Summary:Carnitine has beneficial vitamin-like qualities and functions as a compatible solute. The presence of L-carnitine in infant formula significantly promoted the growth of Listeria monocytogenes at 7C, whereas disruption of the genes for carnitine and glycine betaine uptake compromised growth of the L. monocytogenes mutant in formula containing carnitine that was stored at 7C. Thus, addition of carnitine to baby formula may pose a potential food safety risk.
