A judge sitting at Manchester county court has ordered the disclosure of all documentary evidence relating to investigations carried out by Public Health England (PHE) surrounding cyclospora — a parasite spread by food contaminated with infected human faeces.

According to The Times, many customers claimed Tui did not tell them the Riviera Maya region of Mexico was subject to a public health warning due to cyclosporiasis before they booked.

This is in spite of 359 of the 440 British cases reported between June and October 2016 "involving travel to Mexico", it is claimed.

Others customers allege they were handed a warning letter “only after their plane landed”.

Tui told TTG it would be inappropriate to comment on the legal process, but added: “We’d like to reassure customers that we regularly audit all of the hotels we feature in respect of health and safety.”
