Question: Is it safe to feed wild caught worms?

[BartuYuksel]

I got some worms online, but they are wild caught (no bred worms are ever available). I was wondering if it is OK to feed them to my salamandra infraimmaculata. If not, what can I do to make them OK?

it can be risky using wild earthworms as it isn't known what condition the soil that they are in is like (there could be traces of insecticides among other chemicals in the substrate), the worms would need to be kept in fresh regularly replaced soil/compost for a period of time to ensure any residue is removed, this may take up to a month (equivalent to quarantining them)
