The recommended method for transporting a specimen that requires chilling is by using a container immersed in a slurry of crushed ice and water. This method ensures that the temperature of the specimen is maintained consistently at a low level, which is crucial for preserving its integrity and preventing any biological or chemical changes that could occur if the specimen warmed up.

A slurry of ice and water provides an optimal cooling environment because it allows for better thermal conductivity compared to just ice or ice alone. This mixture keeps the specimen at a stable, cold temperature throughout transportation, which is vital for tests that are sensitive to temperature fluctuations.

In contrast, storing a container at room temperature may lead to increased temperatures that compromise the specimen's viability and reliability of the subsequent test results. Similarly, placing the specimen in a refrigerator may not keep it cold enough over longer transport durations, as it might not be able to maintain the low temperature required for proper preservation. Using dry ice is generally reserved for specimens that need to be kept at extremely low temperatures, making it inappropriate for most standard chilling requirements. Therefore, the slurry of crushed ice and water is the most effective and reliable method for transporting specimens needing chilling.
