Non-compliant results 2022
1. Report on the investigation of raised lead levels in tissues of a lamb slaughtered at Isle of Man Meats.
Kidney tissue from a lamb sampled at slaughter gave a result of 2.26 mg/kg Lead tissue concentration, tested at AFBI, Belfast. The lamb was sampled as part of routine surveillance for the presence of heavy metals in meat intended for human consumption. An incident is recorded where the kidney or liver lead concentrations exceed 0.5 mg/kg.

Although these tissue levels may not be high enough to cause clinical signs of lead poisoning, they are still important in terms of food residues and food safety. A farm visit and investigation, revealed that the most likely the source of lead in this case was geochemical associated with old lead mines present at the grazing site. The farm is located to the south of the central belt of the Isle of Man. The lamb was from a group of approx. 200 fattening lambs aged 9 -12 months. No clinical signs were reported in the lamb or any of the group. Advice was given to the owner on geochemical lead and the public health implications. He is planning to take steps to address the issue.
2. Report on the investigation of Florfenicol detected in a bulk milk sample
AFBI confirmed that detection of Florfenicol had been confirmed in the sample IOM/MILK/2022/010. Of its requested tests:
- Chloramphenicol: FLORFENICOL DETECTED
- Action level type: PRESENCE.
- CCalpha (decision limit) 0.34.
- From https://www.sciex.com/content/dam/SCIEX/pdf/tech-notes/all/CCalpha-and-CCbeta-Automatic-Calculation-SCIEX-OS.pdf: “The decision limit CCa means the limit at and above which it can be concluded with an error probability of α (1% for substances with non-permitted limits and 5% for substances with a permitted limit such as the Maximum Residue Limit (MRL)) that a sample is non-compliant”
- Concentration detected 0.55 ug/kg. Ergo NON-COMPLIANT.
- AMS1: compliant
- Cefquinome: compliant
- Anthelmintics: compliant
Florfenicol is not authorised for use in cows producing milk for human consumption, or pregnant cows due to produce milk for human consumption. So just presence of Florfenicol is a non-compliance (it is authorised for other bovine animals).
Follow up sample was taken which was compliant for Florfenicol.
On farm investigation indicates accidental administration of this drug, the farmer has now put extra precautions in place to prevent this happening again.
