Final answer:
When your fuel samples are contaminated, confirm the contamination, compare results with peers to identify patterns, document the contaminated food samples, and report the findings to a supervisor while following safety protocols.
Step-by-step explanation:
If your first fuel samples are contaminated, it is important to follow a systematic approach. First, ensure that the contamination is not due to a procedural error. Repeat the testing if necessary to confirm the result. If contamination is confirmed, document the types of contaminants found and compare these results with those obtained by others in your lab who tested different food samples. This can help determine if there is a common source or specific food types that are more prone to contamination.
To determine the extent of contamination within the samples tested by your lab group, compile a list of all the test results. Identify and list out the specific food samples that were found to be contaminated with bacteria. Discuss the outcomes with your peers to assess the prevalence of contamination, identify any patterns, or commonalities among the contaminated samples.
It is vital to practice good lab protocols to avoid cross-contamination and handle all samples with care to prevent the spread of bacteria. Finally, report the findings to your instructor or supervisor and follow any instructions given for further action or disposal of the contaminated samples.
