Carcinogenicity data of medicinal products for human use that have been authorised via the European centralised procedure (CP) between 1995 and 2009 were evaluated. Carcinogenicity data, either from long-term rodent carcinogenicity studies, transgenic mouse studies or repeat-dose toxicity studies were available for 144 active substances contained in 159 medicinal products. Out of these compound...

Salmonella and Campylobacter are generally regarded as the most important foodborne pathogens in the world. Reduction or elimination of these pathogens in the first part of the food chain (on-farm) is important to prevent disease among consumers of animal products. Rodents are frequently associated with infrastructural damages and eating or spoiling of stored feed and products, but the veterina...

The commentary by Boettger-Tong et al. (1) described the authors' experience with a commercially available, unidentified rodent diet with high estrogenic activity and the impact of this diet on the normal in vivo uterotropic response of ovariec-tomized 30-day-old Sprague-Dawley rats to exogenously administered estradiol. The purpose of this letter is to corroborate the authors' findings; to rep...

Field study was conducted to evaluate the effectiveness of formulated baits of 0.005% brodifacoum, 0.0375% coumatetralyl, 0.005% bromethalin and 2% zinc phosphide against field rats inhabiting sugarcane crop. The efficacy was calculated on the criterion of reduction in rodent activity, damaged canes and yield of harvested canes. After five applications of baits, the rodent activity reduced to 9...
