The department has facilitated the importation of fertile eggs for the broiler industry and, it said “a similar request for the table eggs will be considered if received”.
It is also facilitating the transit to Eswatini of fertile eggs for their broiler production.
The department has met with vaccine registration regulators and it was agreed that the registration of vaccination will be quick tracked. However, the meeting agreed that safety, efficacy and quality will not be compromised.

“The criteria under which vaccination will be permitted is almost in its final development, and only farms with qualified biosecurity and approved to vaccinate by the department will be given permission to vaccinate. The other requirements for vaccination will be surveillance to enable early detection of incursion and imperative slaughter of vaccinated chickens.
“The department further encourages all producers to intensify their biosecurity measures on the farm. The basic measures should aim at preventing contact with wild birds, including their faecal material, which can be transported in boots and equipment,” the department said. – SAnews.gov.za
