LOS ANGELES, May 11 (Xinhua) -- U.S. researchers have found MRSA (methicillin-resistant Staphylococcus aureus) in meats sold at U.S. supermarkets, according to a study published on Wednesday.This is "community-acquired MRSA" that is transmitted by humans carrying the bacteria, researchers at Wayne State University in Detroit reported in the study appearing in the May 11 online edition of the U.S. Centers for Disease Control and Prevention's ( CDC's) journal Emerging Infectious Diseases.For the study, the researchers purchased 289 raw meat samples, including 156 beef, 76 chicken and 57 turkey samples, from 30 grocery stores in Detroit from August 2009 through January 2010.The researchers found that 22.5 percent of the samples were contaminated with S. aureus and six samples tested positive for MRSA.Of the six samples contaminated with MRSA, two were beef, three were chicken and one was turkey, the researchers said.The extent of MRSA contamination in meat varies by the type of meat and where the meat was processed, said lead researcher Yifan Zhang, an assistant professor in the department of nutrition and food science at the university.The germ is apparently being introduced by humans handling the meat, she said.According to another recent study, the strain of MRSA in meat in the United States is not the strain found in animals, Zhang noted."MRSA has always been found in human patients, but we found this in retail meat, so retail meat can be a reservoir of these bugs," said Zhang."When people handle food, they can get the bugs from the meat if the meat is already contaminated," she explained.The risk of becoming infected is especially high if you have open cuts or sores on your hands or skin, Zhang added.MRSA is common in hospitals and nursing homes, where it can cause serious illness and even death.But recently "community-acquired MRSA" has become a problem among some high school and college athletes who share equipment.This type of MRSA appears as a skin infection and is usually less serious, according to CDC.MRSA is killed when the meat is cooked thoroughly, experts say.Other precaution measures include:-- Wear gloves when handling meat, especially when there are wounds on the hands;-- Washing plates or utensils used to prepare food before using them again to eat; and-- Disinfect counters that have come into contact with meats.

BEIJING, Jan. 25 (Xinhua) -- The central parity rate of yuan, the Chinese currency, Tuesday gained 2 points to 6.5881 against the U.S. dollar, according to the China Foreign Exchange Trading System.China's central bank announced in June 2010 it would further reform the exchange rate formation mechanism to improve its flexibility.On China's foreign exchange spot market, the yuan can rise or fall 0.5 percent from the central parity rate each trading day.The central parity rate of the RMB against the U.S. dollar is based on a weighted average of prices before the opening of the market each business day.

BEIJING, Jan. 19 (Xinhua) -- China's central government on Wednesday called on local authorities to step up efforts to ensure a stable market supply of daily necessities, such as food and clothing, as freezing weather continues to plague south and southwest China.The Ministry of Commerce required local government departments to guide companies to increase supplies such as rice, edible oil, meat and vegetables.It also required local departments to closely watch market changes and release reserves of commodities when necessary, said a statement on its website.The statement said the government of southwest China's Chongqing Municipality has urged local supermarkets to maintain the prices of 10 types of vegetables that are affordable to the public, while authorities in the rain and snow-battered Guizhou and Hunan provinces guided logistics companies and wholesales markets to take measures to insure supplies.The Ministry of Agriculture on Wednesday also ordered local departments to expand areas for growing vegetables when conditions allow, as agricultural experts were also sent to fields to help farmers save their crops.The country's meteorological authority forecast Wednesday that over the next three days, heavy snow and icy rain would continue in provinces and municipalities including Guizhou, Hubei, Hunan, Jiangxi, and Chongqing.

BEIJING, March 22 (Xinhuanet) -- NASA scientists are testing its next-generation Mars rover, which will land on Mars next year, under extreme conditions at space-simulation chamber in California, media reports said Tuesday.Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., say they've installed the Curiosity rover in a space-simulation chamber that can mimic the environment the probe will encounter on Mars.  After the chamber's large door was sealed last week, air was pumped out to near-vacuum pressure, liquid nitrogen in the walls dropped the temperature to minus 130 degrees Celsius, and a bank of powerful lamps simulated the intensity of sunshine on Mars.After the test period, the rover along with other portions of NASA's Mars Science Laboratory spacecraft including the cruise stage, descent stage and backshell -- part of protective covering -- will be shipped to the Kennedy Space Center for final preparation for the launch window from Nov. 25 to Dec. 18, 2011. Curiosity will study whether a selected area of Mars has offered environmental conditions favorable for microbial life and for preserving evidence about whether Martian life has existed.
