The Beijing Municipal Bureau of Market Supervision has fined Beijing Shengxiang Dairy Factory for selling 1,440 bottles of substandard plain yogurt. The yogurt had excessive yeast and mold, exceeding the permitted limits under the National Milk Standard. This is not the first time Shengxiang Dairy has been penalized for selling unqualified dairy products. In the past, they have recalled honey yogurt due to yeast contamination and were fined for selling honey yogurt with improper acidity. They have also been involved in a 'early milk' scandal where they misrepresented the production date of their products.
