Dairy Testing for the Safety of Milk Products

Safety, Quality & Compliance Solutions for the Dairy Value Chain

Dairy Milk Lifecycle

In today’s dairy industry, ensuring safety, quality, and efficiency throughout the supply chain—from farm to final product—is essential. PerkinElmer, through its Meizheng subsidiary, delivers a fully integrated portfolio of dairy testing solutions that support every stakeholder, from producers and transporters to processors. Their comprehensive product range includes rapid test kits and advanced instruments designed for the fast and reliable detection of antibiotic residues, pesticide residues, mycotoxins, illegal additives, adulteration, hormones, and nutrients. Whether for on-site screening or high-throughput laboratory analysis, PerkinElmer’s dairy testing solutions empower the industry with the speed, accuracy, and confidence needed to meet global food safety standards.

Dairy Testing Solutions - Safety of Milk Products

From Raw Milk to Consumer Shelf — Complete Dairy Testing Solutions for Every Stage

1 - Veterinary Drug Residues

DASH Kit: Microbial inhibition

DASH Test Kit
Dairy Antibiotics Spore High-Throughput Kit. A qualitative test based on microbial inhibition, capable of detecting over 60 antimicrobial drugs across 8 major antibiotic classes in raw milk. Designed for high-throughput, large-volume on-site screening, this solution provides farmers with a practical early-warning tool to ensure milk safety and compliance with regulatory MRLs. Read more

Anti-Fungal

Anti-Parasitic

NSAID

2 - Illegal Additives & Contaminants

Melamine

Melamine is a nitrogen-rich compound illegally added to increase apparent protein content, posing health risks and banned in food and feed.

Illegal Additive - Melamine

Beta-Lactamase

Beta-lactamase is used to degrade antibiotic residues in milk, masking contamination and compromising food safety. Beta-lactamases are enzymes produced by bacteria that provide multi-resistance to Beta-lactams antibiotics.

Preservatives , Disinfectants

Nitrate, Nitrite (Preservatives)

Chlorine, Hydrogen Peroxide (Disinfectants)

3 - Mycotoxins

Mycotoxins are toxic compounds produced by fungi that can contaminate feed and dairy, posing serious health risks to animals and humans.

Mycotoxins Field to Silage

5 - Pesticides

Ensure safety of milk and dairy products by detecting pesticide residues in raw milk and animal feed.

Pesticide Residues in different Regions
Cows - Pesticides

6 - Pathogen & Microbiological Testing

Only 3 steps

MicroFast® microbial count plates are a rapid and reliable microbial testing solution, which can greatly improve the efficiency of laboratory testing and is widely accepted by enterprises. Read more

Main reason of gastrointestinal infections:

Staphylococcus aureus can produce extracellular protein toxins—known as enterotoxins—under suitable conditions. The classical enterotoxins include types A, B, C, D, and E, all of which are associated with vomiting and food poisoning.

8 - Pasteurization Validation

Proper pasteurization can guarantee milk safety as well as maintain most nutrients. Alkaline Phosphatase (ALP), Lactoperoxidase (LPO) are key indicators to evaluate whether the milk has the proper pasteurization process:

Heat damage and nutritional integrity:

Pasteurization

9 - Adulteration

Milk adulteration remains a major concern, ranging from the addition of small molecules like melamine for fraud to the unregulated mixing of cheaper cow milk into premium species milk such as sheep or buffalo:

Microbiology Test Platform

MicroFast® microbial count plates are ready-to-use plates designed for rapid and accurate enumeration of microorganisms in food, dairy, and environmental samples. They offer a simplified alternative to traditional pour plates, enabling easy operation, shorter incubation times, and clear colony interpretation for total plate count, coliforms, yeast & mold, and specific bacteria.

Microbial Count Plate Workflow
  1. Inoculation – Lift the top film and add sample.
  2. Incubation – Incubate the plates following instruction.
  3. Interpretation – Count the colonies.

ELISA Test Kits

A highly sensitive immunoassay that detects target substances through antigen-antibody interactions and enzyme-driven signal generation. In competitive ELISA, more antigen in the sample means fewer antibodies bind to the plate, enabling quantification.

ELISA

Immunoaffinity columns (IAC)

IAC uses toxin-specific antibodies bound to a gel matrix to selectively capture target analytes such as mycotoxins in food and feed. Impurities are washed away, and the purified analyte is eluted, allowing for efficient sample cleanup and concentration. This process enhances the accuracy and sensitivity of downstream analysis by methods like HPLC or LC-MS/MS. Read more
