Results of recovery experiment 1 after spiking and washing 300 g of lettuce with different numbers of sodium hypochlorite resistant (SHR) taeniid eggs (Echinococcus multilocularis and Taenia polyacantha) or embryonated Toxocara eggs. PCR results show the proportion of positives out of five or three replicates.
