maintenance logs at the pool were maintained and reported no incidents of fecal contamination.

In light of the confirmed cases, it is not clear if the health district has subsequently tested the pool’s water for E. Coli — on August 8, it was reported that the health district was exploring the feasibility of conducting E. coli testing on the water.

“E.coli, it can be transmitted either by contaminated water or by contaminated food,” said Vaidehi Shah, senior epidemiologist with the health district. “It’s possible that at that point in time, when the exposure happened, it’s possible that the pool was contaminated, or there was a food source that was contaminated that could have caused people to fall sick.”

Nonetheless, health officials have linked the outbreak to the swimming pool.

“We are doing an investigation here,” Shah said. “There is a correlation here, but there’s no causation yet.”
