Muslims have to respect strict dietary regulations, meaning that they should only eat halal food – including meat from animals slaughtered under Islamic practice.
Swiss Muslims can choose between many products bearing the halal label, but a single certification does not exist, which can lead to confusion and abuse.
Those following Islam make up an estimated around 20 per cent of the world's population or more than 1.3 billion people.
This makes the halal food market an attractive one in economic terms. For example, Swiss food giant Nestlé had a turnover of SFr5.3 billion ($5 billion) in the halal food sector in 2008.
