All dairy and meat (including poultry) products are to be kept completely separate at all times
Meat and poultry require Shechita (Jewish method of ritual slaughter), washing and salting under the supervision of a recognised kosher authority
Dairy certification can either be Halav Stam (non supervised milk from a Kosher animal) or Halav Yisrael (supervised milk from a Kosher animal)
Foods that are neither dairy or meat are given the term ‘Parev’ (neutral). These include eggs, fish, vegetables and other products
Passover is an eight-day period with additional Kosher requirements surrounding the use of grain ingredients. This requires a separate ‘Kosher for Passover’ certification
