Meiji Seika Kaisha Ltd. said Wednesday it will increase to 28 the types of confectionery and food products it will recall because they contain banned flavoring agents.

The company announced Monday it is recalling 19 types of products that contain the banned additives manufactured by Kyowa Perfumery & Chemical Co. of Tokyo.

A subsequent in-house investigation found the banned agents are also used in nine other types of confectionery and dietary supplements, it said.

These include Pokemon caramel, Apollo ice cream and milk cocoa, Meiji Seika said.

As a result of these additions, the company said it will recall 2.4 million packages of confectionery and foodstuffs worth a combined 300 million yen.

It also said it was going to put a notice in newspapers Thursday to inform consumers of its recall methods and other details.

Meanwhile, Kanebo Foods Ltd., a wholly owned subsidiary of Kanebo Ltd., said it will recall its Strawberry Short chocolate, which contains the banned additives.

More than 20 food manufacturers said by Tuesday that they are recalling products that contain the banned ingredients made by Kyowa Perfumery.

The agents — acetaldehyde, propionaldehyde and castor oil — were manufactured at its Ibaraki Prefecture factory.

The Food Sanitation Law bars food makers from using these substances in food.
