The owner of one farm at the center of a massive egg recall apologized to anyone who may have been sickened by his product Wednesday, while another refused to answer questions about conditions at his operation.

Orland Bethel, president of Hillandale Farms of Iowa, invoked his Fifth Amendment right against self-incrimination when asked whether he knew about unsanitary conditions at one of his farms before an August e-mail from a production manager.Bethel was appearing before a House subcommittee investigating the outbreak of Salmonella enteritidis that sickened more than 1,600 people and triggered the recall of more than half a billion eggs.

Abbott Laboratories said Wednesday that it has issued a recall of approximately 5 million cans of certain Similac-brand powdered infant formula due to the possibility of the presence of a beetle.Abbott spokeswoman Melissa Brotz said that the presence of a small common beetle was detected in the product produced at a manufacturing facility in Sturgis, Michigan.The company has since stopped production and shipment of the affected formula and contacted the Food and Drug Administration to initiate the recall.The recall includes certain Similac powder product lines that come in 8-ounce, 12.4-ounce, and 12.9-ounce cans.

A new study released Thursday suggests mammograms might not be as effective in reducing deaths from breast cancer in women over 50 as previously thought.The study, published in the New England Journal of Medicine, analyzed data from more than 40,000 women with breast cancer.It concluded the availability of mammography screening corresponded with a reduction in the rate of death from breast cancer, "but the screening itself accounted for only about a third of the total reduction."Researchers from Norway and Harvard University compared the death rates from breast cancer in four groups: one group of women from 1996 through 2005 who were living in Norwegian counties with screening; another group in the same time period who were living in counties without screening; and two similar groups from 1986 through 1995.
