Zhang Ji Guandong paper boiled bowl was investigated: 3-Chloropropylene glycol exceeds the standard cancer risk warning
Recently, food safety issues have once again attracted public attention. The well-known chain brand "Zhang Ji Guandong Chuan" was reported by the market supervision department because it was detected that 3-chloropropylene glycol exceeded the standard in a paper bowl, and related topics quickly topped the hot search list. 3-chloropropanediol is a potential carcinogen, and long-term intake may increase cancer risk. This article will combine the hot data of the entire network for the past 10 days to sort out the incident process and analyze the deep causes of food safety issues.
1. Event review
According to the random inspection report released by the State Administration for Market Regulation, the content of 3-chloropropylene glycol in some paper bowls used by Zhang Ji Guandong boil is as high as 1.2mg/kg, exceeding 140% of the national standard limit (0.5mg/kg). This substance mainly comes from the high temperature degradation of oils and fats in food packaging materials or the residue of processing additives. The following are the key data of the sampling results:
| Testing items | National standard limit | Actual measured value | Exceed multiples |
|---|---|---|---|
| 3-Chloropropanediol | 0.5mg/kg | 1.2mg/kg | 1.4 times |
| Epoxy propyl alcohol | No detection | Not detected | - |
2. Analysis of public opinion data across the network
After the incident was exposed, the number of social media discussions exceeded 500,000 within 24 hours. The following are the dissemination trends of related topics in the past 10 days:
| date | Readings on Weibo | Short video platform playback volume | Media coverage |
|---|---|---|---|
| May 1 | 12 million | 8.5 million | 68 articles |
| May 3 | 43 million | 21 million | 152 articles |
| May 5 | 68 million | 35 million | 287 articles |
3. Experts interpret health risks
Li Guoqiang, professor at the School of Food of China Agricultural University, pointed out: "3-chloropropylene glycol is a Class 2B carcinogen. Short-term exposure will not cause disease immediately, but long-term intake will increase the risk of digestive tract tumors." The daily tolerated intake recommended by the World Health Organization is 2μg/kg body weight. Take an adult of 60kg as an example:
| Intake scene | Single contact amount | Weekly safety cap |
|---|---|---|
| 1 serving of Kanto cooked daily | 18μg | 7 servings |
| Exceeding products exceeding the standard | 43.2μg | 2 servings |
4. Corporate response and industry impact
Zhang Ji Guandong Zhuo’s official Weibo account issued a statement saying that the batch of paper bowls involved had been removed immediately and promised to conduct a comprehensive investigation of stores across the country. It is worth noting that this is the third food packaging safety incident in the past three months:
| time | The company involved | Problem substance | Exceeding the standard range |
|---|---|---|---|
| February 2024 | A milk tea brand | Phthalate | 2.1 times |
| April 2024 | A fast food chain | Fluorescent whitening agent | Detection limit |
5. Consumer protection advice
1. Avoid reuse of disposable paper bowls
2. Try to choose ceramic or stainless steel containers for high-temperature foods
3. Pay attention to whether the packaging has a "food contact" logo
4. Stop using immediately if abnormal odor or leakage is found
This incident exposed that there are still blind spots in the supervision of food packaging materials. Experts call for the establishment of a full life cycle traceability system for packaging materials, and at the same time suggest that consumers actively report suspicious products through the 12315 platform. Food safety is no small matter, and it needs to be jointly protected by enterprises, regulatory departments and consumers.
