CDC tracks five dangerous diarrheal outbreaks across the U.S.

Public health officials are warning about five diarrheal illnesses under investigation by the CDC's epidemiology team. The outbreaks, set to be detailed in August, include infections linked to food, travel, and animal contact. Experts stress that simple hygiene and food safety measures can greatly reduce the risk of infection.

The five illnesses being tracked include Cyclospora infections tied to international travel, with around 30 cases reported across 11 states since June. Another outbreak involves Salmonella Newport, which has sickened 281 people in 36 states after they ate Mexican-style cucumbers. E. coli O157:H7, connected to organic carrots, has caused 38 cases in 12 states, while Listeria from Boar's Head deli meats has led to 61 infections across 18 states. A separate Salmonella strain, Africana, is spreading through contact with backyard poultry.

To prevent these illnesses, thorough handwashing remains one of the best defences. The CDC recommends scrubbing all parts of the hands—including under nails, the backs, and wrists—especially after handling animals, changing nappies, or preparing food. Cooking meat to safe internal temperatures and keeping raw meat juices away from produce also cuts infection risks. Swimming or wading in contaminated water should be avoided, particularly for those already ill. People with diarrheal symptoms are advised not to cook for others or enter shared water sources. Washing fruits and vegetables properly further lowers the chance of infection.

Anyone showing signs of diarrheal illness should consult their GP promptly. The CDC's upcoming report in August will provide more details on the outbreaks and prevention strategies. Following basic hygiene and food safety rules can help limit the spread of these infections.
