Why do we need private Halal certification body when India has a food safety authority ?

The Food Safety and Standards Authority of India (FSSAI) is an autonomous body under the Ministry of Health & Family Welfare, Government of India; Maharashtra has the Food and Drugs Administration (FDA); as do other states. These bodies are entrusted with the task of certifying food safety and practices. They have stringent standards that need to be upheld to be certified; standards which are not limited to just the product but include the place of production, fire safety and even waste management. These certificates also come with a fee. So while the secular government has provisions and necessary bodies to audit and attest food standards, how were Islamic private bodies granted permission to issue halal certifications? These private bodies do not follow any of the government regulations, but stick to religious guidelines to issue certificates. So doesn’t the government think that the ‘fee’ that they collect to issue ‘certificates’ illegal?
