A method of monitoring compatibility to avoid contamination of cargo within a transport container , the method comprising: reading, using a scanner device , data tags associated with cargo entering the transport container; and storing, using a memory storage device , data from the data tags; and characterised by analyzing, using a verification management system , the compatibility of the cargo in response to the data, the verification management system coupled to the memory storage device, the verification management system including: a verification compatibility module to determine possible contamination element pairs in response to the data, wherein the verification compatibility module determines if cargo entering the transport container is compatible in response to the possible contamination element pairs; and a verification invoice module to determine if at least one of past cargo and future cargo is compatible with cargo entering the transport container in response to the possible contamination element pairs, wherein the verification invoice module is compiled from an end user API including information comprising meat invoices , fish invoices and produce invoices ; and transmitting an alert notification to the scanner device, using the verification management system , when it is determined that cargo entering the transport container should not be stored within the transport container as it is not compatible with at least one of past cargo and future cargo. reading, using a scanner device , data tags associated with cargo entering the transport container; and storing, using a memory storage device , data from the data tags; and characterised by analyzing, using a verification management system , the compatibility of the cargo in response to the data, the verification management system coupled to the memory storage device, the verification management system including: a verification compatibility module to determine possible contamination element pairs in response to the data, wherein the verification compatibility module determines if cargo entering the transport container is compatible in response to the possible contamination element pairs; and a verification invoice module to determine if at least one of past cargo and future cargo is compatible with cargo entering the transport container in response to the possible contamination element pairs, wherein the verification invoice module is compiled from an end user API including information comprising meat invoices , fish invoices and produce invoices ; and transmitting an alert notification to the scanner device, using the verification management system , when it is determined that cargo entering the transport container should not be stored within the transport container as it is not compatible with at least one of past cargo and future cargo. a verification compatibility module to determine possible contamination element pairs in response to the data, wherein the verification compatibility module determines if cargo entering the transport container is compatible in response to the possible contamination element pairs; and a verification invoice module to determine if at least one of past cargo and future cargo is compatible with cargo entering the transport container in response to the possible contamination element pairs, wherein the verification invoice module is compiled from an end user API including information comprising meat invoices , fish invoices and produce invoices ; and transmitting an alert notification to the scanner device, using the verification management system , when it is determined that cargo entering the transport container should not be stored within the transport container as it is not compatible with at least one of past cargo and future cargo. <EOS>
