Sales by Paul Newman's food company are up about 25 percent this year, partly because of the highly publicized civil suit against Newman, the actor said. Westport delicatessen owner Julius Gold's suit claims he was promised 8 percent of the stock of Newman's Own in exchange for his help in starting the company. Newman says the allegation is without merit. A four-week trial ended last summer in a mistrial. A new trial has not been scheduled. On Friday, Newman released a statement saying that net sales from his food products were $30 million from Jan. 1 through Oct. 31. He said sales were $24 million in the first ten months of 1987. Sales increased 28 percent during the trial, Newman's Own said. "Charity and good intentions sometimes triumph over bad taste and pastrami," Newman said in a statement.
