According to the BBC, a spokesman from Air India said the incident involved a leading caterer who supplies all US airlines.
He said that the food was picked up in the US not in India.
He described the incident as 'very rare' adding that normally caterers had very strict hygiene conditions.
The spokesman said that 'a full investigation' into the incident was now under way.
