Pathogen testing in the product
Salmonella, Listeria, E. coli and Staphylococcus in the finished product - the key indicator of whether the batch is safe to consume.
Food Testing for Plants
In a food plant, every batch that leaves the production line carries your brand name. Periodic sampling of products, raw materials and intermediates catches microbial contamination or a chemical exceedance before the product reaches the shelf. Kesar Digum collects representative samples along the line through certified samplers, sends them for testing at an ISO 17025 accredited laboratory and supports your HACCP program, nationwide.

Food Testing for Plants
Every batch ships with proof of safety
A food plant is required to run an organized monitoring program that follows the product from raw material to finished batch. Microbiological and chemical testing along the line confirms that the production process stays under control and that the product meets the standards and the customer specification. Kesar Digum builds the sampling plan with you, collects the samples under a controlled cold chain through certified samplers, and returns a clear report that fits into your HACCP file and Ministry of Health inspections.

What the service includes
What we sample on the line
Targeted sampling at the critical control points of the production process - per your HACCP plan.
Bacterial count and chemical parameters
Total bacterial count, yeasts and molds alongside chemical parameters, pesticide residues and metals by product type.
Incoming raw material testing
Sampling raw materials and intermediates as they enter the line, to catch contamination before it enters the production process.
Complementary environmental sampling
Monitoring surfaces, equipment and the production environment to detect Listeria, as an added layer of protection for the product.

Regulation
When is a plant required to sample?
A food plant's monitoring program is derived from the regulations and the product type. These are the common situations:
Ongoing monitoring program
A food plant runs a periodic sampling program for the product and raw materials, as part of its HACCP file and quality control.
Releasing a new batch
Batches of high-risk products are tested before release to market, as a condition for approving their safety.
After a change in the process
A new product, a change to the line, a deep clean or a production stoppage all require sampling to confirm a return to control.
Suspected exceedance
A borderline result, a customer complaint or suspected contamination requires targeted sampling and a check of the source along the line.
What's at risk
What does a contaminated batch that slipped through cost?
In a plant, a single failure multiplies into thousands of units that have already left the gate. Here's what's at stake:
Recall and inventory write-off
A contaminated batch that reaches the shelf triggers a costly recall, inventory destruction and a line shutdown - far beyond the cost of the test.
Harm to consumers
A pathogen in a widely distributed product can cause a broad disease outbreak, with health damage to consumers across the country.
Regulatory and brand exposure
A monitoring failure exposes the plant to citations in a Ministry of Health inspection, a line closure and serious damage to the brand's reputation.

Q&A
Frequently Asked Questions About Food Plant Sampling
We’ve gathered the most common questions about sampling and testing in food plants, including the regulatory side, so you can build a testing program that meets the standard and protects your brand.
When is sampling required in a food plant?
Food plants are required to run routine laboratory testing of raw materials, finished products and the production environment as part of their food safety program (HACCP or GMP) and as a condition for obtaining and renewing a manufacturer's license. Systematic environmental monitoring is the first line of defense that prevents Listeria, Salmonella and recalls.
What is sampled in a food plant?
Sampling covers finished product, raw materials and, above all, environmental monitoring (swabs from surfaces, drains, equipment and hard-to-clean areas) to detect pathogens, alongside in-process water testing. The combination catches contamination before it ever reaches the product.
How does the sampling process actually work?
A certified sampler builds a sampling plan based on the critical control points (CCP), takes sterile samples on site, maintains the cold chain and transfers them to an accredited laboratory. Full details on the food sampling page.
What happens if a result comes back out of spec?
You activate the corrective action plan: holding the relevant batch, tracing the source of contamination, thorough cleaning and disinfection of the area, and a confirmatory re-sample before production resumes.
How do you prepare properly for sampling?
Keep hygiene and sanitation procedures consistent, document your control points, and set a sampling frequency based on the risk level of the product. Systematic preparation reduces out-of-spec results and keeps production running.
What does the law say about sampling in food plants?
The Public Health Protection (Food) Law and the adoption of European regulatory principles require compliance with strict threshold levels for biological and chemical contaminants, and periodic laboratory testing is the practical way to demonstrate self quality control. Non-compliance or out-of-spec results can jeopardize the manufacturer's license and trigger a recall.
