Authorities at Muloza immigration office in Mulanje have disclosed that existing porous borders are threats to Malawi’s security and make the country lose revenue through customs duty evasion.

The Ministry of Agriculture and Food Security has backed Plant Protection Officer at Muloza border post in Mulanje for failing to issue general receipts (GRs) for In-Transit permits to cross border traders in perishable produce, saying by law, the officer is not mandated to have the GRs.
