Food Safety and Swine Flu - Update #1

April 27, 2009

A deadly outbreak of "swine flu" may have killed as many as 149 victims in Mexico so far, and sickened hundreds more. Twenty-six of the Mexican deaths have been confirmed as swine flu victims.

Confirmed cases of swine flu – none of them life-threatening – have been reported in the United States (40), Canada (6) and Spain (1). Health agencies in several more countries – including Australia, BrazilFranceIsraelNew Zealand, Sweden and Switzerland – are investigating suspect cases.

The World Health Organization has declared a "Level 4" pandemic alert, indicating that the likelihood of a pandemic has increased, but that a pandemic is not inevitable. Governments around the world have issued travel advisories, and many countries have instituted airport screening of passengers arriving from Mexico. Schools in Mexico and all 14 schools in one Texas district have been closed and many public events in Mexico cancelled.


What is swine flu and how is it spread?

Live pigs can become infected with an influenza virus, just as humans can. The form of the virus that typically infects pigs – swine flu – occasionally is passed from infected pigs to humans. As with other influenza viruses, individuals become infected by breathing contaminated air – not by eating contaminated meat.

The virus that is behind the present outbreak is not a pure-bred swine flu virus. It is a hybrid virus that contains portions of swine, bird and human influenza viruses. Health professionals are still in the dark as to how easily this particular virus can be transmitted from person to person, how dangerous it is, and how much protection the current influenza vaccine provides. Fortunately, the virus appears to be sensitive to anti-viral drugs such as Tamiflu.

While monitoring airline passengers who arrive from Mexico and other countries that have confirmed cases of swine flu is a sensible precaution, and placing an embargo on the importation of live pigs from affected countries is understandable, some countries have gone overboard in their efforts to prevent the disease from crossing their borders. 

Since swine flu is not transmitted by eating contaminated pork meat, why have Russia and China embargoed the importation of pork meat from Mexico and the United States? According to Tom Johnston, reporting in Meatingplace.com, Thailand, Jordan, Indonesia and the Philippines have taken similar steps. Ukraine has gone even farther, adding Canada and New Zealand to its embargo list, even though New Zealand has yet to confirm a single case of swine flu.  There is no scientific basis for these embargoes.

It's understandable when individuals who are not schooled in medicine or microbiology make panic-based decisions. It's unconscionable for national health authorities to do so. 

Swine flu is not a food-borne disease.

  1. Hi Phyllis, Thanks 4 the info. I'm going to check my stash of tamiflu. I'm thinking I'll hold up at home & not let anyone who is exposed to kids in til this is over. I'm thinking of canceling my hispanic cleaning lady tomorrow bcs her kids could have exposed her. Am I overreacting? Puppy love from Joy & furry folk

    You might want to contact the information line given in the status report.

    Given your health situation, isolation isn't a bad idea. Make sure that your tamiflu has not reached its expiry date.

  3. Thanks Phyliss! It will be good to get non media hyped information :) This is killing the travel business. Daughter has people she has booked for Mexico in July calling and wondering if they should cancel. Industry friend of hers had a group of 20 for June call and cancel yesterday :( How do I get on the list for up-dates from you? Anita
