The accred­ited method researches lesions on bovine target organs that may be traced to illegal treat­ment with anabolic steroids or growth enhancers. In addi­tion to the histo­log­ical reports, the Laem­megroup Labo­ra­tory provides micro­scopic images of the most pronounced lesions and offers consul­tancy from the time of drawing samples to inter­preting the diag­nostic results.

Recently, histology has been applied to the analysis of meat-based prod­ucts and prepa­ra­tions to provide a micro­scopic assess­ment of any muta­tions to the muscle-fibre struc­ture in the meat.


Filth Test

The filth test enables singling out and iden­ti­fying any solid impu­ri­ties present in food and provides impor­tant indi­ca­tions on the whole­some­ness and hygienic condi­tions of the food in rela­tion to the stages of processing and conser­va­tion. Solid impu­ri­ties are consti­tuted by all the solid parti­cles that are foreign to the normal compo­si­tion of the food and that cannot be discerned by the naked eye due to their micro­scopic size.

The filth test enables clearly iden­ti­fying these and distin­guishing them by type of origin:

  • Animal (insects and mites or their frag­ments, insect or mite eggs, fur, barbs of bird feathers, faeces,etc.)
  • Vegetable (seeds, extra­neous vegeta­bles, wood frag­ments, textile fibres, etc.)
  • Mineral (grains of sand, crys­tals, etc.)
  • Synthetic (fibres, plastic frag­ments, etc.)

Research of animal origin constituents in animal feed

Annex IV of Regu­la­tion 999/2001 regu­lates admin­is­tra­tion of tradi­tional agri­food prod­ucts to the different animal species and this was modi­fied by Regu­la­tion (EU) 56/2013, which autho­rises the use of tradi­tional agri­food prod­ucts orig­i­nating from non-rumi­nant animals (pigs and poultry) in fish food. Research on animal origin constituents in animal feed is conducted by the Laem­megroup Labo­ra­tory according to the provi­sions of Regu­la­tion (EU) 51/2013.

The qual­i­ta­tive method is based on recog­nising animal origin constituents that can be iden­ti­fied with a micro­scope, such as muscular fibres or other parti­cles from:

  • Meat
  • Carti­lage
  • Bone
  • Horn
  • Fur
  • Bris­tles
  • Blood
  • Feathers
  • Egg shells
  • Fish bone
  • Scales

Research on foreign bodies and/​or parasites

The Laem­megroup Labo­ra­tory conducts research and iden­ti­fies foreign bodies and/​or para­sites found in food­stuffs. The report is accom­pa­nied by macro­scopic and micro­scopic images.
