Bravo Pet Food is recalling several lots and products nationwide because they could be contaminated with Listeria monocytogenes, the Food and Drug Administration said Thursday.

The organism could cause serious and sometimes fatal infections in young children, frail or elderly people, and those with weakened immune systems, though healthy cats and dogs rarely become sick from it.

The recalled products are as follows:
