Yes. Suitable secure packaging and separation reduce contamination during loading, storage and eventual thawing. Freezing does not remove the need for food hygiene.
What the observation tells you
A leaking raw-food pack can contaminate another wrapper or a drawer even if the liquid later freezes. When the food thaws, that contamination can spread. Loose unlabelled portions also make it easier to confuse food that needs cooking with food intended to be ready to eat.
A useful next step
Package and label items clearly, follow storage instructions and clean spills using the approved appliance method. Plan thawing so raw juices cannot reach ready-to-eat food.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
