From Ottawa - The Canadian Food Inspection Agency- Canada's food watchdog- is warning about the risk of Salmonella from a popular brand of salami. It and manufacturer Santa Maria Foods are warning the public that Mastro brand Casalingo Salami may be contaminated with Salmonella- a bacteria that can cause high fever, severe headache, vomiting, nausea, abdominal pain and diarrhea.
From Seattle - Stem cells may one day be able to repair heart attacks. Research in rats showed that human stem cells could both differentiate into heart cells, and remain viable. The size of the grafts were up to 10% of the heart's size. The researchers hope to try the technique on humans within 3 years.
From Maryland - the FDA is recommending better labelling of sunscreens. While sunscreens have provided information about protection against UVB rays- the rays that cause sunburn- they have not typically mentioned how they protect against UVA rays. UVA rays penetrate the skin more deeply than UVB and cause tanning, wrinkles and may raise the risk for skin cancer.
And finally from California - Fish oil may be good for those with the nerve disorder- multiple sclerosis. Researchers gave 10 MS patients nearly 10 grams of fish oil per day to see if it affected their immune systems. A nearly 60% reduction in MMP-9- a marker of immune activity was noted. Further research should be done to better understand if there are long terms benefits.
