New Standard Release: IS 5404:2024 - Ensuring Microbiological Safety in Food Sampling and Testing
The Bureau of Indian
Standards (BIS) has released the updated IS 5404:2024 standard, describe about
the procedures for the sampling, transport, storage, and preparation of food
samples for microbiological analysis. Following are the key highlights,
laboratories, and the food industry:-
1. Expanded Scope to
Cover More Food Categories
The IS 5404:2024 standard
applies to a broad range of food products, from raw and processed meats to
dairy products, beverages, fruits, vegetables, and specialty foods like spices,
confectioneries, and frozen items. Each category has unique preparation, handling,
and storage protocols to ensure sample integrity from the point of collection
to the sample receipt by laboratory.
2. Emphasis on
Representative Sampling
In microbiological
testing, the quality of results depends heavily on the representativeness of
the sample. IS 5404:2024 introduces comprehensive guidelines on sampling,
stressing statistical significance and proper techniques to ensure that
collected samples accurately reflect the food lot's microbiological
characteristics. This emphasis minimizes the risk of misleading test results,
which can impact both food safety and public health.
3. Enhanced Transport and
Storage Protocols
The standard important
points is the proper transport and storage of samples to preserve microbial
integrity. It includes detailed instructions for different storage requirements
based on product type: chilled samples (2-8°C), frozen samples (below -15°C),
and ambient-stable products. IS 5404:2024 specifies equipment and conditions
for safe transport, such as using insulated containers, temperature monitoring
devices, and maintaining a strict cold chain for perishable items. These
measures ensure that samples arrive at the laboratory in a condition that
accurately reflects their original state.
4. Detailed Sample
Preparation Techniques
The standard addresses
the unique preparation needs of various foods. For example:
- High-fat foods
require emulsifiers like polysorbate to ensure proper mixing.
- Acidic foods
need specific diluents for pH adjustment, while dehydrated products
should be handled carefully to avoid osmotic shock.
- Special diluents and homogenization
methods are recommended for products with
high viscosity, dry texture, or other physical complexities.
By establishing clear methods for different food types, IS 5404:2024 helps laboratories
achieve consistent, reliable results regardless of sample complexity.
5. Compliance with Modern
Food Safety Regulations
The standard aligns with
requirements under the ISO/IEC 17025 guidelines for testing laboratory
competence. This international alignment means that laboratories adhering to IS
5404:2024 are better prepared for regulatory compliance and meet global food safety
standards, particularly important for businesses involved in both domestic and
international markets.
6. Benefits for the Food
Industry and Consumers
By adopting IS 5404:2024,
food businesses can bolster their quality control processes, protecting
consumer health and enhancing product trust. Accurate microbial testing plays a
critical role in preventing foodborne illnesses, identifying contamination sources,
and verifying hygienic practices throughout the supply chain. This standard not
only aids food safety but also supports the industry's reputation by setting a
higher benchmark for quality assurance.
The release of IS
5404:2024 marks a significant advancement in food safety and testing practices. As the food laboratory continues to expand scope with new products and
complex supply chains, this standard provides an essential framework for Sampling, Transport, Storage and Sample Preparation of Food Samples microbiological analysis. Adopting these guidelines will
enable laboratories and food producers to meet regulatory requirements while
ensuring the highest levels of safety and quality for consumers.
