MADRID, Oct 9 (Reuters) - The world's largest olive oil maker, Spain's Deoleo, has hired investment bank Lazard to seek strategic options including a potential sale, it said on Monday in a filing to the stock market regulator.

Adverse weather in Spain has led to an olive oil output drop in the country which accounts for about 40% of global output.

The company, whose main shareholder is buyout fund CVC, said two weeks ago it had plunged in the red in the first half of this year after posting a small profit a year earlier.

Deoleo, with such brands as Bertolli and Carbonell, has denied it was in talks with United Arab Emirates' IFFCO as was recently reported by El Economista newspaper. (Reporting by Inti Landauro, editing by Andrei Khalip)
