An organic baby food company has voluntarily recalled three varieties of its pureed vegetable products after independent testing detected lead levels exceeding FDA action limits. The affected products were distributed nationwide through grocery stores and online retailers.

The FDA is investigating the source of contamination, with initial analysis suggesting that soil conditions at a contracted farm may be responsible. Parents who have purchased the recalled items should stop feeding them to children immediately.

The company has pledged to implement enhanced heavy metal testing protocols for all incoming ingredients and will publish the results of independent lab tests on its website going forward.
