Reliability begins with following and understanding best practices. Good Manufacturing Practices (GMPs) are the foundation to building operational and maintenance best practices to manage food safety risks. For the food industry, GMP's come from the FDA in 21 CFR- Part 110.

So far in this series we have discussed parts of 21 CFR- part 110, now it is time to roll up our sleeves and get started on forming a plan. Assessments are both a great place to start and a good way to maintain processes and controls. When you read the questions, think about how does maintenance personnel, activities and actions contribute to improving food safety.

The assessment below can be used as a guide for areas that your plant may want to look at in developing or improving your maintenance program. Before you start look at other assessments and audits that have been done. Keep a sharp eye open for problems that could have been prevented by a proactive maintenance program and should be added to this assessment. Good Manufacturing Practices can actually save your company money by increasing quality and reducing waste.

1. The assessment questions are only a beginning point and should be expanded upon or modified depending on your processes and condition of your facility. Citing the applicable GMP regulations, ( ) will be helpful in verifying that your process complies with the requirements of the FDA and other external auditing bodies.

2. Rate each response either compliant or non-compliant. Make note of your evidence to support your rating.

3. When asked questions about batching and raw material sampling, think about access to do the activities, PM's performed in the area and potential food safety risks due to equipment, access and procedures. Use at least 3 production batches for sampling to verify the results. Testing should include all stages of the process from raw ingredients coming to the final product in the warehouse.

Good Manufacturing Processes:

Personnel and Training

Compliance Rating
