A recall is underway for certain Topo Chico Mineral Water bottles because they may potentially be contaminated with bacteria, according to Coca-Cola.

Concern that some Topo Chico bottles may contain more than just minerals has prompted Coca-Cola to issue a recall following the discovery of bacteria that could pose health risks to individuals with weakened immune systems.

Among the stores impacted by the Topo Chico mineral water recall are select Costco locations in Texas and Louisiana.
