Just been left in an untenable situation where there was nobody else around so I had no choice but to help a sheep stuck lambing.
I only held the head end, wore rubber gloves, have striped and washed my outer clothes (down to bra and knickers) and used steriliser all over my hands and any part that went near the sheep.
It should be ok shouldn’t it?
Please don’t answer this if it’s just to tell me about nhs recommendations as I know about them hence every precaution I could think of.
