INTRODUCTION• Food safety has been given worldwide recognition
as a major concern since it impacts health.
• Food safety involves actions aimed at ensuring that all food is as safe as possible. Since food contamination can occur at any stage, from farm to table, good safety policies and actions need to address the entire food chain, (farm to fork model).
• Food contamination can be caused by microbial, chemical or physical hazards.
• Chemical hazards include toxic metals, poly-chlorinated, biphenyls and pesticides.
To assess farmers’ state of knowledge, attitudes and current practices (KAP) regarding the use of pesticides, and their exposure to these agrochemicals used on farms in selected communities in Guyana, St. Kitts/Nevis, St. Lucia and Trinidad and Tobago
OBJECTIVES OF THE RESEARCH
To determine the level of pesticide residues in tomatoes from farms in Guyana and Saint Lucia
To explore the relationship between level of pesticide residues in tomatoes from the selected farms and farmers’ KAP.
Methodology: Cross-Sectional Survey
15 communities were targeted in 4 countries -

Population
Quantitative and qualitative data were collected from 737 farmers, using piloted questionnaire.
Systematic sampling th(every n farm was
used to identify the farmers in each community)
METHODOLOGY: LABORATORY EXPERIMENT A purposive sampling
method was used.
10 farms in Black Bay and its environs, Saint Lucia.
11 farms in Parika, Guyana
9 farms in Black Bush Polder, Guyana
•Samples (1 kg of mature tomatoes in each case) were collected twice during the harvest period, based on a systematic and defined pattern (referred to as an ‘X’ pattern).
A multi-residue analysis based on fifty- two active ingredients (pyrethroids, organochlorine and organophosphorous pesticides) was utilised .

Inferential StatisticsThe association between knowledge and attitude; knowledge and
practice and attitude and practice
INFERENCES There is a weak inverse relationship between
knowledge and attitude (as in the case of Guyana).
There is a weaker inverse relationship between knowledge and practice, but it is not significant (as in the case of Saint Lucia).
There is a relatively strong positive relationship between attitude and practice: attitude positively influences practice (as in the case of Saint Kitts/Nevis).
Laboratory Results for samples taken from
Black Bay, Saint Lucia
Detectable pesticide residues were found in 3 of the 10 samples; and then in 4 of the 10 samples in the first and second sampling, respectively.
Pesticide residues that were present were:
cypermethrin < 0.2 mg/kg
profenofos < 10 mg/kg
permethrin < 1 mg/kg
All of the pesticide residues detected were below their Codex maximum residue limits (MRLs).
Laboratory Results for samples taken from
Parika, Guyana
In both the first and second sets of samples, pesticide residues were detected in 2 of the 11 (samples)
Pesticide residues that were present were: chlorpyrifos, cypermethrin, triazophos.
Pesticide residues were found above their Codex MRLs in 2 of first set of samples; and in 1 of
second set of samples:
cypermethrin (0.23 mg/kg as compared to MRL of 0.2 mg/kg)
triazophos (0.12 mg/ kg as compared to MRL of 0.01 mg/kg)
Laboratory Results for samples taken from Black Bush Polder,
Guyana
Pesticide residues were detected in 4 of the 9 samples; and then in 1 of the 9 samples during the first and second samples, respectively.
Pesticide residues that were present were: profenofos and cypermethrin
Pesticide residues were found above the Codex MRLs in 1 sample each in the first and second sets of samples:
cypermethrin = 0.23 mg/kg as compared to 0.2 mg/kg.
Results - exploration of relationship between the
level of pesticide residues and farmers, KAP
St. Lucia had the highest percentage (36%) of farmers with high level of knowledge relating to pesticides. Note: pesticide residues levels were below the MRLs.
In Guyana, in Black Bush Polder and Parika where pesticide residues showed higher levels than the MRLs, 24% and 18% of the farmers displayed low knowledge of pesticides, compared to 13% in Saint Lucia.
A higher percentage of farmers in Guyana had neutral and negative attitudes regarding the risks associated with the application of pesticides.
CONCLUSION Farmers' KAP with regard to pesticides use
vary within and across countries.
Practice does not necessarily change with an increase in knowledge.
Good practice increases with the correct attitude.
Abuse of pesticides in the targeted countries is minimal considering the MRLs ; however, percentage of samples that exceeded these levels is higher than percentages recorded by researchers from other developing countries.
No organochlorine pesticide residues were detected in samples analysed.
Periodic testing of crops for pesticides residues is necessary.
Need for increased knowledge on pathways of pesticide, IPM etc.
Monitoring by Extension Officers is vital .
More education (long term tool, using formal and non-formal
Experiential learning through demonstration more projects may change attitude and practice
