Lead exposure in common shelduck (Tadorna tadorna): Tracking the success of the Pb shot ban for hunting in Spanish wetlands.

The objective was to assess Pb exposure in waterfowl, fourteen years after the implementation of the Real Decreto 581/2001, which banned the use of Pb ammunition for hunting activities in internationally relevant wetlands. For this purpose, this study measured the actual ingestion of lead pellets in Common shelduck from La Albufera de Valencia and provide data on Pb residue concentrations in different tissues of this species breeding in this NP. The Pb distribution pattern in tissues was bone > kidney > liver > brain > muscle, with Pb concentrations of 778.96 ± 998.64, 122.40 ± 89.18, 92.08 ± 57.65, 18.90 ± 16.30 and 15.13 ± 11.85 ng/g (wet weight), respectively. This work presents, as far as we are aware, the first published data on Pb concentrations in Common shelduck. The Pb levels detected were lower than those reported in other studies on Anatid species from Spanish wetlands, which may be explained by this ban. Moreover, lead concentrations found were below those levels for which any observable effect has been described for acute or chronic lead exposure. PMID: 31063795 [PubMed - as supplied by publisher]

Foodborne botulism is an intoxication caused by ingestion of food containing botulinum neurotoxin. Cases of foodborne botulism are usually sporadic (single, unrelated) but outbreaks of two or more cases occur. In this mini-review we will examine the following for the period 2001–2017, in the United States: botulism surveillance data, outbreaks of botulism affecting 10 or more people, and the public health preparedness and response approach.

Online ahead of print.ABSTRACTIn October 2019, ninety-four patients were admitted into Alexandria Poison Center (APC) with a history of ingestion of Feseekh (salted fish). In an attempt to allocate the resources, not all patients were given HBAT (botulism antitoxin heptavalent (A, B, C, D, E, F, G) equine immediately. The current study aimed to portray the clinical characteristics of the cases, explore the possible relation between these characteristics and necessity of HBAT administration, explore the reliability of mouse lethal test, and establish ...

Purpose of review The incidence rates of the toxin-related infectious diseases, tetanus, diphtheria and botulism declined dramatically over the past decades mainly because of the implementation of immunization programs also in low-and-middle-income countries (LAMICs) and by improving hygiene conditions. But still, single cases occur, and they need fastest possible recognition and management. Recent findings Over the past 20 years, the incidence of neonatal tetanus has declined by more than 90%. This success was achieved by immunizing women in reproductive age in areas of high risk as sub-Saharan Africa and par...

MMWR Recomm Rep. 2021 May 7;70(2):1-30. doi: 10.15585/mmwr.rr7002a1.ABSTRACTBotulism is a rare, neurotoxin-mediated, life-threatening disease characterized by flaccid descending paralysis that begins with cranial nerve palsies and might progress to extremity weakness and respiratory failure. Botulinum neurotoxin, which inhibits acetylcholine release at the neuromuscular junction, is produced by the anaerobic, gram-positive bacterium Clostridium botulinum and, rarely, by related species (C. baratii and C. butyricum). Exposure to the neurotoxin occurs through ingestion of toxin (foodborne botulism), bacterial colonization of...
