Technical rules for assessing carry-over in delivery trucks

These simple technical rules were developed as part of a study programme led by Tecaliman, and funded by the association and the DGAl (French Directorate of Food).

The rules were established based on the results of this study, summarised in i’Tec_H7 and presented in more detail in Special Report No. 53.

By way of introduction to these rules, it is useful to review certain study conclusions:

• Flushing between batches, especially after at-risk batches, is a vital preventive measure in the fight against carry-over.

• Medicated feedstuff transport is made safe by using newer trucks.

• Inter-box carry-over proved to be generally insignificant. The study demonstrated that this type of carry-over could be dealt with by visually checking the internal cleanliness of the boxes after a delivery of animal meal.
