August 27 was a day of education, exploration and enlightenment for the 55 students and staff who participated in the annual New Student Industry Tour, hosted by Penn State’s Department of Dairy and Animal Science and Department of Poultry Science.

Now in its 11^th year, the tour offers incoming freshman and other students new to the campus, a unique educational opportunity to view the diversity of Pennsylvania agriculture, from the traditional to the exotic.  It has been a big “hit” since we launched the tour.

I had a wonderful (and sweltering) time at Ag Progress Days (APD) last week.  This is an event sponsored by the College of Agricultural Sciences and attracted about 50,000 attendees over three days.

I have been asked:  what do you do out there for three days?  A lot (more about this later)!  And, the faculty and staff in the Department of Dairy and Animal Science do a great deal to put on a variety of educational and science-based programs for APD attendees. Read the rest of this entry »

A ProMED-mail post (August 2, 2009)

Hong Kong’s health authorities announced Wednesday [27 Jul 2009] that a new variant of the H3N2 seasonal influenza virus has been found in the city. The Brisbane strain has been the prevalent circulator of H3N2 in the past year, and the new variant is its direct descendent, said Thomas Tsang, controller of Hong Kong’s Center for Health Protection (CHP). “However, it has some genetic changes distinguishing it from the old Brisbane strain,” he said. He said it is normal for viruses to go through changes, adding that overseas health authorities, including those in Canada, Britain and Australia, had also found the new variant.

There is an ongoing overweight/obesity epidemic in the United States.  Estimates from the National Center for Health Statistics are that about 66% of Americans are either overweight of obese! This epidemic not only poses a health problem for overweight/obese individuals, but also represents a rapidly expanding burden on health care costs in America. Read the rest of this entry »

A recent outbreak of equine Herpes Virus 1 (EHV-1) in Southwest Pennsylvania has prompted many questions and concerns from horse owners. The farm has been quarantined to prevent the spread of the virus.  While there is no immediate threat outside that farm, horse owners should be vigilant and practice high levels of biosecurity.  Commonly known as Rhinopneumonitis or “Rhino,”  Equine Herpes Virus (EHV) has many different types and is best known by horse owners to cause respiratory disease and abortions.  It is important to know that EHV can cause other disease states in horses.  EHV-1 found in Southwest Pennsylvania was the cause of a neurologic form of the disease.

On June 9, 2009, I posted a blog “The Slippery Slope Involved in the Proposed Move of the U.S. Foot and Mouth Disease Lab – What a “Mess!” that questioned the basis for the Department of Homeland Security (DHS) support for the movement of FMD virus and research from the current location at Plum Island Animal Disease Research Center (PIADC) to the newly announced National Bio and Agro-Defense Facility (NBAF) site managed by Kansas State University.  This morning’s Washington Post had a very interesting article that discusses concerns about this issue.  Enjoy reading the story.

The Department of Homeland Security relied on a rushed, flawed study to justify its decision to locate a $700 million research facility for highly infectious pathogens in a tornado-prone section of Kansas, according to a government report. Read the rest of this entry »

Two Canadian Food Inspection Agency [CFIA] inspectors appear to have contracted swine flu while investigating an outbreak of the new virus in pigs on an Alberta farm in late April [2009], the agency confirmed on 21 July 2009.

The cases appear to be the first report of people catching the new H1N1 virus from pigs. Read the rest of this entry »

Whether speaking of a 58-year-old man or a 38-year-old woman, or a little boy of 9, officials announcing swine flu deaths are almost always quick to note “underlying health  conditions” may have contributed to the fatal outcome. Asthma, heart disease, diabetes, maybe even obesity are among the conditions used to help explain why swine flu infection is hospitalizing and killing younger people, people who would be expected to make a full recovery from seasonal flu.

Background: Common to all fields of science and engaged scientists is their willingness to participate in the free exchange of ideas. This blog often posts such ideas in the form of existing citable scientific contributions and news items. In recent conversations among like-minded individuals regarding contemporary topics in livestock production agriculture and biotechnology, the issue of U.S. animal disease research was raised. No factor in livestock production can impact production efficiency and profitability more than a disease issue. And, in the case of a highly contagious foreign animal disease (FAD) where the U.S. would change from disease-free status to one of a FAD positive diagnosis, livestock production could be decimated in quick order.

A ProMED-mail post (May 28, 2009)

The following is [1] a statement of the research program of the United States Department of Agriculture (USDA) Agricultural Research Service (ARS), and [2] the outcome of a study of the cross-reactivity of serum samples from US pigs against the new swine origin 2009 H1N1 influenza virus (S/O H1N1). The results of this analysis indicate that pre-existing immunity induced by swine influenza viruses circulating in the US may not protect pigs against the new S/O H1N1 influenza virus presently circulating in people.
