MEXICO CITY, May 18 (Xinhua) -- The Mexican government signed an agreement with the non-governmental group TRAFFIC on Tuesday to exchange information about illegal seizures of flora and fauna species in Mexico.The agreement with the wildlife trade monitoring network also called for the Mexican government to provide information on the routes used to transport such organic materials.The agreement was signed on the sideline of the 16th meeting of the Trilateral Committee for Wildlife and Ecosystem Conservation Management in the city of Oaxaca, south Mexico. Representatives of Canada, the United States and Mexico also attended the meeting.Among the list of 20,000 animals, vegetation and insects that TRAFFIC considers to be threatened by illegal trafficking worldwide, 2,500 of the organisms have their origins in Mexico. This amounts to 12 percent of the species most subject to buying, selling and transporting in the black market and threatens the survival of various ecosystems.The Mexican species that are listed among the most threatened by illegal trafficking are the cactus, orchids, reptiles, maguey plants, ferns, amphibians and fish.

LOS ANGELES, March 4 (Xinhua) -- The California Department of Public Health on Friday announced a recall of hazelnuts which might be contaminated by E. coli bacteria.The department said it ordered the recall after seven people fell sick with E. coli bacteria from eating tainted hazelnuts.The seven illnesses include one in Michigan, three in Minnesota and three in Wisconsin, said Dr. Howard Backer, interim director of the department.The hazelnuts were distributed by DeFranco & Sons, a Los Angeles company, said the department.After being notified of the contamination, the company is voluntarily recalling the nuts, the department said.The hazelnuts affected by the recall were sold under the brand names Sunripe, George Packing, Firestone Farms and Northwest Hazelnut and were distributed nationwide from Nov. 2 to Dec. 22, according to the department.The 50-pound bags of hazelnuts and mixed nuts with hazelnuts may have been repacked or sold from bulk containers, the department said, adding people who had bought the hazelnuts should not eat them.Consumers should check with retailers to determine if their nuts are subject to the recall, and if they are, should discard them, the department added.People who develop symptoms after consuming hazelnuts should seek immediate medical attention, the department suggested.E. coli may cause symptoms that include bloody diarrhea, stomach cramps and dehydration. In extreme cases, patients can suffer potentially life-threatening complication known as hemolytic uremic syndrome, which includes kidney failure.Young children and the elderly are the most vulnerable to the risk.

BEIJING, May 11 (Xinhuanet) -- New retirees suddenly confronted with plenty of time on their hands might be happy to learn that reading keeps one mentally alert and abreast of current aff airs, says Ursula Lenz of Germany's working group of senior citizens' organizations, BAGSO.Growing old can present difficulties such as failing eyesight or problems concentrating, but experts encourage the elderly not to give up on reading and to adapt to their situation.From the perspective of health professionals, there are many advantages to reading books or newspapers for senior citizens.Reading helps the elderly keep a sharp mind. The ability to transform words into mental images is good for cognitive performance. Reading also improves vocabulary, language use and the ability to concentrate, according to Simone Helck from the Kuratorium Deutsche Altershilfe, an organization in Germany that helps promote and develop strategies for taking care of the elderly.So, what exactly happens in the brain when we read?"The brain builds new synapses, junctions between the neurons, when it's stimulated such as during reading," says Manfred Gogol, a physician and president of Germany's Society for Gerontology and Geriatrics.Gogol recommends reading books that deal with subjects that are of special interest to the reader. If a long novel seems like too much work, then try a novella or collection of short stories.But a prerequisite for reading is that any sight defect is corrected by an optician.In response to the needs of elderly people, publishers print books with large typefaces and bigger line spacing. Lenz says it is worthwhile asking for large print books in libraries and bookshops.But no matter what the reading matter is, another important aspect is being able to exchange opinions about a book with other people. Whether it's a society magazine, highbrow literature or a daily newspaper, there is always something to talk about.
