BIS Notifies Amendments to Food Chain Microbiology Standards for Food Testing

The Bureau of Indian Standards (BIS) has notified amendments to six food chain microbiology standards. These BIS food chain microbiology standards guide how laboratories test food for harmful microbes. The notification came on July 13, 2026, and was published in the Gazette of India on July 15, 2026.

This update matters because these standards decide how food testing labs check for viruses, bacteria, and parasites in food. When BIS changes these standards, every lab that uses them must change too.

The amendments cover method validation protocols, virus detection methods, bacteria detection methods, and parasite detection methods. Each of the six standards received "Amendment No. 1," dated July 2026.

Food manufacturers, food testing laboratories, exporters, meat processors, dairy companies, and seafood companies are all affected. Government labs and research institutions that test food samples must follow these updated standards too.

Organizations should take necessary actions well in advance because the existing guidelines will remain applicable until January 2, 2027. Once this period elapses, the only guidelines that will be applicable are those that have been revised. Delaying will lead to complications.

Background of the Framework

What are Food Chain Microbiology Standards?

Food chain microbiology is the study of tiny living organisms found in food. These organisms include bacteria, viruses, and parasites. Some of them make food unsafe to eat.

Food testing checks whether these harmful organisms are present in food before it reaches consumers. Laboratories run these tests to confirm food is safe.

Laboratories perform microbiological testing for several reasons:

• To find bacteria like Campylobacter that cause food poisoning
• To detect viruses like Hepatitis A and Norovirus that spread through contaminated food
• To catch parasites like Trichinella larvae found in meat
• To confirm that a testing method actually works before using it on real samples

Food safety depends on accurate testing. If a lab uses a weak or outdated method, harmful microbes can slip through undetected.

What is BIS?

BIS stands for Bureau of Indian Standards. BIS is India's national organization that establishes standards regarding safety and quality across industries.

BIS develops standards because there is a need for standards in India in order for there to be uniformity in regard to the processes of testing, manufacturing, and quality control.

Here are reasons why BIS standards are significant:

• BIS standards provide laboratories with a standardized approach to adhere to
• BIS standards assist manufacturers in achieving uniform quality levels
• BIS standards ensure that consumers are protected from substandard products
• BIS standards aid in enabling Indian organizations to meet international trading requirements

For businesses, following BIS standards builds trust with customers and regulators. For consumers, it means safer food and products.

Why Does BIS Align with ISO Standards?

ISO stands for International Organization for Standardization. ISO standards are rules created by international experts and accepted by countries around the world.

The BIS frequently brings Indian standards in line with the ISO standards since consistency is beneficial to all. When India follows the same standards that other countries follow, international trading is easier.

Advantages of this practice include:

• Testing is conducted using internationally accepted procedures
• Indian test certificates are more acceptable internationally
• Exporters are rejected less at foreign border crossings
• Companies do not have to maintain two separate testing systems for domestic and international products

This is exactly what has happened with the current amendments. Each amended IS (Indian Standard) is mapped directly to its ISO equivalent, keeping India's food testing framework in step with global science.

Which BIS Standards Have Been Amended?

BIS has issued Amendment No. 1 to six microbiology standards used across the food testing industry. The table below lists each standard, its ISO equivalent, and its purpose.

Here is what each standard actually does:

• IS 17113 (Part 3 and Part 4) deal with method validation. Before a lab uses any test, it must prove the test works correctly. These two standards give labs the exact steps to check and confirm a method's accuracy, either by comparing it to a known reference method or by validating it from scratch.
• IS 18350 (Part 1) covers virus testing. It tells labs how to detect and measure Hepatitis A virus and Norovirus in food using a technique called real-time RT-PCR. This method is common for testing shellfish, leafy vegetables, and frozen fruit.
• IS 18564 (Part 1 and Part 2) focuses on Campylobacter, a bacterium that commonly causes food poisoning from undercooked poultry. Part 1 explains how to detect the bacteria, and Part 2 explains how to count colonies once detected.
• IS 18569 addresses Trichinella, a parasite found in pork and other meats. This standard gives labs a method to digest meat samples artificially and check for parasite larvae.

What Has Changed Under the Latest BIS Amendment?

Each of the six standards has received Amendment No. 1, dated July 2026. The amendment became effective on July 3, 2026.

Key points about the change include:

• All six standards are being updated to Amendment No. 1
• The updates apply to laboratory testing procedures used across the food industry.
• The changes bring these standards closer to their current ISO counterparts.
• Businesses using older versions of these standards need to switch to the amended versions before the transition period ends.

No line-by-line changes have been made in the notification by BIS have been given by BIS except the number of amendments and the amendment date. The laboratories are advised to look at the BIS-amended standard documents when they are ready for exact wording instead of making any assumptions.

Labs can expect the following practically:

• Revised procedure for the laboratories as per the revised ISO standards
• Enhanced validation for proving the accuracy of the tests
• Higher degree of consistency between the Indian test results and international test results
• Ease in the acceptance of the Indian lab reports internationally

Why Has BIS Introduced These Amendments?

BIS regularly updates standards to keep pace with new science and global practices. These amendments serve several goals:

• Improved food safety through advanced techniques that effectively detect pathogens
• Enhanced testing accuracy through improved protocols that minimize testing errors
• Scientific validity through standards based on the latest advances in microbiology
• Improved consumer protection against foodborne illnesses through accurate food testing
• Harmonization through conformity with the ISO, thereby helping Indian food products compete internationally

These modifications are not mere random changes; rather, they are part of an ongoing process to ensure that the Indian food testing system remains up to date.

Effective Date and Transition Timeline

Businesses and laboratories need to track key dates carefully to avoid compliance gaps.

After January 2, 2027, laboratories and businesses must follow the amended versions of all six standards. Continuing to use the old, unamended standards after this date could lead to non-compliance.
