Oxfam wants Cincinnati-based Kroger to be more transparent about where it gets the products it sells in its family of grocery chains.

The aid organization says Kroger is the worst-scoring supermarket group in its scorecard assessing transparency, workers' rights, gender equity and small scale producers.

Oxfam says it compared and rated six chains: Walmart, Kroger, Albertsons, Costco, Whole Foods and Ahold Delhaize.

Oxfam says in a statement it wants Kroger to "adopt stronger policies," including "disclosing gender-pay ratios and providing better opportunities for women workers in their supply chains, being more transparent around its suppliers by releasing their names, and empowering small-scale producers within their supply chains."

WVXU reached out to Kroger officials for comment. A company spokeswoman says this is an earnings week and therefor the company is in a "quiet period."

Kroger reported strong earnings Thursday, with a net of $2.0 billion for the first quarter. That figure includes the sale of its convience store unit.
