A FOOD safety expert has revealed the hidden sign your meat is rotten - and how to avoid getting sick.
Sylvia Anderson is one of the top in her field and broke down ways to keep yourself safe from food poisoning.
She explained how to spot your meat is past the point of being edible - and it's quite simple.
The food safety expert explained it's a matter of "using your senses".
Sylvia said by looking at the colour of particular raw meats, or their texture, you can tell whether they're rotten or not.

She told MailOnline: "When anything goes off it's called food spoilage.
"For example, when chicken goes off it goes green while when meat goes off it goes slimy.
"It will have white dots on it, and it will go darker. You can tell by the appearance and colour of the food."
Sylvia added: "If you buy fresh pork most people with common sense can tell if there's a rancid smell or the colour changes."
The pro, who is one of the leading food safety experts in the UK, said it can be harder to tell if cooked meat in a ready meal is still good to eat or not.
She said: "That's more dangerous because the customer won't see that.
"If it's ready to eat, it might already be partially cooked. That means it's been cooked, chilled and the customer will buy and reheat.
"They won't know because they can't smell it and eat it and then have food poisoning.
"If it's a pork dish in a state of rawness you can tell straight away. But if it's already been processed in some sort of manner and it's something you stick in the oven or reheat... you're going to find out when you're vomiting and having diarrhoea."
