On Saturday, Malik said while the business was shut they cleaned and sanitized the cooling towers and refrigeration units.

She said the refrigeration units remain off so the store cannot sell cold or frozen products until the coolers are turned back on, however the store is open for business.

“Public Health has confirmed that we are able to open the store without offering refrigerated or frozen products at this time. We look forward to welcoming our associates and customers to the store,” she said, in an email.

The coolers will not be turned back on until a health inspection takes place.

Cooling towers inside the mall and the Walmart tested positive for legionella bacteria, but are not definitively what made the patients get sick, so the health authority is continuing to investigate, inspect and resample, Bharmal said.

Fraser Health is also awaiting test results to determine whether all seven patients got sick from the same source.

“Our advice at this point isn’t to tell people to stay away from the mall, at all,” he said. “They are taking a lot of proactive measures to clean out the cooling towers.”

Bharmal said legionella is “not entirely unexpected” inside cooling towers because it is found naturally in soil, groundwater and freshwater.

But “even though it’s not expected, it’s not desirable,” he added. He said building water systems need to be periodically closed down for thorough cleaning.

Sébastien Théberge, a spokesman for Ivanhoe Cambridge Inc., which owns Guildford Town Centre, said in an emailed statement that the health and safety of the mall’s customers and employees is top priority, and his firm has fully complied with all requests from Fraser Health.
