1. A portable system for collecting and extracting a sample from a surface, the system comprising:
a swab having a head at one end of an extended shaft, the extended shaft having a lumen that extends substantially throughout the length of the shaft;
a portable canister having a valve stem and containing pressurized wet foam;
a cradle for housing the canister;
a canister valve actuator connected to the cradle;
a dispensing lever connected to the canister valve actuator;
wherein upon pressing of the dispensing lever, the canister valve actuator presses on the valve stem on the pressurized canister;
wherein as the pressurized foam is introduced at an opposite end of the extended shaft with respect to the head, the wet foam travels through the lumen and elutes samples from the head.
