The risk assessment report of American pigs containing ractopamine was released.

Although Wayne thinks that the opening of American pigs containing ractopamine (commonly known as clenbuterol) is a political issue, not a food safety issue (see: importing fine lean pigs is a political issue, not a food safety issue), it must be based on the scientific basis of food safety. A few days after announcing the opening of the business, * * * finally released the risk assessment report. This "108 health risk assessment report on ractopamine exposure in edible meat" was completed by the Institute of Environmental Medicine/Environmental Trace Toxicology Research Center of Chengda Medical College.

How to report

The report is based on the data of the National Feeding Database of the United States, and is based on the number of beef/pig muscles and viscera consumed by all age groups every day. For the concentration of ractopamine in cattle, pork and their viscera, refer to the maximum residue of animal drugs in food and the maximum residue limit (MRL) of ractopamine in different parts of cattle and pigs proposed by the risk management recommendations of Codex Alimentarius Commission (20 18). The exposure value is calculated by other factors, and then compared with ADI (Acceptable Daily Intake) value formulated in the Republic of China 10 1 year, so as to make a comprehensive risk assessment.

Moreover, the intake above is strictly calculated, that is to say, it is assumed that cattle, pork and its products and internal organs are all imported and all contain ractopamine residues.

In order to evaluate all consumers, this evaluation is aimed at people of different ages and sensitive ethnic groups, including children, young children, teenagers, adults, the elderly and women of childbearing age and confinement.

Conclusion of risk assessment

Conclusion: The results show that the exposure dose of ractopamine at all ages is 2.6 ~ 9.2% of the acceptable daily intake of ractopamine (ADI) in China, so the risk is very low.

Only for confinement women who eat kidney and tonify their bodies, if it is assumed that confinement women eat a pair of kidneys and a pair of livers every day, then the exposure dose of ractopamine to confinement women accounts for 89.9% of ADI's, which is more risky, so it is still necessary to pay attention to eating too many internal organs.

Wayne added other relevant information.

Side effects of ractopamine

Contact with meat containing ractopamine may have adverse effects on the heart. Side effects of ractopamine: taking too much ractopamine will cause cardiovascular side effects, such as palpitation, elevated blood pressure and other cardiovascular problems, and may also cause symptoms such as nausea, dizziness and shaking hands. In addition, clenbuterol is also a banned drug in sports, so athletes should be careful.
