AGRICULTURE REPORT –August 20, 2002: Exploding Meat

By George Grow
This is the VOA Special English AGRICULTURE REPORT.

American scientist Morse Solomon has developed an unusual method to make meat softer. First, put a kilogram
or more of firm meat in a container filled with water. Add a small amount of explosives. Then, mix carefully and
explode.

No, Mister Morse is not attempting to destroy the meat. Instead, he is making it softer and
also killing¹ harmful bacteria. Mister Solomon is a meat scientist with the United States
Agricultural Research Service. He began to explore the use of shock waves to soften² meat ten
years ago. His method is called the Hydrodynamic Pressure Process. The theory is simple.
Shock waves from an explosion travel through water to the meat.

The shock waves tear small pieces of muscle and other particles away from the meat. This
makes the meat softer and easier to eat. The shock waves also reduce the amount of bacteria
in the meat. The Department of Agriculture says the process could increase food safety for
companies that sell meat.

Uncooked meat may contain organisms such as the Escherichia coli (esh-eh-RICK-ee-ah Staton of the
COLE-eye) bacteria, also known as E. coli. E. coli can make people sick if they eat meat that Tenderwave
is not well cooked. The Hydrodynamic Pressure Process may help reduce concerns about company prepare
harmful bacteria in meat. a test.

Other American scientists attempted to improve the process. They used a thick-walled metal container that was
buried in the ground. This device did not improve the quality of the meat as much as the simpler method.
However, the scientists found there seemed to be fewer bacteria in the meat than before the process.

Scientists had demonstrated that the Hydrodynamic Pressure Process could improve large pieces of meat. Next,
they wanted to see if the process reduced bacteria levels in smaller pieces of ground beef that is used to make
hamburgers. Their tests showed a reduction of bacteria in ground beef products. Other studies showed that
ground beef containing E. coli had no measurable levels of the bacteria after the treatment.

The Hydrodynamic Pressure Process does not kill all bacteria in the meat, however. Mister Solomon says some
good bacteria remain. The agricultural scientists say more studies are needed to see if the method could be used
in the meat processing industry.
