When you buy seafood in the farmers' market, do you understand that the black plastic bag packaging seafood will cause harm to the body? Recently, some consumers have reflected that the black plastic bags used to buy seafood in the market a few days ago found an existing odor after taking home. When the author then visited several farmers' markets in Yantai city, Shandong province, he found that most seafood vendors were still using black plastic bags. Industry insiders said that most of the free black plastic bags provided by farmers' market vendors contain harmful substances and are not suitable for holding food, and citizens should refuse to use them.

Vendors: Black plastic bag capacity is large and durable

Recently, the author in Yantai Happy River market, dividend market and other wet markets to see, almost every seafood vendors will be placed in a prominent position black plastic bags. When the author proposed to buy seafood, most of the stall owners put the seafood directly into the black plastic bag after weighing. "The black bags are big and strong." A seafood vendor told the author that the use of black plastic bags in seafood stalls is decided by the market, because fresh aquatic products are easy to puncture with thin plastic bags and are not easy to carry. To this end, stall owners generally give priority to black plastic bags, which are not easy to puncture, and the quality is more guaranteed.

During the visit, the author found that colorless and white plastic bags are also used. Some seafood vendors use these plastic bags to pack the seafood before placing it in larger black plastic bags. Most consumers have no objection to the fact that fresh seafood is often packaged in black bags. And when asked whether they know that black plastic bags are of poor quality and contain harmful substances, most of the answers are no.

When I was about to leave the Happy River market, I saw two citizens buying shrimp and a stall owner theorized because of plastic bags. "Don't use black bags, black bags smell too strong." When the stall owner was about to bag, Ms. Zhang, who lives in the New World Garden, rushed to stop it. When a woman next to her saw it, she also said the black plastic bag smelled bad and asked the stall owner to use a white plastic bag. Ms. Zhang told the author that a few days ago to buy shrimp here, on the way home, you can smell the odor from the black bag, "At first I thought that the shrimp was bad, back to the market after a comparison, only to find that the taste comes from the black plastic bag of shrimp."

Quality supervision: black plastic bags contain harmful substances

Whether the black plastic bags provided by the market stalls have adverse effects on food and the human body? The author interviewed Yantai City quality Supervision Bureau food section chief Yu Zhongbo. He said that most of the black plastic bags in the farmers' market are the use of waste packaging film, packaging bags and other poor quality waste plastic processing, adding a large number of dark pigments to cover up, and the coloring agent contains toxic substances. If the raw materials have been loaded with chemical fertilizers, pesticides and other toxic and harmful substances, these substances can not be cleaned by washing. If the black plastic bag is used to package cooked food, toxic substances will penetrate into the food through the fat in the food, and the vegetables, meat and seafood sold in the farmers' market are food raw materials, and the harmful substances will also penetrate for a long time, causing harm to the human body. "China's" Measures for the Administration of Hygiene of Plastic Products and Raw Materials for Food "clearly stipulates that where plastic utensils, containers and food packaging materials are processed, recycled plastics shall not be used. According to the regulations, non-toxic, biodegradable and environmentally friendly packaging materials or bags should be used for food packaged in wet markets, such as fresh meat, fish, soy products and sauces, Yu said. Recycled packaging materials and black or dark toxic thick plastic bags should not be used. In order to ensure the safety of food plastic bags, the quality supervision department controls the source link, only the enterprises that obtain the production qualification of food plastic bags can produce food bags, and the standardized food bags should be marked with the "QS" mark. The black plastic bags used in the farmers' market absolutely do not meet the standards for food.

Yantai City Quality Supervision Bureau staff remind the public, when buying food, should refuse to use black or color plastic bags, it is best to bring their own bags, as little as possible to use the plastic bags provided by vendors.
