A biological agent growth-limiting and cross contamination suppressing foaming assembly (10). The foaming assembly (10) comprises a disposable foamableliquid transport and foaming cartridge (40) and a housing (70) cooperatively used with the cartridge to produce and dispense foam from the cartridge. The cartridge comprises a low-cost package comprising a molded tray (300) which provides cavities (e.g. 314, 316, 328, 348, 350, 354, 356, 358, 362) for liquid containing chambers, air and liquid communicating channels, and initially sealed but frangible ports and a liquid impervious sheet (302) which covers a face of the tray to seal otherwise open portions of the chambers, channels and ports. The housing comprises a vertical wall mounting plate (60), a cartridge-accommodating and servicing cover (72) hingeably affixed to the mounting plate, a pump (30) which provides pressurized gas to produce the foam within the cartridge, and sharpened stems or shafts (284, 294) to open the frangible ports. Foamable-liquid is stored within the cartridge during shipment, foamed within the cartridge under pressure from the pump, and dispensed as a foam from a spout (40) which is a part of the tray.
