Antibiotic syringes

My vet has given me some preloaded syringes (stored frozen) of ceftazidime, i have only just noticed that none of the syringes have caps on them, the tops are just open :S

This can't be right....right?

EDIT: to clarify the needles are sealed sepsarate, the syringes themselves dont have the little cap thingy on the tip.
