Back in April, employees at H-E-B’s grocery stores were scrambling to pull Blue Bell ice cream from their shelves. Come September, they may be rushing to put it back.

Blue Bell Creameries began shipping ice cream from its facility in Sylacauga, Ala., on Tuesday, more than three months after an outbreak of listeria contamination nearly devastated the Southwestern ice cream favorite and forced the closing of all four of its plants.

But while this week’s move put frozen treats one step closer to consumers, the company said it did not yet know which stores would ultimately restock their shelves with Blue Bell flavors, or how soon.

“We’ve still got to meet with our retailers,” said Joe Robertson, Blue Bell’s advertising and public relations manager. “Retailers have been very supportive of us.”
