Can you thaw and then refreeze meat?

Today I read an article on whether or not you can thaw and refreeze meat which appeared on the new.com.au site.

http://www.news.com.au/lifestyle/food/eat/can-you-thaw-and-refreeze-meat-6-food-safety-myths-busted/news-story/feac0341b79bed4c58f7b803ba1a8c69

The problem is the first myth in the article didn't quite make sense and didn't really answer the question.

Myth 1: If you thaw meat, you can’t refreeze it.

FALSE. According to the CSIRO, it’s perfectly safe to refreeze defrosted meat or chicken or any frozen food as long as it was defrosted in a fridge running at five degrees C or below. The only thing you may compromise is a bit of taste, as defrosted meat can become slightly watery.

If there’s anything to watch, it’s the pre-freezer ‘steam’. If you cook defrosted meat and refreeze it into a container while hot, you’ll create condensation — which is the perfect breeding ground for bacteria. So wait for the steam to subside before packaging.

I thought I'd then look for the source of the material from the CSIRO. The same article on the CSIRO made sense.

Myth 1: if you’ve defrosted frozen meat or chicken you can’t refreeze it

From a safety point of view, it is fine to refreeze defrosted meat or chicken or any frozen food as long as it was defrosted in a fridge running at 5°C or below. Some quality may be lost by defrosting then refreezing foods as the cells break down a little and the food can become slightly watery.

Another option is to cook the defrosted food and then divide into small portions and refreeze once it has stopped steaming. Steam in a closed container leads to condensation, which can result in pools of water forming. This, combined with the nutrients in the food, creates the perfect environment for microbial growth. So it’s always best to wait about 30 minutes before refrigerating or freezing hot food.

Plan ahead so food can be defrosted in the fridge, especially with large items such as a frozen turkey or roll of meat. If left on the bench, the external surface could be at room temperature and micro-organisms could be growing rapidly while the centre of the piece is still frozen!

This is an example of how you have to be careful when material is edited and republished on other sites. The news.com.au site didn't make sense as they had removed the paragraph starting with "Another option". The news.com.au article went straight from refreezing thawed meat to talking about steam being a problem. Nothing about cooking and thus the disconnected meant it didn't make sense and wasn't advice I'd follow. The CSIRO article was complete, made sense and gives me confidence I can follow the advice.

So yes, according to the CSIRO you can thaw and refreeze meat, as long as you follow their guidance.
