Out of an abundance of caution, MaryRuth’s is voluntarily recalling two lots of its liquid probiotic for infants (1oz) due to possibility of contamination byPseudomonas aeruginosa,according to a company announcement posted by FDA.

P. aeruginosais a microorganism that, if ingested, can cause infection in immunocompromised individuals or, rarely, in young infants, although infections in immunocompromised infants are generally limited to hospital settings. It is possible, in those settings, that the infant’s gut will not be able to preventP. aeruginosa from gaining access to the blood, which can result in serious adverse health consequences.

The recall affects two lots of the product: Lot #100420218 and Lot #100520218, UPC barcode number 856645008587. Lot numbers are located on the side of the bottle and on the bottom of the outer container in which the product is sold. The product is distributed through Target, Amazon, and the company’s website.

MaryRuth’s is asking customers to throw away products from the affected lot numbers, and to contact the company'sCustomer Care Centerto request a full refund.

The company discovered the potential issue during routine laboratory testing. The only complaint MaryRuth’s has received so far was one report of temporary diarrhea in an older infant after consuming the product, which the company does not believe was related to the presence of the microorganism.

“We apologize for any concern or inconvenience this situation causes our customers and are here to support them,” said MaryRuth’s Founder and CEO MaryRuth Ghiyam, in the announcement. “MaryRuth’s is dedicated to the safety, health and welfare of its customers above all else, and has invested heavily, and continues to invest, in safety and quality protocols to ensure we produce only the best products.
