"Bachelor in Paradise" producers aren't taking any chances of drunken, nonconsensual sex ... because they've imposed new drinking rules on the cast.

Production sources tell us there is now a 2 drink max per hour. We're told the crew is monitoring drinking levels among the cast and the bartenders are also responsible for keeping tabs.

Producers have also made a point of providing food at all times during the shoots ... presumably to absorb the alcohol.

We're told the cast got a talkin' to over the whole Corinne/DeMario situation, both on and off camera, and drinking was a big talking point.

We're told they're a few days in, and so far, nothing too crazy ... which is not necessarily a good thing on 'BIP.'
