Cyclospora outbreak: US agriculture secretary says food supply is ‘safest in the world’ amid lettuce scare

The United States is investigating a Cyclospora outbreak that has raised concerns over contaminated lettuce, prompting reassurance from US Agriculture Secretary Brooke Rollins, who said the nation's food supply remains "the safest in the world."

The comments come as federal and state health agencies continue to identify the source of infections while monitoring additional cases linked to the foodborne parasite.

What did the agriculture secretary say?

Addressing concerns surrounding the outbreak, Agriculture Secretary Brooke Rollins said the US has one of the world's most robust food safety systems and that outbreaks, while concerning, are detected through extensive surveillance and testing.

She stressed that regulators and public health officials are working closely to identify the source of contamination and remove affected products from the supply chain if necessary.

What is Cyclospora?

Cyclospora cayetanensis is a microscopic parasite that causes cyclospora infection (cycloporosis), an intestinal illness spread through contaminated food or water.

People typically become infected after consuming fresh produce contaminated with the parasite.

Common symptoms include:

• Persistent watery diarrhoea

• Loss of appetite

• Stomach cramps

• Nausea

• Fatigue

• Weight loss

• Low-grade fever in some cases

Symptoms often appear about one week after exposure and can last for several weeks if left untreated.

Why is lettuce under scrutiny?

Health officials are investigating whether lettuce served or sold through certain supply chains may be associated with the reported illnesses.

At this stage, investigators are working to determine the exact source of contamination. Authorities have advised consumers to follow updates from public health agencies regarding any recalls or food safety advisories.

No final determination has been announced on the specific origin of the outbreak.

What should consumers do?

Public health experts recommend:

• Washing fresh produce thoroughly before consumption, although washing may not completely remove Cyclospora.

• Following official recall notices and food safety alerts.

• Seeking medical attention if prolonged diarrhoea or other symptoms develop after eating fresh produce.

Cyclospora infections are treatable, and healthcare providers may prescribe antibiotics when appropriate.

Investigation continues

Federal agencies, including the US Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA) and the US Department of Agriculture (USDA), continue to investigate the outbreak.

Officials have emphasised that consumers should rely on verified public health guidance while the investigation remains ongoing.
