Carnation Co. issued a voluntary recall of its Bon Bons brand ice cream and frozen Fruit Scoops after evidence was found of contamination by a potentially deadly bacteria, company officials said yesterday.

The recall covers "all flavors and sizes" of the Bon Bons and frozen fruit treats, although Food and Drug Administration inspectors detected the presence of listeria monocytogenes bacteria in only five batches, Carnation spokesman Dick Curd said.

"We decided to withdraw all flavors and sizes, acting on the side of safety," Curd said.

So far, no illnesses or infections have been reported, but listeriosis is especially dangerous to pregnant women, the elderly and the chronically ill. Symptoms of the disease may be a mild, flu-like illness or severe illness with fever, abdominal pain, headache, nausea and vomiting.

Most of the Carnation products affected by the recall were distributed east of the Mississippi River.

The bacteria was found in the batches bearing the following codes on carton bottoms:

Twenty-count Vanilla Bon Bons 8-133-7-24-11 and 8-335-6-24-11. Thirty-five-count Vanilla Bon Bons 8-154-7-24-11. Twenty-count Bavarian Mint Bon Bons 8-322-6-24-11 and 8-344-6-24-11.

Carnation said that the products may be returned to stores for a refund.
