Health officials in both the United Kingdom and the United States are monitoring a rising number of infections caused by a parasite that can lead to severe gastrointestinal illness.
In the United States, thousands of people have become ill, and authorities are still investigating the source of the outbreak.
According to the U.S. Food and Drug Administration (FDA), part of the outbreak has been linked to iceberg lettuce imported from Mexico, The Sun reports.
At the same time, officials are continuing to investigate other possible sources of contamination.

How to reduce the risk
The UK Health Security Agency advises travellers to drink bottled water and eat food that has been thoroughly cooked.
Raw salads, fresh herbs, berries, and unpeeled fruit should be avoided.
The parasite is spread through contaminated food or water and cannot be transmitted directly from one person to another.
For that reason, prevention mainly depends on good food hygiene practices.

More travellers fall ill after holidays
According to the UK Health Security Agency, as cited by The Sun, 67 cases were recorded among British travellers between 30 April and 15 July.
Most of those affected had travelled to Mexico, while a smaller number had also visited the United States or Kenya.
Many of the infected travellers had stayed at all-inclusive resorts in Cancún and Riviera Maya.
Authorities are continuing their investigation and advise anyone who experiences diarrhoea, stomach pain, nausea, fatigue, or loss of appetite after travelling abroad to contact a doctor and provide details of their travel history, according to the UK Health Security Agency.
