() - Almost half of the meat and poultry sold in supermarkets and grocery stores USA contains the type of bacteria that are potentially dangerous to humans, new research evaluation. Researchers tested 136 packages of chicken, turkey, pork, beef and land purchased for 26 grocery stores in five cities across the country, and found that 47 percent contained staphylococcus aureus (Staphylococcus aureus), a common cause of infection in humans. Moreover, about half of the contaminated samples contained strains of bacteria that were strattera 25mg resistant, at least three antibiotics such as penicillin and tetracycline. Some strains were resistant to the half-dozen or more. Despite high levels of pollution may sound alarming, these bacteria represent a threat to people is still unclear. We know that almost half of our meat and poultry food contaminated with Staphylococcus aureus, and more than half of them were multidrug-resistant, says Lance B. Price, Ph.D., lead author of the study, which was published Friday in the journal Clinical Infectious Diseases. What we do not know [it], as often these transfer to people. We need more research to quantify the impact on public health. Staphylococcus aureus strains and, in particular, can cause serious infections and even deaths. However, simple precautions, including cooking meat thoroughly wash hands after handling meat, and keep raw meat separate from other foods to prevent cross-contamination is believed to neutralize the risk of infection, according to Experts not involved in the study. Numerous studies of this type is done in other countries ... usually come with the same results that multidrug-resistant Staphylococcus aureus are present in various animal meat, said Pascal James Imperato, MD, Dean of the Faculty of Public Health of New York - Downstate Medical Center in Brooklyn. But still no one could make the connection between the presence of these bacteria in meat and human diseases. Multidrug-resistant strains of bacteria always care about people, said M. Gabriela Bowden, Ph.D., associate professor and expert bacteria AM Texas Health Science Center at Houston. But if you follow the rules of hygiene, you will follow the salmonella and E. coli should not be a problem. Meat that is sold in 80 different brands were purchased in Los Angeles, Chicago, Washington, DC, Fort Lauderdale and Flagstaff, Arizona and diversity of strains of Staphylococcus aureus found in the samples suggests that cattle themselves - rather than , contamination during processing and packaging - are a source of bacteria, the study noted. Each year, farmers and herders to give millions of pounds of antibiotics for animals, most of them healthy, to make them grow faster and prevent - not treat - diseases, says Price, Director of Food Microbiology and Ecology in Health Translational Genomics Research Institute, non-profit organization in Flagstaff. The combination of bacteria, antibiotics and livestock living in close proximity creates an ideal environment for bacteria to thrive and mutations that may explain the high levels of drug-resistant staphylococcus aureus seen in the study, he adds. Virtually all (96 percent) from Staphylococcus aureus strain and Price and his colleagues have developed resistance isolated for at least one antibiotic. Strains resistant to three or more antibiotics were found in 79 percent of Turkey, 64 percent pork, 35 percent beef and 26 percent of chicken samples. These four different meat from four different animals in different geographic areas, Bowden says. [S. gold] may be more common than we think. Methicillin-resistant Staphylococcus aureus (MRSA), which was especially a threat to people in hospitals and communities, was found in one package each of beef, turkey and pork, but not chicken. This sample was not large enough to arrive at an accurate assessment of prevalence in meat throughout the country, according to a study. Centers for Disease Control and Prevention, Food and Drug Administration and U.S. Department of Agriculture is currently monitoring the supply of meat from the presence of four major types of antibiotic-resistant bacteria (including salmonella and E. coli). The results show that S.aureus, should be examined regularly, so, say researchers. Copyright.
