FDA approves using viruses to treat meat

WASHINGTON – 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, federal health officials said Friday 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 Food and Drug Administration said 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.

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 – the name is Greek for “bacteria-eater” – 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 phages through food, water and the environment, and they are found in our digestive tracts, the FDA said.

Consumers won’t 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.

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 CEO Vazzana.

Intralytix also plans to seek FDA approval for another bacteriophage product to kill E. coli bacteria on beef before it is ground, Vazzana said.
