RACHAEL RAY – who has battled severe respiratory health problems – is fuming after discovering her luxury Hamptons home is infested with dangerous mold.

The TV chef’s lawyer-husband, John Cusimano, has filed a lawsuit in New York State Supreme Court against two home inspection companies – Amerispec Heritage Home Inspection Service and Joseph Schmitt Consulting Engineers – alleging they failed to spot the mold and water damage before he and Rachael bought the property. He’s asking for $3 million in damages.

The couple purchased the five-bedroom, five-bathroom villa on Long Island, near the exclusive town of Southampton, for $2.9 million in 2007.

Rachael has revealed that she suffered from bouts of croup when she was a child, which left her with her distinctive husky voice. She’s worried that her moldy home could wreak havoc on her health, say sources.

Rachael and John have spent little time there, instead staying at their apartment in New York City.

According to the Centers for Disease Control and Prevention, studies have found that indoor mold can lead to "upper respiratory tract symptoms, cough and wheeze in otherwise healthy people."

And it’s all the more serious for Rachael because she has been recovering from treatments to reduce growths on her vocal cords, said an insider.
