E. Coli Found in Nestlé Cookie Dough: FDA

A sample of Toll House refrigerated cookie dough made at a Nestlé USA plant in Virginia has tested positive for E. coli bacteria, the U.S. Food and Drug Administration said Monday.

The agency is waiting for test results to determine if the E. coli in the cookie dough from the plant in Danville is the same strain that sickened at least 69 people nationwide, the Wall Street Journal reported. The tests are expected to be completed later this week.

The E. coli was found in a sample from a 16-oz. chocolate chip cookie dough bar that had a production date of Feb. 10 and best-use date of June 10. The sample was collected when FDA investigators were inspecting the Danville plant.

"Nestlé continues to work closely and in full cooperation with the FDA on the ongoing investigation," said Laurie MacDonald, vice president of corporate and brand affairs at Nestlé USA, the Journal reported. "We are very concerned about those who have become ill from E. coli 0157:H7, and deeply regret that this has occurred."

Daily Sex Improves Sperm Quality: Study

Having more sex helps men with fertility problems boost the quality of their sperm, says an Australian study that included 118 men with damaged sperm.

When the men had sex every day for a week, 81 percent of them had a 12 percent reduction in the amount of sperm with damaged DNA, the Associated Press reported.

The study was presented at a meeting of the European Society of Human Reproduction and Embryology.

Experts note that if sperm is in the body for too long, it's more likely to get damaged, the AP reported.

Other ways of improving sperm quality include not smoking, drinking in moderation, exercise, and consuming more antioxidants.

Too Few Young Adults Treated for Alcohol, Drug Problems: Study

More than one in five young adults in the United States (7 million) need treatment for alcohol or illicit drug use, but only 7 percent of them receive treatment at a specialty facility, says a federal government study released Monday.

Those levels have remained relatively stable since 2002, said the Substance Abuse and Mental Health Services Administration (SAMHSA) study of 2007 data from a national survey of 22,187 adults ages 18 to 25.

"Substance use disorders are preventable and treatable yet we continue as a nation to allow the lives of 1 in 5 young people and their families be torn apart by substance abuse," SAMHSA Acting Adminstrator Eric Broderick said in a news release. "As a nation we must redouble our efforts to prevent substance abuse in the first place and ensure treatment is available to those in need."

The study also found that 96 percent of young adults who needed, but didn't receive, treatment for substance-use problems didn't believe they needed help.

Among the other findings from the 2007 data:

• Among young adults, 17.2 percent needed treatment for alcohol disorders in the past year, 8.4 percent for illicit drug disorders, and 4.4 percent for both alcohol and illicit drug disorders.
• Young adults covered by Medicaid/Children's Health Insurance Program (CHIP) were more than three times as likely as those with private insurance to receive treatment for alcohol or illicit drug use in a specialty facility -- 13.2 percent vs. 4 percent.

Studies Detail New Ovary Preservation, Transplant Methods

New methods of preserving and transplanting ovaries could improve older women's chances of having children, two new studies suggest.

A growing number of women are delaying having a family until they're in their 30s or 40s, when they're more likely to have fertility problems. But doctors say it may be possible to have an ovary removed and frozen when a woman is in her 20s or 30s and have it reimplanted when she's ready to have children, the Associated Press reported.
