Harvesting shrimp in the old days meant getting down and dirty pond side. Rostra punctures and cuts were the norm. These would rapidly get staph infected and workers would wipe eyes, transfer infection etc.
My cure was garlic to clean cuts. But many use chloramphenicol as cheap and very effective. Of course plastic eye drop bottles get chucked….!
Farm HR protocols may not be tight in that aspect of supporting workers in hazardous jobs. Would be interesting to see what standards policies are….
Blue light might work also somewhere in chain…
