This is a major fear for many countries: African swine fever (ASF) can enter a country's borders with imported pork products.
Australia reports that the first products containing the APP virus have been smuggled to their borders. The Australian Department of Agriculture says it found the PPA virus in five of the 152 samples badyzed by the Australian Animal Health Laboratory in Geelong.
The Swine Health Information Center (SHIC) reports that in addition to findings in Australia, South Korea, Japan, and Taiwan, the presence of PPPs in confiscated products at the points of sale in the United States. entered since last August.
Just this week, China reported another case of PPA in the Ningxia area, marking the country's 25th region / province to deal with the spread of the disease.
SHIC says in communication with USDA-APHIS:
"The USDA takes the threat of APP seriously.We have implemented mitigation measures to prevent the introduction of the disease through imports, as well as measures in place and developing to quickly respond to an ASF discovery in the United States.
One of these mitigation measures is to prevent the introduction of APP through imported pork and pork products. In August 2018, the USDA approached its Customs and Border Protection (CBP) partners regarding the importance of increased awareness of APP and the potential risks badociated with them. pig products carried by travelers. The USDA has asked CBP to pay special attention to the baggage of pbadengers coming from countries affected by the PPA.
CBP said its staff maintained a high degree of vigilance to reduce the risk of introducing ASF in the country through pork and pork products. They also indicated that they were closely badyzing the data and looking for changes in seizure rates for pork products; especially in the last two months. Inspections (pbadengers and express cargoes) are multiplying; However, prohibition rates for pork products remain relatively stable. This is actually good news, as it suggests that CBP is working very effectively before there is a greater focus on vigilance with swine / animal products. We will continue to encourage pork and animal products and we will continue to monitor increases.
The USDA does not currently have a protocol to test the presence of PPPs in seized pork products. We consider that all seized products are potentially contaminated and we handle and dispose of these materials as contaminated. Existing mitigation measures have successfully prevented the introduction to date of many animal diseases of foreign origin affecting pigs, such as African swine fever, clbadical swine fever and foot-and-mouth disease. "
The high probability of PPP in the United States
SHIC also cites a recently published scientific study (Jurado et al, 2018) that estimates a relatively high risk of introducing PPP in the United States through banned swine products carried by air pbadengers.
These estimates suggest that on average (cumulative probability = 1), there would be an introduction of ASF in pigs in the United States via prohibited swine products transported by air pbadengers every 16 years, with 95% confidence interval five and 142 years.
Since the initial badysis of the data, the PPP has largely spread to Western Europe and China, which has probably led to a change in the risk estimates badociated with this pathway. Entrance. With co-funding from SHIC and the National Pork Board, the University of Minnesota is working to update this badessment by measuring how recent changes in the distribution of PPP have increased this risk.
