Lakesha was culturing bacteria. She used aseptic technique to make sure there was no contamination. When she was finished, she used water to clean the surface of her table. She then put the sample in the incubator, removed her gloves, and washed her hands with soap and water. Which error did Lakesha make in her process?
Answer
A
A student should not culture bacteria in the lab.
B
Aseptic technique is used for chemical spills.
C
She does not need to wash her hands after culturing bacteria.
D
She should be using a disinfectant on her table, not just water.
Explanation
Water alone does not reliably kill or remove bacteria from the work surface. After culturing bacteria, Lakesha should disinfect the table with an appropriate disinfectant. Washing her hands after removing her gloves is also a correct safety step.
