Trichinella testing in EU pork: what Regulation (EU) 2015/1375 requires

Carcases of Suidae, solipeds and other Trichinella-susceptible species must be examined for the parasite at slaughter under Regulation (EU) 2015/1375 unless one of the derogations in its Article 3 applies. That is the wording of Article 31(1) of Regulation (EU) 2019/627, and the result decides whether the carcase may leave the slaughterhouse.

The legal basis

Commission Implementing Regulation (EU) 2015/1375 of 10 August 2015 lays down specific rules on official controls for Trichinella in meat. It is a codification; Article 15 repeals Regulation (EC) No 2075/2005. It sits inside the official controls framework of Regulation (EU) 2017/625, whose Article 18(4) health mark Article 4(3) refers to.

The text is identical in every Member State; the decisions under it are not. Designating laboratories and recognising, auditing or de-recognising holdings (Articles 8, 10 and 12) belong to national competent authorities, and the central derogation is switched on Member State by Member State.

Which animals must be examined

Article 2(1) splits domestic swine in two. From a holding officially recognised as applying controlled housing conditions, all breeding sows and boars, or at least 10 % of the animals slaughtered there each year, are examined. Everywhere else, all carcases are examined systematically. Article 2(2) adds systematic sampling of solipeds, wild boar and other susceptible species. Annex I fixes the swine sample at 1 g from a pillar of the diaphragm, 2 g for breeding animals and 5 g for cuts of meat.

Fattening pigs versus breeding animals

Article 2(1)(a) keeps breeding sows and boars in the examined population even on a recognised holding: they live far longer than fattening pigs.

The digestion method as the reference

Annex I, Chapter I sets the reference method: artificial digestion to ISO 18743:2015/Amd1:2023. Samples from several carcases are pooled, minced and digested in pepsin and hydrochloric acid, which dissolves muscle but leaves larvae intact; the digest is sedimented and read microscopically. Chapter II lists equivalent methods, several valid only for domestic swine. Trichinoscopy is not among them.

Pooling makes examination viable at line speed. Article 2(3) allows a carcase to be cut into a maximum of six parts pending the result if traceability is guaranteed; Article 4(1) stops it leaving the premises until the result is negative. Positive samples go to a reference laboratory for species determination (Article 6(2)).

Controlled housing conditions

Recognition is granted, not declared

Under Article 8 the competent authority may recognise a holding or compartment meeting Annex IV: buildings closed to rodents, other mammals and carnivorous birds; a documented pest-control programme; feed produced on Regulation (EC) No 183/2005 principles and stored rodent-proof; traceability of each pig; introductions only from equally recognised holdings; and no outdoor access without an accepted risk analysis. Article 10 requires risk-based audits; Article 12, withdrawal.

Recognition alone is not the exemption

Article 3(3) grants the exemption only where the animals come from a recognised holding and the Member State meets one of three conditions: no autochthonous Trichinella infestations in recognised holdings there for three years under continuous testing; historical data giving at least 95 % confidence that prevalence in the slaughtered swine population does not exceed one per million; or the holdings are in Belgium or Denmark. Article 3(4) then requires notification to the Commission and the Standing Committee on Plants, Animals, Food and Feed, and the Commission publishes the list of Member States applying it.

On that list, Belgium and Denmark rely on the third condition, Finland, Italy and Northern Ireland on the first or second. Spain is not on it, so Spanish pigs are examined under Article 2. Check it before accepting any controlled-housing claim.

Freezing as an alternative treatment

Article 3(1) exempts meat of domestic swine that has undergone a freezing treatment in accordance with Annex II under official supervision. Method 1 requires a room at −25 °C or below, for at least 240 consecutive hours up to 25 cm thickness and 480 hours for 25–50 cm. Method 2 sets combinations by thickness: up to 15 cm, 20 days at −15 °C, 10 days at −23 °C or 6 days at −29 °C; 15–50 cm, 30 days at −15 °C, 20 days at −25 °C or 12 days at −29 °C. Ordinary commercial freezing is not this treatment, and Article 3(1) covers domestic swine only — not wild boar or other game.

What the certificate states

The health mark may be applied before results where an approved slaughterhouse procedure guarantees nothing leaves until the examination is negative (Article 4(3)); the identification mark under Regulation (EC) No 853/2004, Article 5(1) and Annex II, Section I, ties the meat to an approved establishment. The obligation follows striated muscle: Article 4(2) lets by-products without it leave before results.

For exports the attestation sits in the certificate agreed with the importing country and signed by the official veterinarian; Spanish models are issued through MAPA's CEXGAN. Inbound, the EU applies the same logic: Article 13(1) admits meat only where examination equivalent to Article 2 or 3 was performed before export, and Article 13(2) limits those derogations to the third countries in Annex VII — currently the United Kingdom alone.

Why third countries ask for it

Trichinellosis is a foodborne zoonosis historically associated with pork, and an importing authority cannot inspect the plant itself; official attestation by the exporting veterinary service is the substitute. Annex VII shows the consequence: an exemption is not portable across a border.

What this means for your order

• Establish which attestation the destination certificate accepts before agreeing the specification; do not assume a controlled-housing option is open to Spanish product.
• Trichinella status attaches to the animal at slaughter; a cutting plant or cold store cannot add it later.
• For frozen product, establish whether freezing was an Annex II treatment under official supervision or ordinary commercial freezing.
• Check the certificate model's scope: the obligation follows striated muscle, so offal and casings may be worded separately.
• Keep the attestation and its evidence aligned. A wrong tick is a border rejection, not an amendment.
