Salmonella contagion is spread by the fecal to oral route. It can not be
transmitted through *breastfeeding* unless a carrier touches the breast
with unclean hands before the baby's mouth is in contact with it.
Salmonella in the food supply comes from fecal contamination. Bacteria from
the feces of an infected carrier are introduced into the food at some point
between production and consumption and unless the food is heat treated in
between contamination and consumption, whoever ingests the food may fall
ill. Two cases so far apart in the same NICU would seem to point to
something other than food as a vector. More likely an asymptomatic carrier
on staff  with poor hand hygiene, yuck.
NICU patients receiving expressed breastmilk that is fed by someone else in
the mother's absence could be infected through the milk or through the
utensils/equipment used to deliver the feed.
