A mix of bacteria-killing viruses can be safely sprayed on cold cuts, hot dogs and sausages to combat common microbes that kill hundreds of people a year, US health officials said in granting the first-ever approval of viruses as a food additive.
The combination of six viruses is designed to be sprayed on ready-to-eat meat and poultry products, including sliced ham and turkey, said John Vazzana, president and chief executive officer of manufacturer Intralytix Inc.
The special viruses called bacteriophages are meant to kill strains of the Listeria monocytogenes bacterium, the US Food and Drug Administration (FDA) said on Friday in declaring it safe to use on ready-to-eat meats prior to their packaging.
The viruses are the first to win FDA approval for use as a food additive, said Andrew Zajac of the regulatory agency's office of food additive safety.
Serious infection
The bacterium the viruses target can cause a serious infection called listeriosis, mainly in pregnant women, newborns and adults with weakened immune systems. In the US, an estimated 2,500 people become seriously ill with listeriosis each year, according to the Centers for Disease Control and Prevention. Of those, on average, 500 die.
Luncheon meats are particularly vulnerable to Listeria since once purchased, they typically aren't cooked or reheated, which can kill harmful bacteria like Listeria, Zajac said.
The preparation of bacteriophages attacks only strains of the Listeria bacterium and not human or plant cells, the FDA said.
"As long as it used in accordance with the regulations, we have concluded it's safe," Zajac said. People normally come into contact with bacteriophages through food, water and the environment, and they are found in our digestive tracts, the FDA said.
Consumers will not be aware that meat and poultry products have been treated with the spray, Zajac added. The Department of Agriculture will regulate the actual use of the product.
Toxic
The viruses are grown in a preparation of the very bacteria they kill, and then purified. The FDA had concerns that the virus preparation potentially could contain toxic residues associated with the bacteria. However, testing did not reveal the presence of such residues, which in small quantities likely wouldn't cause health problems anyway, the FDA said.
"The FDA is applying one of the toughest food-safety standards which they have to find this is safe," said Caroline Smith DeWaal, director of food safety for the Center for Science in the Public Interest, a consumer advocacy group.
"They couldn't approve this product if they had questions about its safety," she said.
Intralytix, based in Baltimore, first petitioned the FDA in 2002 to allow the viruses to be used as a food additive. It has since licensed the product to a multinational company, which intends to market it worldwide, said Intralytix president Vazzana. He declined to name the company but said he expected it to announce its plans within weeks or months.
Intralytix also plans to seek FDA approval for another bacteriophage product to kill E. coli bacteria on beef before it is ground, Vazzana said.
Three cases of Candida auris, a fungus that can cause a yeast infection known as candidiasis in humans, have been reported in Taiwan over the past few years, but they did not display drug resistance, Centers for Disease Control (CDC) Deputy Director-General Philip Lo (羅一鈞) said yesterday. Lo made the statement at a news conference in Taipei, one day after the Washington Post reported that the potentially deadly fungus is spreading in US hospitals. The fungus was first discovered in Japan in 2009 and poses a danger to immunocompromised people, with an estimated mortality rate of 30 to 60 percent, Lo
‘DIRE’: Taiwan would not engage in ‘dollar diplomacy,’ the Ministry of Foreign Affairs said, after China reportedly offered Honduras up to US$3 billion to establish relations The government yesterday recalled its ambassador to Honduras after the Central American nation sent its foreign minister to China, signaling that it would sever diplomatic ties with Taiwan. Suspicions concerning ties with Honduras are rife after Honduran President Xiomara Castro on Tuesday last week wrote on Twitter that her country would pursue diplomatic ties with China.

MEDIA, SOCIETY FOCUS: Doublethink Lab said that Beijing is trying to coerce countries that rely on China economically to pursue policies in its favor China has stronger influence over Taiwan’s media and society than any other country, the Taipei-based Doublethink Lab think tank said yesterday, as it announced its China Index gauging Beijing’s global influence. Taiwan ranked 11th overall among 82 countries assessed, but first in terms of social and media influence, Doublethink Lab chairman Puma Shen (沈伯洋) told a news conference in Taipei. More than 200 experts and academics participated in the project, including some highly influential figures, Shen said. The index collects information from countries worldwide to gauge China’s influence and assess how Chinese policies affect them, Shen said. In terms of Chinese
