Absolutely, we send our food out in insulated boxes and when you open up the box you should see that the food is either still completely frozen or partially frozen. If the food is partially frozen on arrival (i.e. partially defrosted) it is still 100% fine to freeze and use in the fridge as per normal (you may need to cut through a chub to see if still frozen in the middle - or if wanting to be more scientific stick a thermometer in it).If it has fully defrosted, then please get in touch with us.We send the food out at -19 degrees in the insulated liners, so even if the food partially defrosts on the outside edge, in the core it should still be frozen and the overall temperature in the packs won't get above 3/4 degrees celsius if still in the wool liners.We have stress tested the food at various temperatures for 1 - 8 days to check the bacteria / microbial activity to be 100% sure that it is safe in different conditions that we recommend.
