Ground Beef Recalled Over Salmonella Concerns
A California-based beef packing plant has recalled 825,769 pounds of ground beef products that may be contaminated with an antibiotic-resistant form of Salmonella and may be linked to an outbreak of illness in Colorado, the U.S. Department of Agriculture announced Thursday.
The ground beef recalled by Fresno-based Beef Packers, Inc., was sent to Colorado, Arizona and Utah, and sold in California, Dow Jones News reported.
The USDA said the Newport strain of Salmonella that may be in the ground beef "is resistant to many commonly prescribed drugs, which can increase the risk of hospitalization or possible treatment failure in infected individuals."
The agency also noted that the "most common manifestations of salmonellosis are diarrhea, abdominal cramps, and fever within eight to 72 hours," Dow Jones reported.
Seasonal Flu Vaccines Shipped Early
Concerns about the swine flu pandemic have led vaccine makers to start shipping seasonal flu vaccines to the U.S. market much earlier than normal.
GlaxoSmithKline PLC and Novartis AG both started shipping seasonal flu vaccines Wednesday, while Sanofi Pasteur started on July 27, the Associated Press reported.
Novartis is "weeks ahead of schedule," Sanofi is about two weeks early, and Glaxo is slightly ahead of its usual mid-August start.
The companies said they expect concerns about swine flu will lead to increased demand of seasonal flu vaccines this year. They also want to complete production of seasonal vaccines to ensure capacity to make swine flu vaccine, the AP reported.
Meanwhile, the World Health Organization said Thursday that vaccine manufacturers are on track to start delivering the first batches of swine flu vaccine in September.
According to AP, WHO vaccine director Marie-Paule Kieny said several drugmakers have started testing the vaccine in humans and early safety results should be available next month. Those will clear the way for the vaccine's use.
Clinton-Brokered Deal to Bring Low-Cost HIV Meds to Poorer Nations
Former President Bill Clinton has helped forge a deal whereby two drug companies will allow poor countries to gain cheaper access to HIV medications, the Associated Press reported.
The agreement, which involves powerful antiretroviral medications made by Pfizer Inc., and Mylan Inc., should lower the cost of key drug regimens to less than $500 per year, Clinton said in New York City on Thursday.
The drugs involved in the deal will be used by people who may have already developed resistance to other medications.
Since 2002, the nonprofit Clinton Foundation has brokered a number of cost-cutting deals aimed at getting HIV-suppressing medicines to people in the developing world, the AP said.
