During the last few decades, the German meat industry has experienced an incomparable economic expansion, becoming one of the largest European producers and exporters in the sector. At the same time, Germany, traditionally characterized as a coordinated market economy with strong social partners and labour market institutions, has been nationally as well as internationally criticized for establishing a system of institutional exploitation of mobile and migrant labour in the industry. The aim of this article is to analyse how it was possible to create and maintain such a system under the eyes of social partners and to identify the defining factors for this development.

The industrial hemp sector is growing and, in recent years, has launched many novel hemp-derived products, including animal feed. It is, however, unclear to what extent individual cannabinoids from industrial hemp transfer from the feed into products of animal origin and whether they pose a risk for the consumer. Here we present the results of a feeding experiment with industrial hemp silage in dairy cows. Hemp feeding included changes in feed intake, milk yield, respiratory and heart rates, and behaviour. We combined liquid chromatography–tandem mass spectrometry-based analyses and toxicokinetic computer modelling to estimate the transfer of several cannabinoids (Δ9-tetrahydrocannabinol (Δ9-THC), Δ8-THC, Δ9-tetrahydrocannabinolic acid, Δ9-tetrahydrocannabivarin, 11-OH-Δ9-THC, 11-nor-9-carboxy-Δ9-THC, cannabidiol, cannabinol and cannabidivarin) from animal feed to milk. For Δ9-THC, which has a feed-to-milk transfer rate of 0.20% ± 0.03%, the acute reference dose for humans was exceeded in several consumer groups in exposure scenarios for milk and dairy product consumption when using industrial hemp to feed dairy cows.
