This week, some parents have been scrambling to find a new formula for their babies after a recall expanded.

They say that with supply chain issues, it has been difficult. 

Dr. Nicole Avena is a neuroscientist and just wrote a book on what to feed your baby and toddler. 

She has also been following the Abbott nutrition recall that expanded this week. 

“It's suspected to contain salmonella and also another bacteria known as cronobacter....babies can often get sick if they come in contact with them,” said Avena. 

This is why they were pulled, but now there is a new problem.

 “It is an issue and especially now with you know supply-chain issues, it's not like every store has the shelves stocked with every different type of baby formula that's out there these days,” said Avena. 

She recommends talking to your pediatrician for their recommendations on a switch and talking with other parents. 

“For people who have like extra cans of formula may be that they are not going to use that isn't going to expire for a while, it is a great idea to you know to pass it along to another parent or a friend or somebody that has a baby,” said Avena.

Abbott provided the following statement to News 12: "Our top priority is the health and safety of the infants and children who depend on us. We value the trust parents place in us for high quality and safe nutrition and we’ll do whatever it takes to keep that trust. The cases are under investigation and at this time the cause of the infants’ infections have not been determined. All infant formula products are tested for Cronobacter sakazakii, Salmonella and other pathogens and they must test negative before any product is released. The company keeps retained samples of each batch. We tested retained product samples related to the complaints for Cronobacter sakazakii and Salmonella, and they tested negative."
