A team of researchers from Universiti Malaya, led by Assoc Prof Dr Siti Nursheena Mohd Zain, recently found a high prevalence of food poisoning bacteria on the hands of restaurant workers, particularly the foreign labourers, working in the food service industry. This certainly calls for improvements in the personal hygiene and sanitation standards in Malaysia’s food service industry!
As of late, there have been a lot of temporary closure of dirty food eateries (for example Raj’s Banana Leaf), and the Government needs to address the systemic issue, they said. According to The Star, the parasitologist revealed that hand swabs taken from 383 legal migrant workers handling food in three cities – Ipoh, Kuala Terengganu and Shah Alam – almost all indicated potential health hazards.
It also showed that 64% of the workers sampled had high counts of Staphylococcus aureus which exceeded acceptable levels of hygiene while one-fifth showed high levels of Escherichia coli (E. coli). These bacteria can cause a host of medical conditions, some of which that can be fatal.
According to the researchers, food handlers are one of the major sources of foodborne disease outbreaks in Malaysia. “The findings indicate high probability of transmission of pathogenic bacteria from the food handlers’ hands to customers during meal preparation and serving and this calls for improvements in personal hygiene and sanitation standards by the relevant health authorities,” Dr Siti Nursheena told The Star.
The foreign workers who participated in the study mostly consisted of those who entered the country recently but the results on high infection rate did not show much difference for length of stay in Malaysia. The workers who were sampled came from India, Indonesia, Bangladesh, Nepal, Myanmar, Thailand, Sri Lanka, Pakistan and Vietnam, and worked in places like ‘Mamak’ shops, coffee shops, cafes and hawker stalls.
In another study using the same samples, it was found that 3% of workers carried non-typhoidal Salmonella and they exhibited resistance to a broad range of antibiotics. “A high prevalence of these hand-contaminating bacteria serves as an indicator of poor hygiene and reflects the degree of contamination of raw foods, equipment and the kitchen environments,” she said.
Dr Siti also said that the temporary closure of premises is only a superficial gesture. She hopes that there will be better attempts made to address some of the more systemic issues affecting the industry.
