Repeated poisoning of Flamingos in the Po Delta



In November 2006, more than 20 Greater Flamingos (Phoenicopterus roseus) were found dead in the Po Delta, NE Italy, because of a severe event of lead shot poisoning. 16 of them were collected and several lead pellets were present in their gizzard cavities. Chemical and histopathological analyses confirmed the suspect of lead shot poisoning. The average of lead concentration in hepatic tissue was 108,41 ppm, a value higher than 8 ppm, the threshold in aquatic birds(*). This case confirms the importance to forbid the lead pellets used in hunting shotgun shells in Italian wetlands. Nevertheless, local regional government never agreed to stop using lead pellets in the protected wetlands, so more cases of dead Flamingos were registered in the same area exactly one year later.

I'm not within the healthcare career, and while I'm sure that there сould be some гationale for that argument,
I woulԁn't opportunity not having antibiotics for strepEVER. Several several years ago my good friend died from coronary heart failure, the direct result of an untreated strep infection. Then, last spring, my sister went into harmful shock/sepsis from the neglected strep throat. She approximately died. Several organs failing...it was terrible. She was in intensive look after weekly. With the boost of invasive team A strep infections today, including the flesh having micro organism (necrotizing fasciitis), not taking antibiotics for strep would be like enjoying Russian roulette. Strep is absolutely nothing to mess around with individuals.
