Antibiotics In Animal Feed Encourage Emergence Of Superbugs – FDA Sued By Health And Consumer Organizations

If the FDA concluded in 1977 that adding low-dose antibiotics used in human medicine to animal feed raised the risk of antibiotic-resistant bacteria, why has it still done nothing about it? A suit filed by some health and consumer organizations says the FDA has not met its legal responsibility to protect public health – the practice of routinely adding low-dose antibiotics to animal feed has to stop, and the FDA has the authority to make it so.

Peter Lehner, Natural Resources Defense Council (NRDC) executive director, said:

“More than a generation has passed since FDA first recognized the potential human health consequences of feeding large quantities of antibiotics to healthy animals.

Accumulating evidence shows that antibiotics are becoming less effective, while our grocery store meat is increasingly laden with drug-resistant bacteria. The FDA needs to put the American people first by ensuring that antibiotics continue to serve their primary purpose – saving human lives by combating disease.”

70% of all US antibiotic consumption is used up in adding low-doses to animal feed to make up for unsanitary living conditions and promote faster growth, according to NRDC. This practice has been steadily growing over the last six decades, despite the every-growing threat to humans of superbugs.

The antibiotic doses used in feed or water for turkeys, cows, pigs and chickens are too low to treat diseases – however, they are low enough for a significant number of bacteria to survive and build Read more…

Genetically modified cows produce ‘human’ milk

Scientists have created genetically modified cattle that produce human milk in a bid to make cows' milk more nutritious.

The scientists have successfully introduced human genes into 300 dairy cows to produce milk with the same properties as human breast milk.

Human milk contains high quantities of key nutrients that can help to boost the immune system of babies and reduce the risk of infections.

The scientists behind the research believe milk from herds of genetically modified cows could provide an alternative to human breast milk and formula milk for babies, which is often criticised as being an inferior substitute.

They hope genetically modified dairy products from herds of similar cows could be sold in supermarkets. The research has the backing of a major biotechnology company.

The work is likely to inflame opposition to GM foods. Critics of the technology and animal welfare groups reacted angrily to the research, questioning the safety of milk from genetically modified animals and its effect on the cattle’s health.

But Professor Ning Li, the scientist who led the research and director of the State Key Laboratories for AgroBiotechnology at the China Agricultural University insisted that the GM milk would be as safe to drink as milk from ordinary dairy cows.

He said: “The milk tastes stronger than normal milk.

“We aim to commercialize some research in this area in coming three years. For the “human-like milk”, 10 years or maybe more time Read more…

North Korea confirms large-scale foot-and-mouth disease outbreak

PYONGYANG: North Korean state media on Friday acknowledged for the first time that foot-and-mouth disease has broken out in the Asian country, affecting eight provinces.

Rumors had been circling for several weeks that foot-and-mouth disease had broken out in the Communist country. On Thursday, the state-run Korean Central News Agency (KCNA) confirmed that the disease broke out in Pyongyang at the end of 2010 and since spread to eight other provinces.

KCNA said the most seriously affected areas are Pyongyang, North Hwanghae Province and Kangwon Province. Other areas which have been affected are North and South Phyongan Provinces and Jagang Province, although the other three affected provinces were not identified.

“Type O Foot-and-mouth diseases broke out on cooperative farms, diary farms and pig farms in those areas, doing harm to domestic animals,” KCNA said. “More than 10 000 heads of draught oxen, milch cows and pigs have so far been infected with the diseases and thousands of them died.”

The state broadcaster said a national emergency veterinary and anti-epizootic committee has since been established. “An emergency anti-epidemic campaign was Read more…
