On October 29, 2021, Mary Ruth's issued a recall of two lots of Mary Ruth's Liquid Probiotic for Infants due to potential contamination with Pseudomonas aeruginosa. This bacterium can cause infection in people who are immunocompromised, and rarely, in infants. According to the company's recall notice, contamination of the two recalled lots was discovered during routine laboratory testing for quality assurance.

Mary Ruth's Liquid Probiotic for Infants (view product photos here) was distributed nationwide through Target, Amazon, and directly from the company's website. It is sold in a brown glass dropper bottle packaged in a box. The recalled products can be identified by the following: UPC barcode number 856645008587, Lot numbers: 100420218 and 100520218.

In 2020, ConsumerLab tested a related liquid probiotic by Mary Ruth's as part of its Probiotic Supplements Review and found it to be contaminated with the same bacterium. More details about this can be found in the Update in ConsumerLab's Probiotics Supplements Review.

Consumers who have the recalled products should not use them and throw them away. They may also contact Mary Ruth's Customer Care Center to request a full refund.
