If you’re eating shellfish this summer, be careful.

An outbreak of vibriosis in Washington has already surpassed record numbers for the month of July because of recent high temperatures and low tides.

The illness is associated with eating raw or undercooked shellfish.

Vibrio bacteria thrive in warm temperatures and grow very quickly.

Symptoms include abdominal cramps, nausea, vomiting and headache, and the illness can occur four hours to four days after eating contaminated shellfish.
