ITALY'S BUITONI ACQUIRES VISMARA FOOD GROUP Carlo De Benedetti's food company Industrie Buitoni Perugina Spa said it has acquired the Italian food group Vismara. Buitoni said in a statement that Vismara had 1986 sales of 181 billion lire and net profit of 11 billion lire, employs 950 people and has four subsidaries. Buitoni did not disclose financial details about the acquisition. De Benedetti said last week that his group was negotiating a purchase of an unidentified Italian food firm. Vismara primarily produces a variety of pork products. "The acquisition represents a diversification in a market sector with annual consumption of 8,500 billion lire," Buitoni said. Buitoni also said its consolidated revenue during the first quarter of this year was 429 billion lire, up 51 pct from the comparable 1986 period. As reported, Buitoni's consolidated revenue rose last year to 1,623 billion lire from 1,177 billion in 1985. Net profit rose to 18.5 billion lire from 448 mln lire in 1985.
