Conclusions and Recommendations

ByAcknowledgements

The research demonstrates that typical microbiological and pesticide contamination levels of vegetables in Ghanaian markets pose a threat to human health. It has also shown that the majority of microbial and parasitological contamination of lettuce produced from urban sources in Accra and Kumasi comes from wastewater, application of manure and residual soil contamination. Results also show that the post-harvest sector is probably a relatively minor contributor to lettuce contamination.
