Snow Brand Milk Products Co. announced Wednesday that it will resume milk production at six of its 20 factories that were closed earlier this month after a major food-poisoning outbreak.

The Health and Welfare Ministry decided Tuesday to allow the company to resume production on condition that the firm does not recycle milk once it has been packed in cartons.

The six plants -- located in Sapporo, Aomori, Tokyo, Nagoya, Kobe and Fukuoka -- will resume production as early as today, the Tokyo-based major producer of dairy products said.
