Washing fresh produce may not be enough to make contaminated food safe, according to a report on KTVU.com about USDA findings. KTVU is the Bay Area Fox Television affiliate.
USDA found that irradiation could provide a reliable way to reduce the number of foodborne illnesses reported each year in the United States, according to the director of the study.
For the story, the TV station sought comment from UC Davis Cooperative Extension specialist Christine Bruhn. Bruhn said some activists are opposed to irradiation, but the process is gaining consumer acceptance as studies have shown that it is effective at reducing pathogens that cause illness, according to the version posted on the Web.
An article in the Los Angeles Times gardening section today takes on weeds -- especially those that were deliberately introduced by nurseries for landscaping purposes but have naturalized, spread wildly and are crowding out native species that provide wildlife habitat.
Freelance writer Emily Green centered her story on the UC ANR publication "Weeds of California and Other Western States" by UC Davis Cooperative Extension weed specialist Joseph M. DiTomaso. In an interview with Green, DiTomaso said pampas grass is a perfect example of a landscape plant gone wild.
Pampas grass was introduced by a Santa Barbara nursery in 1848, according to the article. When commercial production began in 1874, the plants were propagated by dividing them at the root, and only females were selected for their superior plumes.
"To simplify the process, they turned to seeds and planted the seeds and sold plants as tufts before they flowered, so they did not know if they were males or females," DiTomaso was quoted. "Males got out in the environment and boom, within about 15 years, the plant became an invasive problem. We actually had the solution, but we didn't stick with it."
Other common landscape plants that have turned into difficult weeds are salt cedar, arundo, English and Algerian ivy, ice plant, periwinkle and nasturtiums.
To address the problem, the article says a diversity of groups -- including Sustainable Conservation, the UC Davis Arboretum, Nature Conservancy, California Farm Bureau, California Native Plant Society, Huntington Botanical Gardens, California Department of Food and Agriculture and California Assn. of Nurseries and Garden Centers -- worked together to form an organization called PlantRight, www.plantright.org. It doesn't mention UCCE.
PlantRight has started its effort by enlisting UCCE's Master Gardeners to find landscape plants the group has identified as weeds in local nurseries. The group will then ask nurseries to take the offending plants off their shelves, the story said.
An interesting side note: In her article, Green officially christens the word "invasive" a noun.
UC Cooperative Extension 4-H and environmental horticulture advisor Rose Hayden-Smith provided information about California school gardens to an Associated Press writer who was reporting on the growing popularity of school gardens in the United States.
The story focused on a concrete schoolyard in hurricane-recovering New Orleans that has been transformed into a garden. It appears that writer Janet McConnaughy was looking for national numbers on school gardens, but noted that difinitive data are scarce. She wrote that the National Gardening Association's online registry lists 1,500 school gardens, up from 1,100 a year ago, and she spoke to Hayden-Smith for information on California's school gardens.
Hayden-Smith told the reporter that California alone had about 1,000 instructional school gardens in 1995 and triple that number by 2000. Nearly 3,850 schools - more than 40 percent of all state schools - got state grants last year to begin or improve gardens, according to the article.
KPIX in San Francisco noted that UC Davis entomologist James Carey told a San Francisco Board of Supervisors committee that the decision by the California Department of Food and Agriculture to conduct aerial spraying for the light brown apple moth is "scientifically misguided" and that there are "other tools" that can be used to control the agricultural pest.
Like paparazzi chasing a celebrity, Bay Area media have vigilantly followed the whereabouts and goings-on of California's newest exotic pest, the light brown apple moth. ANR scientists continue to be a valuable source of information.
Today, the Berkeley Daily Planet quoted UC Berkeley entomology professor Miguel Altieri. According to the article, Altiere said CDFA's plan to eradicate the light brown apple moth “is like the 9-11 terrorist policy applied to agriculture."
On Monday, the San Francisco Chronicle ran a story about health problems associated with moth pheromone treatments designed to eradicate LBAM.
Reporter Jane Kay interviewed Ron Tjeerdema, a UC Davis toxicology professor and a member of the state agricultural department's task force on the aerial spraying. According to the article, he said he reviewed the list of ingredients and didn't find anything of particular concern, adding that the ingredients are found in other products.
But Megan Schwarzman, a research scientist in UC Berkeley's School of Public Health, cautioned that just because the chemicals are found in other products "doesn't indicate their toxicity or their safety," Kay's story says.
For all the latest scientific information on LBAM, read the current issue of California Agriculture journal. The cover story will tell you "everything you always wanted to know about LBAM but were afraid to ask," according to managing editor Janet Byron. Byron wrote a news release, being distributed to the media today, that gives a synopsis of the article's content.
