  Using QSAR, we're on the fly."
  Premarket review of food-contact substances,
  With these methods, they made advances.
  
  Nowadays, they're using multiple software,
  Taking their research to the next level, they dare.
  Metabolism data, predictive models too,
  In their QSAR evaluations, they're breaking through.
  
  Check it, this article's gonna give you the scoop,
  OFAS programs and how they make the loop.
  Using multiple QSAR tools, it's the way to go,
  Reviewing new food-contact substances, yo!
