Air Force Public Health personnel tasked with sampling food suspected of causing illness do not have readily available or standard equipment to perform this task. When presented with a foodborne illness emergency, personnel must scramble to find the necessary sterile tubes, media, and insulated shipping materials. In the present work, three commercially available off-the-shelf cold chain shipping systems were evaluated for temperature holding capacity under the ISCgold Summer and International Safe Transit Association ISTA-7D extreme summer temperature shipping profiles. Despite each manufacturer s claims, which indicated that maintenance of temperatures during transport would be highly likely, none of the evaluated boxes were able to sustain sample temperatures between 2 C and 10 C for 96 hours. The NanoCool long haul shipper lasted 55 hours under the ISTA-7D profile and 38 hours under the ISCgold. ThermoSafe s VIP shippers and Pelican BioThermal s Credo Cube performed similarly VIP shippers maintained sample temperatures under 10 C for 28 hours with the ISTA-7D profile and 15 hours with ISCgold, while the Credo Cube lasted 31 hours under ISTA-7D and 15 hours with ISCgold. Although falling well short of the 96-hour goal, the NanoCool box performed nearly twice as well as the other boxes under the extreme temperature profiles. It has outer dimensions approximately half the size of the other boxes, while providing a similar inner sample space. Additionally, the NanoCool can be re-iced during transit lasting longer than 55 hours with a replaceable chilling unit in the lid, making the unit appropriate for the shipment of all types of temperature-sensitive samples.
