BEIJING, Nov. 24 (Xinhua) -- In response to public suspicion stoked by recent dumpling contamination scandals, China's Ministry of Health on Thursday said the new food safety standard for flash-frozen dumplings did not show signs of leniency.The Ministry introduced the new food safety standard on flash-frozen dough or rice products on Thursday.The Ministry has been accused of loosening scrutiny over a disease-generating bacteria in such foods, staphylococcus aureus, or golden staph, which can cause various diseases, including pneumonia and sepsis, and is sometimes life-threatening.The controversy became particularly relevant after several major brands of frozen dumplings have been successively recalled in recent months.In October, a Henan-based company, Zhengzhou Sinian Food Co., Ltd, confirmed the contamination of golden staph in its flash-frozen seafood- and pork-stuffed dumplings.Frozen dumplings made by Hong Kong-based manufacturer Wanchai Ferry were found to contain golden staph in November, and some of its products have been pulled from shelves.The previous standard provided that no golden staph should be tested in such food, while the new one gives a quantitative restriction that the volume of the bacteria should be no more than ten to the fourth degree.Liu Xiumei, a food safety expert with the Chinese Center for Disease Control and Prevention, said at the press conference held by the health ministry that such bacteria becomes inactivate after the food is boiled for a few seconds, and it takes a volume of ten to the fifth degree to generate toxicity.The previous standard could only serve as a general provision due to the lack of quantitative microbiological testing back when it was introduced, Liu said, stressing that the new standard is not a sign that the Ministry has gone soft on bacterial contamination of relevant foods.The new standard will come into effect starting Dec. 21, 2011.

BEIJING, Oct. 13 (Xinhuanet) -- Scientists have decoded the genome of Black Death which caused one of the worst plagues in human history.The finding was published Wednesday in the scientific journal Nature.A team of German, Canadian and American scientists collected the bacteria's DNA from ancient plague victims' teeth and bones, which were excavated from the burial ground in London.With a careful NDA comparison between the ancient bacteria and the modern strains, scientists found the direct variant of the medieval bacteria still exist today.Black Death's descendants kill around 2,000 people a year, mostly in the developing world, the scientist said."This will provide us with direct insights into the evolution of human pathogens and historical pandemics," said Johannes Krause Of Germany's University of Tubingen, who worked on the study.Black Death, the fatal plague of medieval Europe, wiped out some 30 million people -- about 50 percent of the population on the continent, within just five years, between 1347 and 1351.

BEIJING, Jan. 6 (Xinhua) -- Surveillance data on the size and frequency of earthquakes in Antarctica collected by China's Great Wall Station show that the continent is not earthquake-free, a Chinese seismic expert said Thursday."China's newly-built seismic observatory in Great Wall Station has documented a hundred-odd earthquakes occurring in the region over the past year," said Chang Lijun, a member of China's 28th Antarctic expedition team.The discovery challenges the prevailing notion that the Antarctic has no earthquakes, as many earthquakes have gone undetected due to lack of seismological observation in the region.However, thanks to technological advances, scientists have discovered that the continent is still subject to some minor tremors.Chang, also an associate researcher at China Earthquake Administration's Geophysics Institute, said last year's earthquakes ranged in magnitude from 0.5 to 4, scales which are usually undetectable to common people.The tectonic movements of Antarctica, which sits on two plates that pulled away from each other in the northern Ross Sea between 28 and 40 million years ago, but later converged, fascinate geologists worldwide.At the end of 2010, Chinese scientists set up a new broadband seismic observatory in Great Wall Station, greatly increasing China's ability to measure tremors and tectonic movements on the continent.

CAPE TOWN, Dec. 15 (Xinhua) -- More people voluntarily get HIV tests in the Western Cape province, an indication of people's rising awareness of the epidemic, authorities said on Thursday.Nearly 11,000 people in the province have been tested over the past 10 days as authorities stepped efforts to halve the number of HIV transmissions over the next few years, according to official figures.Authorities expect more people to be tested when the monthly campaign ends by the end of December.In December last year, 67,111 people were tested.This year's figure is expected to be higher than that of last year, said Western Cape Premier Helen Zille.The campaign, known as Know Your Status and Win, may become a regular feature in the province, said Zille.To encourage more people to take part in the campaign, the province offers awards to several winners by drawing, ranging from 10,000 rand (about 1,250 U. S. dollars) to 50,000 rand (about 6, 250 dollars)."The bottom line is that people respond to incentives," said Zille, who hailed the campaign a success.She said the reality was that those who stubbornly did not want to get tested, were those crucially in need of doing so.While the data still had to be audited, preliminary results indicated a spike in the number of people who were tested.There was also a significant increase at routine testing center that were not part of the campaign, said Zille. Of 22.9 million HIV positive people in sub-Saharan Africa, 5.6 million in South Africa, according to an annual report by UNAIDS.
