(NBC News) – Health officials in San Diego County, California say a 2-year-old boy died last week due to an E. coli infection.
Three other children, ages 9 to 13, have also been sickened by the bacteria.
Officials say all four visited the San Diego County Fair between June 8th and June 15th, and all of them visited animal exhibits, a petting zoo or had other contact with livestock at the fair.
“Although no specific animal activity has been implicated at this time, out of an abundance of caution the petting zoo has been closed and public exposure to animals has been restricted until the fair closes,” San Diego County Health Officer Dr. Wilma Wooten announced.
The boy who died got sick on June 19th, four days after visiting the fair.
Health inspectors are trying to determine the source of bacteria, but say all food stands at the fair have been inspected and found to be safe.
