depends on your location. if you are in kl, food is under dbkl. if you do go setup a stall, without dbkl license they can come with a lorry and take away every of yours & fine you. it is under lesen penjaja or something (street stall license).

some license can be under your name, some requires ssm (company).

if you have a shop/venue/factory to cook/produce food you need a central kitchen license. goto dbkl (or which ever your location is), talk to them. they r very nice n helpful. also always remember to take down the dbkl officer's name, department so in the event if u enter into court (or some other department guy ask) u can always say u get that info from xxx from which department.

for food venue (retail), you WILL need to get approval from several departments (dbkl will advise you), like ministry of health clearance (vaccination), bomba clearance (fire prevention) & others, plus onsite inspection from all the departments.

to those who suggest go do THEN figure out the legal aspect later...  duh... always check with the local authorities first, as that is your responsibility. the court of law in malaysia => ignorance is not an excuse
