Shreddies

Shreddies are a breakfast cereal from Canada and the UK made from lattices of wholegrain wheat.
Manufacture.
In Canada, production began in 1939 at Lewis Avenue, Niagara Falls, Ontario. Shreddies were produced under the Nabisco name until the brand in Canada was purchased in 1993 by Post Cereals, whose parent company in 1995 became Kraft General Foods, which sold Post to Ralcorp in 2008 and is now Post Foods Canada Corp., a unit of Post Holdings, which was spun off from Ralcorp in 2012.
In the United Kingdom, the cereal was first produced by Nabisco's former UK division, but is now made by Cereal Partners under the Nestlé brand at Welwyn Garden City. The factory opened in 1926 and began making Shreddies in 1953. The site was briefly owned by Rank Hovis McDougall in 1988, which sold it to Cereal Partners in 1990. Nestlé's site at Staverton started making Shreddies in 1998, and is where all production was moved in 2007.
The cereal is marketed with the whole grain symbol, as part of a marketing campaign emphasising the healthiness of the cereal. Wheat for Shreddies is sourced from over 500 different farms within the UK.
Sugared, chocolate and honey-flavoured versions of the cereal are available in the UK as Frosted Shreddies, Coco Shreddies, and Honey Shreddies, an orange-flavoured and coconut infused version of the Coco Shreddies have also become available recently. The former advertising slogan in the UK was: "Keeps hunger locked up until lunch". The advertising slogan for the Frosted and Coco Shreddies was: "Too tasty for geeks".
Collectables.
In January 2012, boxes of Shreddies dating from the early 1970s were reported to be selling on eBay, after being discovered in a village shop. They were reported to have been selling for about £160 per box on eBay.
In popular culture.
Shreddies featured as a plot device in the Canadian mockumentary television series created and directed by Mike Clattenburg, the" Trailer Park Boys". Shreddies were part of the survival supplies Julian, Ricky, and Bubbles sent with Jacob Collins and his Boys on their outing to lay a model train track across the Canada- US border in the episode "We Can't Call People Without Wings Angels, So We Call Them Friends". Other supplies sent with them included liquorice and cannabis. The train track Jacob and his minions constructed was intended for use in smuggling cannabis across the Canada - US border. 
In season 1, episode 4 of the Netflix series "Black Summer", “Alone,” Lance can be seen in the episode titled “Oasis,” pushing a cart loaded with groceries including Post Shreddies and Miller Lite around an empty grocery store before unloading the Shreddies at the (unmanned) checkout counter. Realizing he needs a can opener for the canned goods he had picked up, he then heads back into the aisles to find one, only to hear (and then see) a zombie who then sees him and gives chase. As a result, he is forced to leave his Shreddies (and the rest of his supplies) behind and take refuge on the roof of a school bus in a nearby school bus company parking area.
Shreddies featured repeatedly in season 1 of the Canadian television series "Crawford".
