These so-called “buttergate” anecdotes have been spreading online, with many Canadians complaining that their butter does not soften at room temperature.
Food experts have churned up palm fat in cow feed as a likely culprit.
The dairy industry insists the claims are unfounded, but has created a working group to seek answers.
Buttergate began with a question posed on Twitter by Canadian cookbook author Julie Van Rosendaal: “Have you noticed it’s no longer soft at room temperature?”
Hundreds of home cooks responded with similar butter woes.
Something is up with our butter supply, and I’m going to get to the bottom of it. Have you noticed it’s no longer soft at room temperature? Watery? Rubbery? pic.twitter.com/AblDzGiRQY

Ms Van Rosendaal suggested in a Globe and Mail column last week that a higher demand for butter in the pandemic led to changes in livestock feed, as farmers sought to increase production.
Demand certainly has been on the rise during the pandemic.
The country’s dairy sector – a major presence in all 10 provinces – determines its production quotas based upon demand forecasts. With more Canadians staying home, demand for butter rose by over 12% in 2020, according to Dairy Farmers of Canada.
Adding palm oil-based energy supplements to cow feed is a decades-old practice said to increase the milk output of cows and increase the milk’s fat content.
Since the summer, hundreds of farmers around the country have stepped up their use of palm oil substances in an attempt to boost supply.
Canada’s Dairy Processors Association told Real Agriculture there have been no changes to butter production itself nor national ingredient regulations.
Little research has been done on the true impact of palm oil in dairy, but agricultural experts say butter made from cows fed with palm oil has a higher melting point and, therefore, may be harder to spread at room temperature.
“A Buttergate is not what the industry needs, or what Canadians deserve,” wrote Sylvain Charlebois, senior director at Dalhousie University’s Agri-Food Analytics Lab, in a widely published opinion piece this week that argues most of the country’s butter has definitely gotten harder.
Mr Charlebois noted that palm fat is a legal ingredient in dairy cow feed, but research shows palm oil can increase heart disease risk in people.
Its production also harms the environment, he said, making it an “ethically questionable” practice for the dairy industry, which is heavily subsidised by Canadian taxpayers.
“Let us hope the dairy industry can clean itself up before its moral contract with Canadians is permanently damaged,” he concluded.
Responding to the complaints, the Dairy Farmers of Canada lobbying group released a statement on Friday arguing palm products “help provide energy to cows and no undesirable effects have been identified arising from its use in cows’ feed rations”.
They also noted that farmers in other countries, including the UK and United States, also use palm product supplements.
The group said it would nevertheless assemble an expert committee – composed of various dairy stakeholders, including consumers – to address the concerns.
