President Donald Trump joked on Friday, July 24, that he might impose tariffs on Mexico and Canada to address two distinct issues currently impacting millions of Americans: a widespread foodborne illness outbreak and air quality concerns caused by wildfire smoke drifting across the border. The remarks were made during an Oval Office press conference after Fox News White House correspondent Peter Doocy asked the president when it would be safe to consume lettuce again.
Responding to the inquiry, Trump stated that he would consider placing a major tariff on Mexico due to the lettuce-related health concerns, and a significant tariff on Canada regarding the smoke. The president noted that he had informed Canadian officials that they must take action, emphasizing that the United States had not previously experienced such problems with Canada.
The comments come as federal health agencies continue to investigate a cyclosporiasis outbreak. According to a CDC update released on July 24, there have been 4,173 laboratory-confirmed cases of the infection, which is caused by the microscopic parasite Cyclospora and is known to cause severe diarrhea, reported since May 1. Additionally, the CDC indicated that another 7,400 cases, primarily concentrated in Michigan and Ohio, remain unconfirmed. Research suggests that cases have surfaced in nearly every state, with only four states reporting no infections.
Simultaneously, smoke from Canadian wildfires has periodically degraded air quality throughout the United States. In 2023, more than 9 million acres of Canadian forest burned, resulting in air quality alerts for approximately 75 million people across the Midwest, Northeast, and Southeast. Recent incidents have left skies in various U.S. regions blackened or tinted by orange haze. On July 15, smoke from these out-of-control fires led to Toronto experiencing the worst air pollution globally, while New York City ranked fifth worst according to data from the Swiss air quality technology company IQAir.
