Lot ZX1449F: this was a production run of bacta manufactured by the Xucphra Corporation. The bacta within ZX1449F was sabotaged by Ashern insurgents, and subsequently shipped to Coruscant, resulting in the infection of two million individuals. Every patient who received treatment utilizing this batch developed a severe bacta allergy, and roughly two percent developed blastonecrosis.
Following this discovery, Ysanne Isard took action to eliminate the compromised batch by releasing it into the black market.
