Food waste is definitely a ‘thing’ – a recent U.N. study found that the average Canadian wastes 79 kilograms of food per year. And as Jo-Ann notes in her May article, we may be wasting 13.5% more food at home since the start of the pandemic.
A recent article by Reynold Bergen in Country Guide notes that food loss and waste are not limited to unwanted leftovers in your fridge, produce discarded from grocery store shelves, or unwanted meals disposed of from restaurants. They are more broadly and correctly defined as any crop or livestock product that doesn’t directly reach a human mouth. By this definition, it’s clear that food loss and waste occurs well before the grocery store; primary production, storage, transportation and processing are all sources of food waste and loss.
So what exactly is going on with food and feed waste at the farm level? As we all know, farmers are amongst the most savvy and frugal business-people on the planet. They are also the earth’s first and most ardent environmentalists, recognizing that every action they take affects not only this year’s crop or this week’s load of hogs, but also their ability to successfully farm into the future.
These smart, thrifty, and environmentally conscious farmers are in fact doing innovative and in some cases strange things to help manage waste on the farm. Using the broader definition of food waste postulated by Mr. Bergen, here are just a few of the innovative ways that farmers are reducing waste and making better use of our earth’s scarce resources.
Cattle love Skittles – it’s true!
In 2017, a truck lost its load of red Skittles in the rain on a country road in Wisconsin. Hundreds of thousands of the sweet treats spilled on the roadway, but what was most surprising was where the Skittles were headed in the first place: a local diary operation, where they were to be used as feed.
Turns out the dairy producer routinely procured Skittles that did not make the grade for commercial sale, for use in his dairy rations. The substandard candy, which would otherwise have ended up in local landfill, provides a cost-effective source of sugar which is used as energy to break down bacteria, fiber and protein found in a mixed ration.
Beyond Skittles, dairy and beef producers will often purchase food by-products or off-spec foodstuffs for use in rations. The type of by-product depends on what’s available locally at any given time of year, and what nutritional value it can add to the ration. I remember my dad obtaining pumpkins and sweet peas that didn’t meet the quality standards required for human use from local cannery Stokely-Van Camp. These were loaded into a pit silo, covered with plastic and fed to our herd over the course of the year.
All in all, food waste or substandard produce that ends up in a cattle beast rather than a landfill is a win all around.

Livestock doing their part for the planet
An ongoing study by Dr. Kim Ominski and collaborators from the Universities of Manitoba and Lethbridge and Agriculture Canada is examining ways that livestock may actually be helping to reduce food loss and waste. Cattle, for example, have some unique advantages that allow them to help deal with by-products that might otherwise go to waste. Because of the unique structure of their digestive system, cattle and other ruminants can consume high fibre feedstuffs such as distiller’s grains (a by-product of the distilling process), and oat, soybean and sunflower hulls that have no commercial value, and cannot be effectively digested by other species such as hogs or chickens. Because they can effectively digest these high-fibre by-products, cattle can consume up to 50 per cent distillers grains in their diet, much more than pigs (15 per cent) or chickens (10 per cent). The net result: waste grains end up on your barbeque, as opposed to the local landfill.
Lost in the Field
A final and significant source of farm-level food waste is related to unharvested crops. Each spring, farmers plant their crops with hopes of a bountiful harvest. But nature has a funny way of intervening. Thousands of hectares of crops go to waste every year due to a variety of factors: untimely weather that disrupts harvest, insect or disease damage that makes crops unviable, or simple economics – at times drops in market prices or shortages of labour can make it more cost effective to leave the crop in the field, burn it off or plow it under, rather than proceed with harvest.
Part of the solution to this chronic problem comes from groups like US-based Farm to Pantry, which last year claims to have ‘rescued’ over 200,000 pounds of produce. It does this through the use of volunteer gleaners, who harvest this ‘lost produce’ by hand, and deliver it to recipients like homeless shelters and food banks.
Canada’s Second Harvest runs a broader program, rescuing fresh food from farm gate all the way though retail. The group, which claims that 58% of all food produced in Canada is either wasted or lost, has rescued over 177 million pounds of healthy food over the past 35 years, keeping it out of landfills and preventing unnecessary greenhouse gases from entering the atmosphere.
The bottom line
From red Skittles on the highway to sunflower husks to cantaloupes rescued from flooded fields, Canada’s agriculture sector is playing a strong role in mitigating food waste and loss, from the farm gate forward. While food waste is generally associated with grocery stores and restaurants, it’s clear that primary agriculture has a critical role to play too. And whether it’s for economic or environmental reasons, Canadian farmers are stepping up!
In the 2019 Nourish Network Trend Report, we covered three trends/shifts that we believed would impact the Canadian agricultural sector this year and into the future – Canada’s international agri-food industry, precision agriculture, and the public’s trust of Canadian agriculture. As we head into 2020, we’re following up on how these trends are playing out. … Read More
