It's a Mad, Mad, Mad (Cow) World
Despite actions taken by the federal government to
prevent the spread of mad cow disease (bovine spongiform encephalopathy) to the
United States, there is no guarantee there will be rapid detection of the
disease if it crosses the nation's borders. According to a new report by the
General Accounting Office, "Federal actions do not sufficiently ensure that all
BSE infected animals or products are kept out or if BSE were found, it would be
detected promptly and not spread to other cattle through animal feed or enter
the human food supply." Beef infected with mad cow disease is believed by
scientists to be linked to Creutzfeldt-Jacob Disease, which is responsible for
the deaths of over 100 humans.
Beavers a Dam Nuisance
U.S. Forest Service staffers say Montana flat-tail
beavers that roam free on Lake Tahoe's south shore aren't spending as much time
building dams as they are eating. The problem is they are gnawing away at
aspens, cottonwood and willows, causing soil erosion on the riverbank.Some
residents would like to eradicate the beaver population, but the Forest Service
has only tried to relocate the little varmints.
Hunters Don't Want to Free Willy
Dr. Seiji Ohsynu, director general of the Japanese
Institute of Cetacean Research, announced that Japan plans to expand its
whaling program to include the killing of 50 endangered sei whales, 100 minke
whales, 50 Bryde's whales, and 10 sperm whales. Although the announcement was
met with outrage, Japan justifies its whaling policies under a research
provision of the regulations of the International Whaling Commission. Japanese
fishery officials say they need to kill whales in order to study breeding and
feeding habits.
Don't Cry For Me, Argentine Ants
A severe decline in coastal horned lizards in
Southern California may be due to the proliferation of Argentine ants, the
little pests that invade homes during heavy rainfall. According to two
scientific papers published last February, the Argentine variety has become so
prolific they have displaced many of the larger native ants traditionally eaten
by lizards. Scientists at U.C. San Diego found that the finicky lizards don't
seem to like the taste of the foreign ants and lost weight unless they were fed
their usual fare.
Something Fishy About Mercury Levels
The Environmental Working Group (EWG) has obtained
internal documents showing focus group meetings organized by the Food and Drug
Administration supported stronger consumer warnings regarding mercury in fish
than those actually issued by the agency. The FDA stated in 2001 that pregnant
women and women of childbearing age should avoid eating fish with the highest
levels of methyl mercury, including shark, swordfish, king mackerel, and tile
fish. According to the EWG, the FDA has been remiss in not letting the public
know the whole truth about mercury poisoning, and says that that tuna should be
added to the list. The FDA stands by its current consumer advisory, but says
that it will convene a meeting later this spring to review issues surrounding
methyl mercury in commercial seafood.
