Anthrax among Canadian Bison

Rhondda Sweetman from Plimmerton Rotary

Our recently-joined member, Dallas New, is a Canadian veterinary epidemiologist and last evening she enthralled us with her study of anthrax among bison.

Firstly, she told us something of the history of epidemiology, which began when Dr John Snow found the cause of a cholera outbreak in London.

Then she explained how bison had recovered from near-extinction in North America, and why anthrax is threatening them. All mammals are vulnerable to anthrax, but cattle and bison are particularly intolerant to it.

Anthrax spores move around, but lodge and persist in the soil. For this reason, dead bison have to be cremated rather carefully so as not to release more spores into the ground. This is quite a challenge as bison are huge and fuel has to be brought to the site by helicopter.

Dallas collected data in the Northwest Territories to find out why outbreaks of anthrax poisoning occur in bison populations.

There were three hypothetical causes: spores could be incubating, especially in hot weather and then bursting out; anthrax could be concentrating in bison ‘wallows’; or bison may always carry anthrax but sometimes have low resistance to it.

Many research projects have inconclusive results and this was one of them. It seems likely that outbreaks occur because of all three factors.

Anyway, Dallas clearly enjoyed her spell in the Canadian wilderness and earned a Master’s degree.

⚠️ DOGS DIE IN HOT CARS. If you love them, don't leave them. ⚠️

The Team from SPCA New Zealand

It's a message we share time and time again, and this year, we're calling on you to help us spread that message further.
Did you know that calls to SPCA about dogs left inside hot cars made up a whopping 11% of all welfare calls last summer? This is a completely preventable issue, and one which is causing hundreds of dogs (often loved pets) to suffer.
Here are some quick facts to share with the dog owners in your life:

👉 The temperature inside a car can heat to over 50°C in less than 15 minutes.
👉 Parking in the shade and cracking windows does little to help on a warm day. Dogs rely on panting to keep cool, which they can't do in a hot car.
👉 This puts dogs at a high risk of heatstroke - a serious condition for dogs, with a mortality rate between 39%-50%.
👉 It is an offence under the Animal Welfare Act to leave a dog in a hot vehicle if they are showing signs of heat stress. You can be fined, and prosecuted.
SPCA has created downloadable resources to help you spread the message even further. Posters, a flyer, and a social media tile can be downloaded from our website here: www.spca.nz...
We encourage you to use these - and ask your local businesses to display the posters if they can. Flyers can be kept in your car and handed out as needed.
This is a community problem, and one we cannot solve alone. Help us to prevent more tragedies this summer by sharing this post.
On behalf of the animals - thank you ❤️
