Steven J Lehotay, Yelena Sapozhnikova, Lijun Han, John J Johnston,

Nitrites are added as a preservative to a variety of cured meats, including bacon, to kill bacteria, extend shelf life, and improve quality. During cooking, nitrites in the meat can be converted to carcinogenic nitrosamines (NAs), the formation of which is mitigated by the addition of antioxidants. In the past, ... Read more >>

Perfluorooctane Sulfonate Plasma Half-Life Determination and Long-Term Tissue Distribution in Beef Cattle (Bos taurus).

Sara J Lupton, Kerry L Dearfield, John J Johnston, Sarah Wagner, Janice K Huwe,

Perfluorooctane sulfonate (PFOS) is used in consumer products as a surfactant and is found in industrial and consumer waste, which ends up in wastewater treatment plants (WWTPs). PFOS does not breakdown during WWTP processes and accumulates in the biosolids. Common practices include application of biosolids to pastures and croplands used ... Read more >>

Absorption and excretion of 14C-perfluorooctanoic acid (PFOA) in Angus cattle (Bos taurus).

Sara J Lupton, Janice K Huwe, David J Smith, Kerry L Dearfield, John J Johnston,

Perfluoroalkyl substances (PFASs), such as perfluorooctanoic acid (PFOA), are environmentally persistent industrial chemicals often found in biosolids. Application of these biosolids to pastures raises concern about the accumulation of PFOA in the edible tissues of food animals. Because data on the absorption, distribution, metabolism, and excretion (ADME) of PFOA in ... Read more >>

Barnett A Rattner, Katherine E Horak, Rebecca S Lazarus, Karen M Eisenreich, Carol U Meteyer, Steven F Volker, Christopher M Campton, John D Eisemann, John J Johnston,

In the United States, new regulatory restrictions have been placed on the use of some second-generation anticoagulant rodenticides. This action may be offset by expanded use of first-generation compounds (e.g., diphacinone; DPN). Single-day acute oral exposure of adult Eastern screech-owls (Megascops asio) to DPN evoked overt signs of intoxication, coagulopathy, ... Read more >>

Evaluation of cocoa- and coffee-derived methylxanthines as toxicants for the control of pest coyotes.

John J Johnston,

Methylxanthines were quantified in coffee, tea, and chocolate products. Tarajuilie tea from India, cocoa powder, and cocoa nibs contained the highest levels of methylxanthines. Theobromine, caffeine, and theophylline combined in the ratios observed in tea and chocolate were ingested by coyotes. Although both mixtures induced acute toxicity, the symptoms accompanying ...
