Food Industry Safety Checks Under Fire
A House Energy and Commerce Investigations subcommittee released new pictures and documents it says show the food industry's self-policing policies failed to catch unsanitary conditions at the peanut processing plant responsible for a nationwide salmonella outbreak. The incident sickened almost 700 people and is being blamed for at least nine deaths, the Associated Press reported Thursday.
Dozens of companies that bought peanut paste and other ingredients from Peanut Corp., which is under criminal investigation in connection with the outbreak, failed to pick up the problems because they relied on safety audits by inspectors hired by Peanut Corp. "There is an obvious and inherent conflict of interest when an auditor works for the same supplier it is evaluating," said Rep. Bart Stupak (D-Mich.), chairman of the subcommittee, calling it a "cozy relationship," the AP reported.
Thursday's hearing was held as calls for major changes in the U.S. food safety system grew louder, from consumer groups, politicians, and even the head of Kellogg Co. He called for an overhaul of policing policies after the cereal maker lost $70 million in the salmonella outbreak when it had to recall millions of products, the AP reported. David Mackay, Kellogg's chief executive, said companies should be required to have written safety plans and submit to annual inspections.
Last week, President Barack Obama launched a special review of food safety programs, and lawmakers have introduced legislation to take safety oversight away from the U.S. Food and Drug Administration and create a new agency with stronger powers and more funding, the AP reported.
Study Offers Clues to Epilepsy in Some Alzheimer's Patients
Tests in mice show why about a third of Alzheimer's patients develop epilepsy, say researchers at the University of Aberdeen in Scotland.
They found that Alzheimer's-related amyloid clumps that form in the brain increase the sensitivity of nerve cells, making them prone to seizures, BBC News reported.
The study was published in the Journal of Neuroscience.
If the same thing is found in humans, some Alzheimer's patients will need different types of drugs. Currently, a class of drugs called cholinesterase inhibitors are widely used to treat Alzheimer's patients, BBC News reported.
The drugs halt the breakdown of acetylcholine, a neurotransmitter associated with memory. However, these drugs also increase the risk of seizure. To complicate matters, drugs that control seizures can worsen Alzheimer's symptoms.
New drugs that can treat both problems need to be developed, said researcher Professor Tibor Harkany, BBC News reported.
FDA Panel Backs Heart Drug Multaq
The drug Multaq should be approved for sale in the United States to treat the common heart rhythm disorder atrial fibrillation, a Food and Drug Administration advisory panel recommended Wednesday.
In 2006, the FDA rejected Multaq due to a study that found the drug increased the risk of death and cardiovascular problems. Drug maker Sanofi-Aventis SA was told to conduct an additional study, The Wall Street Journal reported.
