A container (10) for the storage of perishable foodstuffs is chilled by means of a liquefied gas comprising a mixture of oxygen and nitrogen which when totally vaporised has an oxygen concentration of between 15 and 22%, the remaining concentration being substantially of nitrogen. Such an atmosphere is breathable, and hence avoids the problems associated with non breathable chilling atmospheres.
