Science is often used as a political and economic bargaining chip in international talks on food safety, as seen in the recent dispute about beef between Taiwan and the US, a former US official said recently.
“The issues of agriculture and food safety are often used as chips for politicians. Unfortunately, I don’t think these things will stop in the foreseeable future,” Joseph Jen (任築山), an undersecretary for research, education and economics in the US Department of Agriculture (USDA) from 2001 to 2005, said in an interview on Friday.
“True science has been ignored so far,” said the 72-year-old scientist, who emigrated from Taiwan to the US in 1962 and retired last year as the dean of the College of Agriculture at California Polytechnic State University in San Luis Obispo.
Political and economic factors are usually placed above food safety in most international agricultural negotiations because most countries send diplomatic officials, rather than scientists, to handle the talks, Jen said.
The recent dispute between Taiwan and the US over imports of US beef is just one example of the complexity that arises when science is mixed with politics, he said.
The legislature passed an amendment in January last year that banned imports of selected beef products from countries, including the US, with documented cases of mad cow disease in the past decade.
That meant that US beef products seen as posing potential health risks, such as ground beef and organs, were barred from entering Taiwan, in contravention of a bilateral beef trade protocol signed by the two countries in October 2009.
Tensions over beef arose again this January, when US beef products found to contain residue of ractopamine — a feed additive used to promote the growth of lean meat that is banned in Taiwan — were taken off the shelves of local stores.
The move prompted the US to call off a long anticipated meeting under the Trade and Investment Framework Agreement, an official framework for Taiwan-US dialogue on trade and economic issues in the absence of diplomatic ties.
Jen said Taiwan’s decision last year was not based on scientific research because the probability of contracting mad cow disease by consuming US beef was lower than being hit by a car.
As for this year’s dispute, Jen said Taiwan cited the EU’s zero tolerance policy on ractopamine to justify the ban and would wait for the conclusions of a meeting of the Codex Alimentarius Commission in July that will set maximum residue levels for ractopamine, before reconsidering the issue.
However, even then, politics and science are mixing because the EU and the Codex both have been heavily influenced by politics, Jen said.
“Its [the Codex’s] science is politically approved science, not the real science,” he said, calling the EU “the main culprit” of mixing science with politics, starting with its condemnation of US-produced genetically modified organism products.
Food safety is a complicated issue because many people and processes are involved in the production chain, said Jen, who received his bachelor’s degree in agricultural chemistry from National Taiwan University in 1960.
“The keys for modern-day scientists are ‘probability’ and ‘risk assessment,’ because there is no such thing as a ‘zero risk.’ There is no magic wand that can solve anything in a blink of an eye either,” he said.
However, Jen said that it always takes a long time for scientists to conduct research and reach a consensus, and before that happens, every government gets to make its own policies and decisions.
“I don’t think I am in a position to recommend to Taiwan’s government what to do. I think it will do what it thinks is the best for the people of Taiwan,” said Jen, who was visiting Taiwan for the first time in 23 years.
He urged the media to play a positive role in promoting food safety and relaying accurate messages to people, because media reports too often cause panic by exaggerating negative effects.
A tropical depression in waters east of the Philippines could develop into a tropical storm as soon as today and bring rainfall as it approaches, the Central Weather Administration (CWA) said yesterday, while issuing heat warnings for 14 cities and counties. Weather model simulations show that there are still considerable differences in the path that the tropical depression is projected to take. It might pass through the Bashi Channel to the South China Sea or turn northeast and move toward the sea south of Japan, CWA forecaster Yeh Chih-chun (葉致均) said, adding that the uncertainty of its movement is still high,
TAIWANESE INNOVATION: The ‘Seawool’ fabric generates about NT$200m a year, with the bulk of it sourced by clothing brands operating in Europe and the US Growing up on Taiwan’s west coast where mollusk farming is popular, Eddie Wang saw discarded oyster shells transformed from waste to function — a memory that inspired him to create a unique and environmentally friendly fabric called “Seawool.” Wang remembered that residents of his seaside hometown of Yunlin County used discarded oyster shells that littered the streets during the harvest as insulation for their homes. “They burned the shells and painted the residue on the walls. The houses then became warm in the winter and cool in the summer,” the 42-year-old said at his factory in Tainan. “So I was
THE TOUR: Pope Francis has gone on a 12-day visit to Indonesia, Papua New Guinea, East Timor and Singapore. He was also invited to Taiwan The government yesterday welcomed Pope Francis to the Asia-Pacific region and said it would continue extending an invitation for him to visit Taiwan. The Ministry of Foreign Affairs made the remarks as Pope Francis began a 12-day tour of the Asia-Pacific on Monday. He is to travel about 33,000km by air to visit Indonesia, Papua New Guinea, East Timor and Singapore, and would arrive back in Rome on Friday next week. It would be the longest and most challenging trip of Francis’ 11-year papacy. The 87-year-old has had health issues over the past few years and now uses a wheelchair. The ministry said
