Common problems identified in audits by the U.S. Food and Drug Administration (FDA) include which of the following:

The U.S. Food and Drug Administration (FDA) often identifies several common problems during audits. These include:

1. Inadequate or inaccurate record keeping: This is a common issue found in many audits. Companies may not have complete records of their processes, or the records they do have may contain errors.

2. Non-compliance with Good Manufacturing Practices (GMP): The FDA has established GMP guidelines that companies must follow to ensure their products are consistently high in quality. Non-compliance with these guidelines is a frequent issue.

3. Lack of or inadequate Standard Operating Procedures (SOPs): SOPs are crucial for ensuring consistency and quality in manufacturing. If a company doesn't have these in place, or if they're not adequate, this can be a major issue.

4. Inadequate training of employees: Employees must be properly trained to ensure they're following all necessary procedures and guidelines. If training is lacking, this can lead to a variety of problems.

5. Failure to report adverse events: Companies are required to report any adverse events related to their products. Failure to do so is a serious violation.

6. Inadequate testing and quality control: Companies must thoroughly test their products and maintain strict quality control. If this is not done, it can lead to serious issues.

7. Non-compliance with labeling regulations: All products must be properly labeled according to FDA regulations. Non-compliance with these regulations is another common problem.

These are just a few examples of the common problems identified in FDA audits. The specific issues found can vary widely depending on the company and the products they produce.
