Given the advance of river floods linked to the El Niño phenomenon, the National Service of Agrifood Health and Quality (SENASA) has facilitated procedures for the transfer of animals from areas affected by hydrological contingencies and reiterates to producers the importance of adopting preventive measures to protect the health and welfare of the herd.
According to the records of the national sanitary agency, since August, 147,500 bovines and buffaloes have been evacuated from the flooded regions in the provinces of Corrientes, Chaco, Entre Ríos, Santa Fe, and the island areas of Buenos Aires.
The number of mobilized animals increased by 102% compared to the same period in 2025 and required 7,448 transfers, formalized with the issuance of the electronic Transit Document (DT-e). These figures correspond to a partial balance to date, although movements are expected to continue increasing as the situation evolves in each region.
In order to expedite the evacuation and the procedures associated with the transfer of animals, SENASA has facilitated for producers, among other administrative procedures, the issuance of the DT-e and the registration of producers in the National Sanitary Registry of Agricultural Producers (RENSPA), so that they can respond to the operational and logistical urgencies of the moment.
In addition, exceptional measures are foreseen for compliance with sanitary movement requirements, which must be completed when the livestock arrives at the destination establishment.
Given this situation, SENASA recalled some guidelines to facilitate the evacuation and management of animals during the emergency:
• Anticipate where to shelter the animals. Identify high pastures or safe areas and stock up on food and drinking water.
• Initiate the transfer 24 to 48 hours before the water arrives. It is recommended to carry out the roundups in small groups to reduce stress.
• Mark the animals with veterinary aerosol paint on their backs, to recognize them from a distance during the emergency.
• If evacuation is not possible, open gates and internal fences. Animals will be able to move by themselves to higher ground.
When the water recedes, it is recommended to provide safe water, check the condition of the hooves, and keep the sanitary plan updated. This prevents diseases such as leptospirosis and foot rot, and those associated with an increase in ticks, such as anaplasmosis and babesiosis.
Animals transferred from the islands may not be familiar with the plant species in the destination fields. Therefore, SENASA recommends monitoring that they do not consume toxic plants, including mío-mío (Baccharis coridifolia), which is very dangerous for bovines not accustomed to it.
It is advisable to check the pastures before releasing the livestock, avoid lots with the presence of these plants, offer forage and water upon arrival, and observe the animals during the first few days. In case of any abnormal signs, such as tremors, drooling, or weakness, it is suggested to immediately contact a veterinarian or the SENASA offices in the jurisdiction.
