Walmart is recalling Blackstone Parmesan Ranch seasoning due to potential Salmonella contamination. A third-party supplier initiated the recall.

The safety issue compounds investor concerns following Walmart's worst multi-day stock decline in four years. A Q2 profit miss and rising cost pressures initially triggered the sell-off.

No illnesses have been reported to date. The event highlights supply chain vulnerabilities and operational risks within the consumer staples sector.
