)
was shown for milk, white and light chocolate (Table 3).
