This article supports food producers answer the question, “What are GMPs?”

Introduction to GMPs

Good Manufacturing Practices (GMPs) are the set of production standards that have been embraced by regulators, retailers and consumers in the food and drug industries. 

GMPs provide a basic assurance that a product was produced under industry-standard conditions. Some of the areas addressed in GMPs include:

  • Building & facility conditions

  • Equipment design and maintenance

  • Employee practices

  • Sanitation conditions

  • Raw ingredient sourcing

  • Maintaining strong production controls

  • Records and reports


There are several sets of GMP standards which have been endorsed by different governments. Fortunately although they are nearly identical. Some versions of GMPs include:

  • CGMP* (food) addresses the production of food for the US.

  • CGMP* (drug) addresses the production of pharmaceutical drugs for the US

  • EU-GMP addresses the production of pharmaceutical drugs for the European Union

  • Guide 104 GMP addresses the production of pharmaceutical drugs for Canada

If you are considering aligning your business with GMPs, adopt the set of standards that reflects where your processing is located and where your product will be sold. If this includes more than one set of GMPs, you will want to make sure your operations are aligned with both. Again, they are nearly identical.

*CGMP stands for “Current Good Manufacturing Practices” and is regulated by the FDA.

Food vs. Drug GMPs

In the United States, the FDA defines two distinct sets of GMP standards — Food and Pharmaceutical (Drug).

Food CGMPs: These describe the “methods, equipment, facilities, and controls for producing processed food.” (FDA, 2004). These are meant to ensure that the food is safe to eat.

Drug CGMPs: These assure “the identity, strength, quality, and purity of drug products by requiring that manufacturers of medications adequately control manufacturing operations”. (FDA, 2018).

The sections below reflect the GMP requirements for food.

Understanding the GMP Certification Process

After a food manufacturer aligns their operations with GMPs, they may consider going through the certification process through a private auditing firm. This is how the certification process typically works:

  1. A manufacturer adopts the GMP standards and makes the required adjustments to align with the standards. Depending on the preexisting practices and conditions, this could take 3-12 months.

  2. The manufacturer chooses a private auditing firm (there are many) to conduct the GMP audit.

  3. The auditing firm conducts the audit, which may include an inspection of the facility and a review of records. 

  4. The manufacturer will correct any areas of non-compliance and, if they achieve a passing score, they will receive a certificate from the auditing firm.

  5. The manufacturer can provide this certificate to prospective buyers as an indication of their alignment with industry standards.

Why You Should Align Your Operations with GMPs

Regardless of whether your business chooses to pursue certification, aligning your operations with GMPs will have the following benefits:

  • Decrease in food safety risk to your customers

  • Lower level of product defects

  • When your buyers conduct supplier verification activities, they will want to want to know that your operations are GMP-aligned — even if you’re not certified


The Benefits of Achieving GMP Certification

  • It will unlock access to the many buyers who require GMP certification from their suppliers.

  • It will satisfy most supplier-verification requirements — meaning less back-and-forth between your team and the companies you sell to.

  • You will have an advantage over competitors who haven’t been certified to this industry standard.

Part 117 Subpart B: Current Good Manufacturing Practices

What You Need to Know

Part 117 Subpart B is called Current Good Manufacturing Practices (CGMPs)

These CGMPs outline the major requirements that a food processor must adhere to, including:

  • Facility requirements

  • Employee requirements

  • Equipment requirements

  • Cleaning requirements

  • Warehousing & Distribution requirements

Summary of Current Good Manufacturing Practices

This text is aligned with the coding used in the FDA Regulations so that you can hunt down the corresponding section with ease.

For example,  you have a question about my wording in §117.110 (b) (2) then just look up this same code in the CFR.

117.10 Personnel:

For a reduced summary of this section, see Personnel

a. Disease Control: Sick employees must be excluded from operations that could result in food contamination

3. Drain areas (i.e. puddles) that may breed pests or contribute to food contamination

4. Even if the grounds aren’t in your control, you must still mitigate contamination hazards.

b. Plant Construction & Design: The space must be suitable in size, construction and design for food production.

1. Must have adequate space for equipment and storage.

2. Must allow you to take precautions which reduce allergen contamination and food contamination (for example -- by chemicals, filth, other materials). Ways to eliminate contamination include separating operations by: location, time, partition, air flow systems, dust control system, etc.

3. Protect food that is stored outside in bulk containers:

4. Floors, Walls, Ceilings must be constructed in a way that allows them to be cleaned. The construction of the space must allow employees to do their jobs and not contaminate food, packaging, and work areas.

5. There should be adequate lighting in all food and employee areas (including food storage areas and employee locker rooms). All bulbs and glass that is suspended over areas where food is exposed should be shatter resistant.

6. There should be adequate ventilation to minimize dust, steam, odors, and vapors.

7. Provide screens or other protection against pests (door sweeps, air curtains)

§117.35 Sanitary Operations

d. Sanitation - You must clean food contact surfaces, including utensils, tables, equipment, to protect against contamination.

1. If you process low moisture (dry) food, your food contact areas must be clean and dry before use.

2. In “wet processing” food processing areas must be cleaned before use and after any contamination occurs.

3. Paper towels, paper cups and other single-use items must be protected from contamination.

e. Non-food-contact-surfaces (i.e. walls, ceilings or anything that doesn’t touch food) must be cleaned as much as necessary to prevent contamination of food, packaging, or work areas.

f. Portable equipment and utensils must be stored in a way that doesn’t contaminate work areas.
