Over the past few weeks, Cyclospora has been all over the news, and let’s just say it hasn’t exactly made people crave a salad.
A major cyclosporiasis outbreak in the United States has raised questions among Canadian consumers. Is lettuce safe to eat? Are Canadian-grown products affected? And should we really be worried about every head of lettuce in the produce aisle?
Let’s clear things up. Because no, all lettuce should not be put in the same basket.
First, what is Cyclospora?
Cyclospora cayetanensis is a microscopic parasite that can cause an intestinal illness called cyclosporiasis. People can become infected by consuming contaminated food or water.
According to the Public Health Agency of Canada, washing fresh produce remains an important food-safety practice, but it may not completely remove the parasite. The Agency also recommends choosing fresh produce grown in Canada as one way to reduce the risk, particularly during the spring and summer months.
What is happening in the United States?
The outbreak currently making headlines is in the United States. As of August 5, 2026, the FDA reported 6,358 confirmed illnesses across 15 states, including 278 hospitalizations and two deaths among people with significant underlying health conditions.
The FDA and CDC investigation found an epidemiological link to iceberg lettuce sourced from central Mexico and recalled by Taylor Farms de Mexico. U.S. authorities continue to investigate the outbreak.
That distinction matters: it does not mean that all lettuce sold across North America is affected.
What about Quebec and Canada?
Quebec has also seen an increase in cyclosporiasis cases this summer. According to Quebec Ministry of Health data reported on August 4, 223 cases had been recorded as of August 1, 2026.
But there is an important detail: cases in Quebec were mostly associated with exposure during travel, with Mexico identified as the main destination involved. At the time of the update, no Quebec cases had been linked to the U.S. lettuce outbreak.
In other words, seeing “Cyclospora” and “lettuce” in the same headline does not mean lettuce grown in Quebec is responsible.
Why the origin of your lettuce matters
At Gen V, our lettuce is grown locally in hydroponic greenhouses under controlled conditions. The water used to irrigate our lettuce is potable and UV-filtered as part of our food-safety measures.
Greenhouse growing also provides close control over the production environment. And it is not only us telling consumers to pay attention to origin: the Public Health Agency of Canada specifically lists consuming fresh produce grown in Canada among ways to reduce the risk of cyclosporiasis.
When a food-safety alert makes headlines, where a product comes from is an essential piece of information.
When fear has a very real impact
Confusion between the products involved in an outbreak and lettuce as a whole is already affecting local growers.
In an interview with the Journal de Montréal, Valérie Terrault, Director of Business Development and Marketing at Cultures Gen V, estimated that sales of Quebec lettuce had dropped by about 10% this summer. Her point was simple: local lettuce had been lumped in with products involved in the U.S. outbreak.
Some Quebec growers have even had to reduce prices or destroy unsold crops — a difficult outcome when locally grown produce is not what has been implicated in the ongoing U.S. outbreak.
So, can you keep eating locally grown lettuce?
Yes. Based on the information available at the time of publication, Quebec-grown lettuce has not been implicated in the ongoing U.S. outbreak.
For consumers, the best approach is straightforward: check the product’s origin, follow official recall notices when they are issued, and use safe food-handling practices.
And most importantly, there is no need to break up with salad for the rest of the summer.
