Maui doesn't have enough food safety inspectors.
Maui District Health Office program chief Patti Kitkowski told The Maui News there are only three inspectors for the entire county.
They're responsible for looking after more than 1,700 registered food establishments and temporary vendors that sell food on weekends or at special events.
The county hired two more inspectors from the mainland in recent years but Kitkowski says they left because of the high cost of living and low pay.
The FDA recommends that high-risk establishments be checked every four to six months. But Kitkowski says two years may pass between inspections on Maui.
She says the most common violations are lack of hand-washing, poor temperature controls, cross-contamination by raw or uncooked foods and vermin.
