CHEMICAL CONTAMINANTS CHECKS |
The target of contaminants checks division is to verify the conformity to food safety criteria.The continuous evolution of food-processing, market globalization, the eventual environmental contaminations and possible fraudulent behaviours make it necessary to perform specific, accurate and fast checks in order to guarantee food safety.
Moreover Regulation CEE n. 466/2001 and subsequent developments introduced maximun residues levels for some heavy metals (lead, cadmium, mercury) and mycotoxins in order to protect public health considering the toxicity of these elements and substances.
Main analyses and services
The division activity develops on different kinds of tests most of them are under SINAL accreditation.
Analytical determination of plant protection residues on a huge number of matrices such as:
 cereals and derivatives - fruits and vegetables and derivatives
- meat, eggs and derivatives
- milk and derivatives
- oils and fats
- wines and beverages
- water
- spices and herbs, coffee, cocoa, etc.
- baby food
- feedstuffs
Most of the molecules are determined with multiresidual techniques and the analytical screening is as much as possible targeted and representative for the product which is analyzed.
The continuous updating of analyses make it possible to offer a wide range of analytical determinations according to the more and more varied market requirements.
For example, we report some of the most frequently performed analytical determinations:
- Organophosphorus insecticides, organochlorine insecticides, pyrethroid insecticides, carbamates, growth regulators, acaricides
- Phenylurea, nitroaniline, triazine herbicides and others
- Benzimidazole fungicides, dithiocarbamates, thiophthalimide, pyrimidine, triazole fungicides and others
- Plant growth regulators
- Fumigants
- Numerous individual substances
Analytical determination of mycotoxins
- Aflatoxins type B, G, M
- Ochratoxin
- Trichothecenes (deoxynivalenol, nivalenol, 3-acetyldeoxynivalenol, fusarenon, T-2 toxin, HT-2 toxin, T-2 triol, T-2 tetraol, diacetoxyscirpenol, verrucarol)
- Fumonisins
- Zearalenone
- Patulin
- Citrinin
 Analytical determination of heavy metals (lead, cadmium, chromium, nickel, iron, copper, zinc, mercury, arsenic, tin, selenium, etc.)
Analytical determination of polychlorinated biphenyls (PCB)
Analytical determination of veterinary drugs residues
- Tetracyclines on milk and derivatives, honey, meat, fish, eggs, feedstuffs

- Isoniazide on milk
- Abamectine, ivermectin on meat, milk and derivatives, fruits
- Macrolides
- Colistin sulphate on medicated feedstuffs
- Malachite green, leucomalachite green on fish and derivatives
Analytical determination of hormones residues
- Corticosteroids on milk and meat
- Synthetic hormones with androgenic, progestinal and estrogenic activity on meat
Analytical determination of polyciclic aromatic hydrocarbons (PAH)
On matrices such as sausages, fish, tea, cocoa, oil, barley, officinal herbs.
Analytical determination of azo dyes and other dyes
Azo dyes (Sudan I, II, III, IV, Para Red, Dimetil yellow, Sudan Orange G, Sudan Red 7B, Sudan Red B, Sudan Red G, Orange II) on flavours, sausages, condiments, foodstuffs, spices, seasoning agents; dyes such as Rhodamine B on spices, foodstuffs.
Other analytical determinations
- ESBO and phtalates on oil, foods in oil, vegetable condiments, vegetable preserved foods, sauces, pesto sauce, etc.
- Acrylamide on roasted coffee and coffee beverage, cereals.
- Furan e methylfuran on coffee and coffee beverage, foodstuffs, vegetable condiments, fruit juices.
- ITX on foods.
