The EFSA Scientific Panel on Plant Health considered the Spanish pest risk analysis (PRA) and has agreed with the conclusions on risk of island apple snail Pomacea insularum with regard to (i) the potential consequences of the organism for rice crops are major; (ii) the probability for establishment of the organism is very likely and (iii) the probability of spread is estimated as likely. But the Panel does not think that the effects on the environment would be massive and the probability of entry of the organism to be high. The EFSA opinion will help the European Commission and its Standing Committee on Plant Health to decide on possible regulation of this snail species complex. EFSA is the EU risk assessment body for food and feed safety. It provides independent scientific advice to risk managers. Delete the scoop?

Most rust fungi are highly host specific, but Puccina psidii has an extremely broad host range within Myrtaceae and gained notoriety with a host jump in its native Brazil from common guava (Psidium guajava) to commercial Eucalyptus plantations. When detected in Hawai‘i in April 2005, the first invasion outside the neotropics/subtropics, there was immediate concern for Metrosideros polymorpha.
