Accidental contamination

Accidental contamination analysis aims to identify and quantify undesirable substances present in a product, ingredient, or production environment. These contaminants can be chemical, physical, or biological in origin, and their detection is essential to ensuring product safety, regulatory compliance, and quality. When a foreign body, residue, or anomaly is discovered, precisely identifying its nature and origin is the first step in addressing the problem and preventing its recurrence.

Why analyze accidental contamination?
Unidentified contamination can have major consequences: non-compliance, batch recalls, supplier disputes, or even risks to consumer health. Laboratory analysis helps answer several crucial questions: What substance is it? Where did it come from (raw material, process, packaging, environment)? What is its concentration? By establishing the nature and source of the contaminant, the analysis provides an objective basis for taking corrective action, documenting a quality file, or determining liability. It is a crisis management tool as well as a preventative measure in the food, cosmetics, nutrition, environmental, and materials sectors.

What investigation methods are used?
Identifying accidental contamination relies on an investigative approach combining several techniques, chosen according to the suspected nature of the contaminant:

• Spectroscopic analyses, FTIR and Raman, to identify residues, films or organic foreign bodies (see our article on FTIR spectroscopy).
• Chromatographic analyses, GC-MS and LC-MS/MS, to detect traces of solvents, plasticizers, hydrocarbons or other organic compounds.
• Elemental analysis (ICP-MS) to detect metals or mineral impurities.
• Visual and microscopic examinations (SEM / SEM) to locate and characterize particles, fibers or films.
• Microbiological and molecular analyses (microbial identification by DNA) when the contamination is of biological origin.

What matrices and associated analyses are involved?
The matrices involved are highly varied: raw materials, finished products, packaging, water, powders, liquids, and technical materials. Depending on the context, this analysis is similar to other services in our catalog: deformulation ( see our article on deformulation) to identify the complete composition of a product, or the quantification of a pollutant in a sample for a known target. This service covers the agri-food, cosmetics , and environmental, among others.

Why choose YesWeLab?
At YesWeLab, we collaborate with a rigorously selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC).
