The Health Inspector (real name: Nadar Klessard) is one of the minor antagonists in Ratatouille.
Unlike most Pixar villains, the health inspector's antagonism is not based on outright hatred for the protagonists, but rather performing the job he was hired to do: inspecting restaraunts for cleanliness standards. When the rats are going to get him, they used coils of rope and tied him up, gagged his mouth shut with duct tape and put him in the food closet, along with a captured Chef Skinner. In the final scene, Remy says that there was no way the rats could have kept Skinner nor the health inspector detained indefinitely, and later had to free both of them.
Skinner calls the health inspector on a public phone outside Gusteau's to report a rat infestation. The inspector replies with him coming to check the restaurant in three months time. Skinner protests but the inspector promises a sooner visit if someone else cancels an inspection. When Skinner tries to protest again, the inspector hangs up on him.
On the next day, before Remy and the other rats start cooking, the inspector comes in the restaurant (presumably, the said other inspection was canceled), dropping his documents. Stunned by what he saw, he ran to his car, with Django and some other rats covering almost the entire car while he tries to start it. The car eventually starts, but crashes afterwards when Colette returns. Then, the health inspector is seen tied up and being thrown in the food locker by the rats. Near the end of the film, Remy says they could not keep the health inspector (nor Skinner) imprisoned in the food locker forever and were forced to release both of them, which ultimately led to the closure of Gusteau's for health violations.
- The inspector said that he will come within three months, and if someone cancels one inspection, he'll slot Skinner in. However, he comes to the restaurant on the next day, assuming the fact someone canceled the inspection.
- According to Ratatouille: The Junior Novelization, his real name is Nadar Lessard.
- The health inspector's car seems to have the same structure as a Smart Fortwo, but has round headlights.
- His car is electric.
