Advice on chest freezers. They work best when absolutely packed full, unlike refrigerator freezers.
Models can be standard or frost-free. We get ice build-up in our standard. But I've been told frost-free dries out the food you store, even in vacuum bags.
Your freezer might be smelling a little funky after this episode. We did many washes & rinses with baking soda & vinegar. Don't use bleach! Even that approach won't get rid of the stink entirely.
Get some bundles of the herb bai toey at Makro. Change them every couple of days, freezer closed, turned off. Then get your freezer cold & add a bunch of bai toey with your food. Works for fridge smalls, too.
