Some other cases of contaminated food in China have been exposed recently. Consumer confidence has once again been shaken. Many people are calling on the government to strengthen their supervision and administrative sanctions on food products.

To use pork to make beef? This miracle has been widely found in China this April. By adding this kind of additive called "beef extract," pork can be processed to become as tasty, and expensive as beef.

It seems this additive is not a secret in the market, only the consumers don't know.

Medical Expert, said, "People keeps absorbing excessive additives over a long time, their kidneys and livers will be damaged. And it will damage the neural system of chidren and old people."

While the consumers are still shocked by this so-called beef, buns on their dining table have also dealt them another blow.

An initial investigation by the municipal government has revealed that the Shanghai Shenglu Food Company produced more than 3-thousand steamed buns daily using additives to make them appear fresher. These were then sold across the city, including in some large supermarkets.

Fewer steamed buns were for sale at this Lianhua supermarket. More than 32-thousand buns were taken off store shelves when the scandal emerged.

Mr. Wang, Sales Manager of Lianhua Supermarket, said, "We removed the steamed buns produced by Shenglu as soon as we learned of the incident. We gave customers who had bought the steamed buns from our outlets refunds with their receipts. Despite the scandal, our sales volume has been fine so far."

However, most customers remain concerned about food safety. Steamed buns are a regular breakfast staple for Ms. Gao. She used to buy them mostly from supermarkets because she felt it was a clean and safe environment. But now, she has second thoughts about buying the popular snack.

Ms. Gao, Shanghai Shopper, said, "I can't believe that even steamed buns from the supermarket are no longer safe. The only places I trusted to shop at were major supermarkets and specialist shops. But now even there, product quality cannot be guaranteed. I really don't know where to buy my goods from in the future."

Two years ago, China enacted a Food Safety Law. Although difficulties were unresolved and controversies remained, many were hopeful it would deal with the country's bad record on food safety. But now it seems the law needs to be perfected and better enforced.
