A survey conducted by the Pesticides Regulatory Office (PRO) of the Mauritian Ministry of Agro-industry, Food Security, Blue Economy, and Fisheries, has revealed that nearly half of the fruit and vegetable samples tested contained pesticide residues. Between May and July, 151 samples were collected and analyzed by the Food Technology Laboratory and private laboratories. The results showed that 52.32% of the samples had no detectable residues, while 13.25% had residues within the maximum limits.
However, the survey also found that 6.62% of the samples had residues exceeding the maximum limits, and 29.80% contained pesticides not recommended for the specific crop. These findings have raised concerns about the use of pesticides in Mauritian agriculture and the potential risks to human health. Amarjeet Beegoo, a planter, beekeeper, and agricultural consultant, attributed the problem to the lack of technical training among some new producers.
Beegoo noted that some farmers, who take up agriculture as a complementary activity, rely heavily on advice from phytosanitary product vendors. This can lead to the use of aggressive combinations of insecticides, which can result in higher residue levels. He explained that the type of pesticide used can affect the level of residues found on the produce, with systemic products being more difficult to remove through washing.
The survey's findings also highlighted the challenges faced by producers, including the pressure to produce perfect-looking products and the risk of crop losses due to pests and diseases. Beegoo noted that the market demand for flawless produce can lead some farmers to apply more treatments, which can increase the risk of residue contamination.
The issue of pesticide residues is not limited to conventional agriculture. According to data from the European Food Safety Authority, residues have been detected in some organic produce. Similarly, hydroponic farming is not exempt from food safety concerns, with the Food and Agriculture Organization (FAO) highlighting risks of microbiological contamination.
Beegoo emphasized the need for improved training and phytosanitary surveillance to address the challenges faced by producers. He also highlighted the impact of climate change, which is leading to the emergence of new pests and diseases, further complicating the work of farmers.
The Mauritian Ministry has established a national program for monitoring pesticide residues in fresh agricultural products. The program involves regular sampling and analysis of produce from various sources, including markets, supermarkets, and ports of entry. When residues are detected, the ministry issues "improvement notices" to ensure that producers comply with regulations.
Key points
- 47% of fruit and vegetable samples tested contained pesticide residues.
- The survey found that 6.62% of samples had residues exceeding the maximum limits.
- The issue of pesticide residues is not limited to conventional agriculture, with organic and hydroponic produce also posing risks.
