A recent discovery found nine foul food additions in everyday foods.
Beaver anal gland secretions
A variety of products including strands of hair, antifreeze, beetles, wood, petrol (TBHQ), wax, flame retardant and artificial caramel colouring have been found in a number of every day food, according to Alex Kann from Community Channel who carried out the research as part of the Real's Food Revolution season.
However, one of the most shocking discoveries was beaver anal gland secretions, also known as castoreum, which has been used to flavour fizzy drinks.
And the additive, mixed with urine, is what the woodland animals use to mark their territory and to attract mates.
According to befoodsmart.com, catoreum can be found in alcoholic beverages, baked goods, frozen dairy products, chewing gum, sweets, meat products, pudding, gelatin, ice cream, vanilla flavouring and raspberry-flavoured food.
More shockingly, the ingredient is listed as a ''natural flavouring''.
