Chiquita has warned it will continue to seek higher returns from its customers as it grapples with fruit cost increases.

Banana sourcing and production costs were expected to rise in 2009 as a result of high fruit prices, government-imposed exit prices and £20m of costs following flooding in Central America last year, it said.

Chiquita's sales are currently flat and last week it reported a £220m loss following a £256m non-cash goodwill impairment charge for Fresh Express.

It said it had also taken a tougher stance on pricing with foodservice customers in salads and healthy snacks sector under its "profit improvement" programme. "The company elected not to renew certain foodservice contracts with customers unwilling to accept certain price rises. As a result the company expects its foodservice volume could fall by as much as 50% in 2009," it warned.
