Breastfeeding after taking a shot of cordon Bleu

Hello mummies. I’m currently doing confinement. A month before I gave birth my hubs soak cordyceps with cordon Bleu in a jar, Was told by friend that after 12 days of confinement it’s good to take a shot of it. Now my questions is, can I still breastfeed after taking that 1 shot? Or I should pump it out to throw it away?
