主要方法:

分析了来自克罗地亚的50个胸和肝脏样本.
使用了液体染色学-双重质谱法 (LC-MS/MS).
用于清理的免疫 afinity 列和用于CPA分析的 QuEChERS.

主要成果:

菌毒素在肝脏中比肌肉组织更为普遍.
在20%的样本中检测到环酸 (CPA),在新鲜肉中首次检测到.

Toxicity Testing in Animals

Toxicity Testing in Animals

Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
