Each officer was sentenced to 624 years in prison for using deadly force to quell a fight among inmates. The court found the officers guilty of killing 52 prisoners.
A seven-person jury reached the sentence, which was read out by the presiding judge today.
The sentence was reached after a week-long trial, the second part of a process broken into four in which 79 military police officers are on trial for the death of the Carandiru prisoners.
At the time of the massacre Carandiru had 8,000 inmates and was the largest prison in Latin America.
