U.S. Scientists Discover Natural Agent That Kills Bacteria in Food

MINNEAPOLIS – U.S. scientists discovered a naturally-occurring agent that destroys the bacteria that cause meat, fish, eggs and dairy products to rot.

Researchers at the University of Minnesota reported the discovery of bisin -- a naturally-occurring compound produced by some types of bacteria.
The agent reduces the growth of bacteria including E. coli, salmonella and listeria and could lead to sandwiches that stay fresh for more than a year, The (London) Sunday Times reported.

The discovery also means that opened wine and products such as fresh salad dressing could last much longer -- in some cases for as long as several years. It could also lead to a reduction in the amount of food wasted and thrown away each year.

Bisin was discovered by University of Minnesota microbiologist Dan O'Sullivan. "It [bisin] seems to be much better than anything which has gone before," O'Sullivan said. "It doesn't compromise nutrient quality. We are not adding a chemical -- we are adding a natural ingredient."

Because bisin is chemically related to nisin, which is used to keep processed cheese sterile and edible for decades, it does not need to be pharmaceutically tested and could be on the market within a year.

I can just see it; "Hand me that half loaf of wheat bread I bought last year, will you?" Or "We better finish off that casserole before it goes bad. It's already 2 years old."

Pardon my suspicious mind, but this sounds like something that the Big Food Companies would buy, and then kill. After all, food lasting longer would mean we buy less, and would cut into their profits......

I ain't no doctor or scientist but I wonder....
If that stuff kills bacteria....I wonder what the long term effect would be on the human digestive tract?
Makes me nervous!

I agree, Hoot. The natural flora in our digestive systems are bacteria, this needs to be looked into more thoroughly.

Perhaps this only kills aerobic bacteria?
That would be sweet.

it's a "relative" of nicin - which is FDA approved and in use for years, apparently.

but close is not "the same" and indeed, I think I'll hold off . . .

oh, it's most effect against gram-positive bugs. which is only a small part of the bug universe.
