Manitoba Identifies Human Cases Of Influenza Variants Normally Found In Pigs

May 03, 2021

Two separate cases of variant influenza viruses have been found in two unrelated individuals in different communities in southern Manitoba.

One is a case of human influenza A(H1N2)v and one is a case of human influenza A(H1N1)v, which are rarely seen in humans. These two flu viruses are related to influenza viruses that circulate in pigs.

While these investigations are ongoing, the current assessment is that there is no increased risk to Canadians or the food supply chain at this time.

The viruses were detected in early April after the two individuals independently sought testing after developing an influenza-like illness. The tests came back negative for COVID-19. Both had either direct or indirect exposures to pigs.

Based on available evidence, the current assessment is that there is no increased risk to people, with no evidence of sustained human-to-human transmission at this time.

In a statement, Manitoba Pork says that H1N1 and H1N2 are not food-borne illnesses and neither virus can be transmitted by eating pork. The group is reminding hog farmers to continue to follow biosecurity protocols, including frequent handwashing, wearing appropriate personal protective equipment, and avoiding contact with livestock if you have flu-like symptoms.

Sporadic human cases of variant influenza have been reported over the past decade in North America.

Human influenza A(H1N2)v is rarely seen in humans, with only 29 cases reported globally since 2005, and no cases in Canada until one was reported in Alberta in October 2020. Human influenza A(H1N1)v is also rarely seen in humans. This is the second ever case reported in Canada; the first was reported in Ontario in September 2012. Two human influenza A(H1N1)v cases were detected in the U.S. during the 2020-21 season.

Health officials, in conjunction with Manitoba Agriculture and Resource Development, have launched a public health investigation to determine the source of the viruses and to verify that no spread has occurred. The Manitoba government will also continue working closely with the Public Health Agency of Canada and other partners across Canada to share information about these cases.

Video: Why Seed Analysts are Thriving Under Seeds Canada

Last month in Edmonton, Alta., industry leaders and stakeholders gathered to discuss the evolving landscape of the seed industry at Seeds Canada’s annual conference. Among them was Sarah Foster, president of 2020 Seed Labs and the new vice-president of Seeds Canada.

Foster, who has been on the board of Seeds Canada for over a year, has witnessed firsthand the challenges and opportunities that come with the formation of the organization. Seeds Canada was established just over three years ago through the merger of multiple seed industry groups, including the Commercial Seed Analysts Association of Canada (CSAAC). Since then, the organization has been working to define its priorities and solidify its role in the industry.

“The challenge has been allowing the dust to settle after the merger,” Foster explained. “We’ve been focused on identifying what our priorities should be and ensuring that our members, especially the seed analysts, are getting what they need to continue their professional work.”

One of the recent highlights was a pre-conference event where the three major seed labs in Alberta — 20/20 Seed Labs, SGS Canada and Seed Check — opened their doors to members. The event saw a record number of seed analysts and business professionals in attendance. Foster emphasized the importance of this transparency, stating, “It’s crucial for people to see what goes on behind the scenes. We’re an open book now, and that openness helps build trust and understanding within the industry.”

The event also featured an environmental scan and a series of discussions that fostered strong communication among attendees. According to Foster, the dialogue was both encouraging and inspiring.

“A lot of people were really inspired by the fact that Seeds Canada is moving ahead with its agenda. The seed analysts, who have always worked diligently in the background, are now being recognized more prominently,” she said.

Before the merger, seed analysts were represented by CSAAC. Now, as part of Seeds Canada, they are finding their place within the larger organization. Foster believes that the integration has been successful, noting, “I think we’re thriving. You only need to look south of the border, where similar consolidations are happening.”

As Seeds Canada continues to evolve, Foster remains optimistic about the future. “I want to be totally transparent with anyone who is a seed analyst — I’ve got your back. We’re moving in a positive direction, and we’ll do everything we can to meet the needs of our members,” she said.
