New research confirms the common house fly spreads serious hog diseases. Is Manitoba's factory hog industry dragging its heels?

Image
by Larry Powell The house fly. Photo by  USDA A veterinarian at the Walcott Veterinary Clinic in Iowa, Grant Allison, captured flies at swine operations which had tested positive for both diseases in Iowa and Minnesota. In his words, "Flies replicate in moist conditions that could involve manure. So there's an intimate relationship between manure and viruses and flies. The idea that flies might be a possible vector was immediately obvious. We came up with a plan and started by finding an outbreak and trapping flies to see if the flies were positive." They were. Not only were they carrying live viruses for both diseases, they were spreading them to healthy pigs and making them sick. What's more, the flies were even found to be infectious in January, usually considered the off-season for such harmful vectors. Dr. Allison recommends putting a larvicide in the hog feed as one tool in a program to achieve effective fly-control. He believes an extensive progra

More bad news for the world’s oceans - out of Canada!

Image
by Larry Powell Pacific oysters - with salt and lime.  By Guido - Flickr . A team of Canadian researchers has found that BC’s premier oyster-growing region off the east coast of Vancouver Island, is “highly contaminated” with micro plastics. The team, from Simon Fraser University, says it is now important to find out if the oysters themselves are ingesting the plastics. If they are, it could have implications for the health and quality of the product itself, Canada’s oyster-farmers, in general and the entire industry, worldwide. The scientists found micro-plastics at all 16 sites sampled within Lambert Channel and Baynes Sound, indicating "widespread contamination of these regions with these particles." That is Canada's prime growing area for the Pacific oyster ( Crassostrea gigas ). It is also feared the microplastics could accumulate trace metals which, in turn, could harm the oysters and other organisms on the sea-bottom.  Dynabeads, a mag

Link between river outflow and coastal sea level

Image
Woods Hole Oceanographic Institution Sea levels in coastal areas can be affected by a number of factors: tides, winds, waves, and even barometric pressure all play a role in the ebb and flow of the ocean. For the first time, however, a new study has shown that river outflow could play a role in sea level change as well. More here. Vietnam's Mekong Delta.

More help from the public trough for the corporate hog sector

by Larry Powell Manitoba’s hog industry is delighted with the latest infusion of money into swine research. Ottawa has just announced that another $18.5 million will be spent over 5 years to look into the nutrition, health and care of the nation’s swine herds, along with their "environmental sustainability" and the quality of the pork. Canadian taxpayers will pay almost $13 million of that amount, the rest from industry. This is in addition to more than $30 million already spent over the past decade (by both industry and taxpayers) for other so-called “agri-science” research. The group representing pig producers and processors,  Manitoba Pork ,  hails the announcement as “Great news!” It  says the research will be “industry-led,” and will “bring together experts in the public and private sectors to help increase the competitiveness of the Canadian pork sector.”  (Conveniently, the industry statement makes no mention of the apparent provision in the federal
