Will Lettuce Recall Be a Wake-up Call?

Friday, May 21st, 2010

As nearly half the United States deals with an outbreak of a rare strain of E. coli in lettuce—which has sickened at least 30 people—consumers should start demanding better food-treatment methods and pressing Congress to expand testing.

Safer food-treatment and testing methods are needed

Safer food-treatment and testing methods are needed

Last week, there were two recalls of romaine lettuce related to the outbreak, both by distributors who bought lettuce from the same Arizona farm. Freshway Foods announced a 23-state recall of romaine lettuce last week, while Vaughn Foods of Oklahoma announced a recall May 17, the AP reports.

The romaine was not sold directly to consumers in the produce section but was used by food-service companies and supermarkets in salad bars and “grab and go” meals. Several of the victims were students at colleges in Michigan, Ohio and New York who apparently ate the infected lettuce in dining halls, according to the Washington Post.

Lettuce is supposed to be healthy, right?

Electron Beam Conference at Texas A & M University

Tuesday, May 11th, 2010

The 1st Annual Hands-on Workshop on Electron Beam and X-ray Irradiation Technologies was held April 4-8, 2010 at the National Center for Electron Beam Research on the Texas A&M University campus in College Station, Texas. The workshop was attended by 16 representatives from the government and private industry (I am pictured the 7th from the right). Participants came from the United States, Mexico and Africa. The participants included representatives from the government, academia, and private industry.  In addition to technical presentations covering the rationale for food irradiation, dosimetry, consumer acceptance and sensory and toxicological studies, there were guest speakers who discussed topics such as phytosanitary applications of irradiation, safety and control systems, and E-Beam and X-ray facility design considerations. In the afternoons, the participants had the opportunity to have hands-on experience with alanine dosimetry, irradiating and measuring dose distribution from E-Beam (single and double beam) and X-ray linear accelerators (linacs), as well as determining the D-10 value of microbial inactivation. Participants were also able to experience the spirit of Aggieland,   student life on Texas A&M University campus, and some A&M’s long standing traditions, such as yell practice and the Aggie ring.  Dr. Suresh Pillai and his workshop team (Charlotte Rambo, doctoral student and Dr. Palmy Jesudhasan, Research Scientist) did a great job hosting the event and have already started the planning for the 2nd Annual Hands-on Workshop in 2011.
