The Telekom Affair – In May 2007, several former riders admitted to using banned substances (including EPO ) while riding for the team in the mid-1990s, including Erik Zabel , Rolf Aldag , Brian Holm ,  Bjarne Riis ,  Bert Dietz , Udo Bölts and Christian Henn including the seasons in which Riis and Jan Ullrich won the Tour de France.  Team doctors Andreas Schmid and Lothar Heinrich also confessed to participating and administering banned substances. The latter was Team Telekom's sporting director until 3 May 2007, when he was suspended following allegations published in former team member Jef d'Hont 's book. 
The preservative benzyl alcohol has been associated with serious adverse events, including the "gasping syndrome", and death in pediatric patients. Although normal therapeutic doses of this product ordinarily deliver amounts of benzyl alcohol that are substantially lower than those reported in association with the "gasping syndrome", the minimum amount of benzyl alcohol at which toxicity may occur is not known. The risk of benzyl alcohol toxicity depends on the quantity administered and the liver and kidneys' capacity to detoxify the chemical. Premature and low-birth weight infants may be more likely to develop toxicity.
