Residue Analyses
What is Residue / Contaminant? Substances that are applied for any purpose during the processes of obtaining food and reaching our table, depending on the conditions after the application or not, deteriorating or without deterioration, the final amount he final amount that is remaining in the product of which must be controlled is called residue.
They are contaminants that contaminate food due to environment or production-processing-storage area, etc. and undesirable to be found in food product, and generally have harmful/toxic effects. Major residue and contaminants:
- Pesticide residues
- Veterinary drug residues
- Hormones
- Heavy metals
- Mycotoxins,
- Substances that pass from packaging materials to the product
- Dioxin, furan, PCB
The most important problems encountered in agriculture and animal husbandry are pesticides, veterinary drugs, hormones, antibiotics and their derivatives that are used unconsciously. As a result of exceeding the legal limits determined both in our country and in Europe, pesticides, veterinary drugs, hormones and antibiotics leave residues in plants and animal products, and this threatens both human and animal health.
Frequently Asked Questions
-
What is Pesticide Residue Analysis?
Pesticide residue analysis determines whether pesticide levels in food, fruits, and vegetables are within legal limits. The goal is consumer safety and regulatory compliance.
-
Why Are Pesticide Tests Important?
They verify chemical residues are at safe levels. Excessive or banned residues can harm human health and prevent products from reaching the market.
-
Which Products Require Pesticide Residue Analysis?
Fruits, vegetables, grains, dairy, meat, and processed foods. The scope depends on product type and intended use.
-
Which Methods Are Used for Pesticide Analysis?
Modern chromatography methods such as GC-MS, LC-MS/MS, and HPLC detect even trace residues accurately.
-
Which Standards Apply to Pesticide Tests?
Tests follow ISO 17025, Codex Alimentarius, and national food regulations. Compliance ensures product safety and international market acceptance.
-
Which Parameters Are Measured?
Pesticide type, concentration, and maximum allowed residue limits are measured. Both quantitative and qualitative analyses are possible.
-
How Long Does Pesticide Testing Take?
Typically 3–7 days, depending on the number of pesticides and sample type. Comprehensive tests may take 1–2 weeks.
-
Why Is Pesticide Analysis Important for Health?
Excess residues can cause poisoning, allergies, and long-term health issues. Testing ensures safe and healthy food consumption.
-
Is Pesticide Testing Mandatory for Imported Products?
Yes, imported foods must undergo pesticide residue testing. Accredited lab reports are required for customs and import procedures.
-
How is Pesticide Analysis Conducted in the Lab?
It involves sample preparation, extraction, cleanup, and analysis. Modern instruments ensure accurate and reliable results.
-
How Are Costs Determined?
Depends on number of pesticides tested, sample quantity, and methods used. Comprehensive testing can be costly but is essential for safety.
-
Is Pesticide Testing Important for Food Labeling?
Yes, results provide reliable labeling information, especially for organic or low-residue certifications.
-
How Are Pesticide Test Results Interpreted?
Reports include pesticide type, concentration, and comparison with legal limits. Expert review ensures safety and compliance.
-
How Do Pesticide Tests Affect the Environment?
Proper use and residue control protect soil and water. Lab analysis minimizes environmental risks.
-
Why Should Pesticide Tests Be Conducted in Accredited Labs?
Accredited labs follow ISO/IEC 17025 standards. Reports are officially valid and accepted for CE marking, export, and inspections.
