The European Commission also stated in January 2004 that manufacturers would have to stop using semicarbazide
in sealants for glass jars and bottles by October 2005.

Derivatization was carried out as follows: 500 [micro]L of plasma, calibrator, quality controls, or diluted hemolysate (300 [micro]L of red cells + 700 [micro]L of water) and 40 g/L of derivatizing agent (containing 250 g/L semicarbazide
and glycine) were combined, vortex-mixed, and left in the dark at room temperature for 30 min.
It was found that glucose, semicarbazide

Scientists at Reading Scientific Services Ltd (RSSL) have won the race to develop a reliable method for detecting semicarbazide
in metal lids.
As reported in The Grocer last week (p6), the European Food Safety Authority warned seals on jars contained cancer-causing toxin semicarbazide
TheEuro-pean Food Safety Authority (EFSA) examined the risk of semicarbazide
(SEM) which had been found in certain foods packed in glass jars and bottles with metal lids sealed with plastic gaskets.
The European Food Safety Authority (EFSA) said any risk from semicarbazide
(SEM), which has been found in certain foods packed in glass jars and bottles with metal lids sealed with plastic gaskets, was "very small".
