Reduce Your Risk of Foodborne Illness
Here’s what you need to know about foodborne illnesses in just a few bites.
Beyond Salmonella: Emerging Foodborne Threats
Walkerton, a serene town in Bruce County, Ontario, with a population of under 5,000, embodies tranquil rural charm, where close-knit communities thrive amid picturesque landscapes. Here on May 15, 2000, the local public utilities commission took a routine sample of the water supply and discovered E. coli contamination. The commission didn’t notify public health officials.
In the following days, several people fell ill with bloody diarrhea. The local public utilities commission reassured officials a couple of times that the water supply was safe, even though cases kept rising. By the time health officials finally warned the community against consuming untreated tap water, over 40 individuals had already sought medical attention at the hospital.
The Walkerton E. coli outbreak that saw 2,300 people fall ill, and seven die, was the worst public health disaster involving municipal water in Canadian history.
Foodborne Diseases 101

Avian Malaria in the Sub-Antarctic
Avian malaria has recently been discovered in southern Chile and the introduction of beavers decades ago is partially responsible.
Birds on the Brink
Hardly anyone visits the desolate outpost of Coldfoot, one of Alaska’s few communities outside the Arctic Circle accessible by road. Its 34 residents live in rustic accommodations along the Dalton Highway. The town’s highlights include an inn, a café, a gas station and a basic airport with a gravel landing strip. All day long, 18-wheeler fuel trucks thunder by on supply runs between Fairbanks and the oil fields of Prudhoe Bay further north. Some will stop to eat and tank up at Coldfoot because the next human habitation is 234 miles away, a town grimly named Deadhorse.
They say Coldfoot got its name from the days of the 1900 Gold Rush when miners would come as far as this remote settlement before getting “cold feet” and turning back. It’s still a lonely place, but one unexpected visitor showed up recently inside an infected Swainson’s thrush (Catharus ustulatus): the avian malaria parasite, Plasmodium circumflexum.
In 2011, scientists tested 676 birds representing 32 resident and migratory bird species captured from three northern locations in Alaska: Anchorage (61°N), Fairbanks (64°N) and Coldfoot (67°N). In Anchorage and Fairbanks, they found 49 birds infected by Plasmodium parasites. In Anchorage, even resident birds and hatchlings of species such as the boreal chickadee (Poecile hudsonicus), the varied thrush (Zoothera naevia) and the fox sparrow (Passerella iliaca) were found infected. The parasite was also detected in black-capped chickadees (Poecile atricapillus) and a myrtle warbler (Dendroica coronata coronata) in Fairbanks, indicating that transmission had occurred locally.
Vanishing Birds
If you were alive in the year 1970, more than one in four birds in the U.S. and Canada has disappeared within your lifetime.
According to research published online in September by the journal Science, wild bird populations in the continental U.S. and Canada have declined by almost 30% since 1970.
