Documents from the Codex Alimentarius Commission regarding safe levels of residues of the leanness-enhancing drug ractopamine in meat show the commission’s discussions have centered on scientific evidence, contradicting claims by officials from the Chinese Nationalist Party (KMT) government that the issue has been affected by protectionist trade interests.
Government officials recently made repeated attempts to decouple the proposed plan to accept an allowable level of ractopamine residues in US beef imports from the highly likely event that the Codex could once again fail to ratify a proposed residue standard when the UN’s food safety agency meets on July 2 for its annual session.
Characterizing the issue as “a trade war” between the US, an active proponent of the use of ractopamine mainly in cattle and pigs, and the EU, leading a strong opposition to it, officials led by Executive Yuan spokesperson Hu Yu-wei (胡幼偉) said that discussion of ractopamine at the Codex was not and would not just be about science and health.
The claims were not confirmed by the Codex’s official record of proceedings of meetings at which the issue had received extensive discussions over the years involving many countries of the 185-member organization.
Since the Joint Expert Committee on Food Additives (JECFA), which serves as a scientific advisory body to the UN’s Food and Agriculture Organization and the WHO, advanced its draft study on maximum residue levels (MRLs) for ractopamine to the Codex commission for adoption in 2008, the final step in the eight-step Codex approval process, the proposal has been held for four consecutive years.
The reasons the EU opposes the adoption of the draft MRLs were mainly articulated in its report conducted by the European Food Safety Authority to review the JECFA study.
Presented to the Codex commission at its session in 2010, the EU report concluded that it was impossible to derive an accepted daily intake from the data submitted by the JECFA and that therefore no proposal for MRLs could be made.
The EU repeatedly underlined that it highly respected the work of the JECFA, but could not ignore the opinions provided by their own risk assessment body, which is at the basis of their food safety system established according to the principles of risk analysis.
China, also a strong opponent of the use of ractopamine, first reported on its residues studies to the Codex commission in its 2009 session, saying it was very cautious in this regard because it had seen cases of food poisoning from the consumption of tissues containing residues of beta-agonists, the class of drug to which ractopamine belongs.
Studies conducted by China showed residue levels in muscle, liver, kidneys, and lungs exceeded the draft MRLs proposed by the JECFA and emphasized that internal organs are regularly consumed in China and other Asian countries.
The Codex documents showed that countries joining the EU and China in opposition to the draft proposal were Norway, Kenya, Singapore, among others.
At the 2008 Codex session, Singapore expressed its concerns over relying on veterinary drugs rather than fostering genetic improvements to increase gross weight and leanness of livestock, one of various delegations that noted that veterinary drugs should be used only when necessary, and taking into consideration aspects of animal health and animal welfare.
At a meeting held by the JECFA on the issue last year, Kenya said further research should be carried out on lungs, hearts and intestines to establish MRLs for safety purposes.
The documents showed that China had submitted at least four studies with regard to its concerns over higher levels of ractopamine residues in offal to the Codex in 2009 and 2010, to which the JECFA responded in Codex session in 2010 and last year.
At the 2010 session, the JECFA dismissed China’s concerns after it reviewed its studies and dietary information, concluding that ractopamine residues in muscles, fat, liver, kidney and other offal had been considered and that no health concerns had been identified.
The JECFA said in 2010 that the only possible dietary source that could lead to consumption of residues above the acceptable daily intake was lung tissue, if considerable amounts were consumed on a regular basis.
Last year, the JECFA further dismissed concerns over lung tissue, saying consumption of lung tissue containing ractopamine residues did not indicate a health concern because consumption of lung tissue and other non-standard tissue generally replaced consumption of muscle, and were not added to the daily consumption of animal products.
The long delay in adopting the draft MRLs was also a concern of Brazil, Australia and the Philippines, among others, some of which were among the 27 countries in the world which permitted ractopamine residues in locally produced or imported meat products.
At last year’s session, the US called for a roll-call vote on the adoption of the draft MRLs.
Given that the US motion deviated from the Codex’s normal practice, in which its members decide food-safety standards by consensus, a roll-call vote on whether to proceed with a vote on adoption of the MRLs by a secret vote was first held, and then a secret vote was held to determine whether the draft MRLs should be voted on.
The first vote saw that 64 voted in favor of a secret vote, with 54 against and 6 abstentions. Japan, one of the 27 countries that permits ractopamine residues, did not side with the US, which voted in favor of a vote on the draft MRLs being held by a secret vote.
In the second vote, 59 voted in favor of holding a secret vote on the draft MRLs, but 68 voted against, with 9 abstentions, leaving the issue to be decided next month.
FLU SEASON: Twenty-six severe cases were reported from Tuesday last week to Monday, including a seven-year-old girl diagnosed with influenza-associated encephalopathy Nearly 140,000 people sought medical assistance for diarrhea last week, the Centers for Disease Control (CDC) said on Tuesday. From April 7 to Saturday last week, 139,848 people sought medical help for diarrhea-related illness, a 15.7 percent increase from last week’s 120,868 reports, CDC Epidemic Intelligence Center Deputy Director Lee Chia-lin (李佳琳) said. The number of people who reported diarrhea-related illness last week was the fourth highest in the same time period over the past decade, Lee said. Over the past four weeks, 203 mass illness cases had been reported, nearly four times higher than the 54 cases documented in the same period
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
